Downloading Software

The Cisco MDS NX-OS software is designed for mission-critical high availability environments. To realize the benefits of nondisruptive upgrades on the Cisco MDS 9500 Directors, we highly recommend that you install dual supervisor modules.

To download the latest Cisco MDS NX-OS software, access the Software Center at this URL:

http://www.cisco.com/cisco/software/navigator.html?a=a&i=rpm

See the following sections in this release note for details on how you can nondisruptively upgrade your Cisco MDS 9000 switch. Issuing the install all command from the CLI, or using Cisco DCNM for SAN to perform the downgrade, enables the compatibility check. The check indicates if the upgrade can happen nondisruptively or disruptively depending on the current configuration of your switch and the reason.

Compatibility check is done:
Module  bootable          Impact  Install-type  Reason
------  --------  --------------  ------------  ------
     1       yes  non-disruptive       rolling
     2       yes      disruptive       rolling  Hitless upgrade is not supported
     3       yes      disruptive       rolling  Hitless upgrade is not supported
     4       yes  non-disruptive       rolling
     5       yes  non-disruptive         reset
     6       yes  non-disruptive         reset
 
   

At a minimum, you need to disable the default device alias distribution feature using the no device-alias distribute command in global configuration mode. The show incompatibility system bootflash:system image filename command determines which additional features need to be disabled.

NPE Software Images

No payload encryption (NPE) images are available with some releases of Cisco MDS NX-OS Release 5.2(x) software. The NPE images are intended for countries who have import restrictions on products that encrypt payload data.

To differentiate an NPE image from the standard software image, the letters npe are included in the image name as follows:

m9500-sf2ek9-kickstart-mz-npe.5.2.2.bin

m9500-sf2ek9-mz-npe.5.2.2.bin

When downloading software, ensure that you select the correct software images for you Cisco MDS 9000 Series switch. Nondisruptive software upgrades or downgrades between NPE images and non-NPE images are not supported.

Upgrading Your Cisco MDS NX-OS Software Image

This section lists the guidelines recommended for upgrading your Cisco MDS NX-OS software image and includes the following topics:

Upgrading to Cisco NX-OS Release 5.2 from Release 5.0(8)

Upgrading Guidelines Specific to NX-OS Release 5.2(2a)

General Upgrading Guidelines

Nondisruptive Upgrade Paths

FICON Supported Releases and Upgrade Paths


Note Before you begin the upgrade process, review the list of chassis and modules that Cisco MDS NX-OS Release 5.2(2) supports. See the "MDS 9000 Chassis and Module Support" section.


For detailed instructions for performing a software upgrade using Cisco DCNM, see the Cisco DCNM Release Notes, Release 5.2, which is available from the following website:

http://www.cisco.com/en/US/products/ps10495/prod_release_notes_list.html

Upgrading to Cisco NX-OS Release 5.2 from Release 5.0(8)

A nondisruptive software upgrade from NX-OS Release 5.0(8) to any NX-OS Release 5.2(x) requires a module reload if you have any of the following modules deployed in your Cisco MDS 9000 system:

DS-X9224-96K9, 24-Port 8-Gbps Fibre Channel Switching Module

DS-X9248-96K9, 48-port 8-Gbps Fibre Channel Switching Module

DS-X9248-48K9, 4/44-Port Host Optimized 8-Gbps Fibre Channel Switching Module

DS-X9304-18K9, 18/4-Port Multiservice Module (MSM-18/4)

If you perform a nondisruptive software upgrade from NX-OS Release 5.0(8) to any NX-OS Release 5.2(x) on a Cisco MDS 9222i switch, you must reload the switch following the upgrade.

In addition, some features and applications might stop working if they are running on a Cisco MDS 9000 system that uses the hardware devices mentioned previously. These features and applications include IVR, IOA, SME, DMM, fcflow, and SPAN.

For additional information, see Field Notice 63504. The open caveat CSCty32238 also provides details.

Upgrading Guidelines Specific to NX-OS Release 5.2(2a)

Follow these guidelines when upgrading to Cisco MDS NX-OS Release 5.2(2a):

Follow the upgrade path to NX-OS Release 5.2(2a) that is specified in Table 11.

Upgrade to NX-OS Release 5.2(x) before you install any Generation 4 module in an MDS 9500 Series switch. Generation 4 modules include the FCoE module and the 32-port and 48-port 8-Gbps Advanced Fibre Channel modules. NX-OS Release 5.2(x) is needed for the switch to recognize the new hardware.

Perform a full switch reload on an MDS 9509 or MDS 9506 switch after you install NX-OS Release 5.2(1) and install any Generation 4 module, including the FCoE module. The switch reload is required for the new hardware to come up. Once you perform the switch reload, the fabric mode changes to support the Generation 4 hardware. Because of the changed fabric mode, you cannot subsequently perform a nondisruptive software downgrade from NX-OS Release 5.2(1). For additional information, see the "Downgrading Guidelines Specific to NX-OS Release 5.2(2a)" section

Ensure that you have a Supervisor-2A module (DS-X9530-SF2A-K9) installed in a MDS 9500 Series switch if you plan to use the Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) (DS-X9708-K9).

We recommend that you delete any SPAN configuration, Fibre Channel tunnel, or tunnel-ID map configuration from your switch before you start the upgrade to NX-OS Release 5.2(1). You can save the SPAN destination and SPAN target configuration and then reconfigure the SPAN session following the upgrade. All SPAN destination and SPAN target ports are reinitialized after the upgrade. To gather information about SPAN sessions and delete them, use the following commands in this order:

show incompatibility systems bootflash:image_name to display any incompatible configurations

show span session to check the current configuration for a SPAN session

no span session session-number to delete a SPAN session

show running-config | include fc-tunnel to check the current Fibre Channel tunnel configuration

no interface fc-tunnel y to delete a Fibre Channel tunnel on the switch that is the source for the Fibre Channel tunnel

show interface brief | include SD to check the current configuration for a SPAN destination port configuration

show interface brief | include ST to check the current configuration for a SPAN target port configuration

no fc-tunnel tunnel-map z interface x/y to remove an Fibre Channel tunnel map

no switchport mode sd to negate the SPAN destination port mode for the SPAN destination port

no switchport mode st to negate the SPAN target port mode for the SPAN target port

If you are using IVR non-NAT mode, migrate to IVR-NAT mode before you upgrade to NX-OS Release 5.2(1). IVR non-NAT mode is deprecated in NX-OS Release 5.2(1).


Note In dual SAN fabrics, IVR traffic can use one fabric while the other fabric is migrating. Only IVR traffic is disrupted during the migration. Regular traffic within the VSAN is not disrupted during the migration.


To migrate to IVR-NAT mode, follow these steps:

1. Stop or divert all applications on servers that depend on IVR.

If CFS distribution is not enabled for IVR, then perform steps 2 through 4 on all switches where IVR is enabled.

If CFS distribution is enabled for IVR, then enter the ivr commit command following step 2, step 3, and step 4 to distribute the changes to other switches.

2. Deactivate the IVR zone set by entering the no ivr zoneset activate command.

3. Enable IVR NAT by entering the ivr nat command.

4. Activate the IVR zone set by entering the ivr zoneset activate command.

5. Start or re-establish all application that were stopped in step 1.

The network can now run in IVR-NAT mode.

General Upgrading Guidelines

Follow these general guidelines before performing a software upgrade:

Review the nondisruptive upgrade path to release 5.2(2) in Table 11.

Install and configure dual supervisor modules before the upgrade.

Issue the show install all impact upgrade-image CLI command to determine if your upgrade will be nondisruptive.

Be aware that some features impact whether an upgrade is disruptive or nondisruptive:

Fibre Channel Ports: Fibre Channel ports can be nondisruptively upgraded without affecting traffic on the ports. See Table 11 for the nondisruptive upgrade path for all NX-OS and SAN-OS releases.

Gigabit Ethernet Ports: Traffic on Gigabit Ethernet ports is disrupted during an upgrade or downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MSM-18/4 module and the MDS 9222i switch. Those nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the upgrade is in progress.

FICON: If you have FICON enabled, the upgrade path is different. See the "FICON Supported Releases and Upgrade Paths" section.


Note In addition to these guidelines, you may want to review the information in the "Limitations and Restrictions" section prior to a software upgrade to determine if a feature may possibly behave differently following the upgrade.


Nondisruptive Upgrade Paths

Use Table 11 to determine your nondisruptive upgrade path to Cisco MDS NX-OS Release 5.2(2a). Find the image release number you are currently using in the "Current Release" column of the table and follow the steps in the order specified to perform the upgrade.


Note See Table 14 before performing a software upgrade on a Cisco MDS 9509 or 9506 switch to dertermine if the upgrade is disruptive or nondisruptive.



Note The software upgrade information in Table 11 applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and intelligent services traffic.



Caution Upgrading to Cisco NX-OS Release 5.2(2a) without first upgrading to Release 5.0(x) is not recommended and is not supported, and might result in configuration loss. If you are upgrading to Cisco NX-OS Release 5.2(2a) from any release other than Release 5.2(2) or Release 5.2(1) the only supported upgrade path to Release 5.2(2a) is from Release 5.0(x).

Downgrading Your Cisco MDS SAN-OS Software Image

This section lists the guidelines recommended for downgrading your Cisco MDS SAN-OS software image and includes the following topics:

Downgrading Guidelines Specific to NX-OS Release 5.2(2a)

General Downgrading Guidelines

Downgrading Guidelines Specific to NX-OS Release 5.2(2a)

The following guideline applies to a downgrade from Cisco MDS NX-OS Release 5.2(2a):

You cannot nondisruptively downgrade from NX-OS Release 5.2(2a) to NX-OS Release 5.0(x) if you installed NX-OS Release 5.2(2a) on an MDS 9509 or MDS 9506 switch and you installed a Generation 4 module in the switch and performed a full switch reload. The reason for this restriction is the change in fabric mode that occurs following the switch reload with the Generation 4 hardware installed. The downgrade will be disruptive, even if you remove the Generation 4 module prior to starting the downgrade.

If you do not install Generation 4 hardware or perform a full switch reload following the installation of NX-OS Release 5.2(2a) on an MDS 9509 or MDS 9506 switch, then you can nondisruptively downgrade to NX-OS Release 5.0(x).

We recommend that you delete any SPAN configuration, Fibre Channel tunnel, or tunnel-ID map configuration from your switch before you downgrade from NX-OS Release 5.2(2a) to a lower version. If any SPAN session, SPAN destination, SPAN target, or Fibre Channel tunnel interface is configured, the installer should detect it and prompt you to delete these configurations.

To gather information about SPAN sessions and delete them, use the following commands in this order:

show incompatibility systems bootflash:image_name to display any incompatible configurations

show span session to check the current configuration for a SPAN session

no span session session-number to delete a SPAN session

show running-config | include fc-tunnel to check the current Fibre Channel tunnel configuration

no interface fc-tunnel y to delete a Fibre Channel tunnel on the switch that is the source for the Fibre Channel tunnel

show interface brief | include SD to check the current configuration for a SPAN destination port configuration

show interface brief | include ST to check the current configuration for a SPAN target port configuration

no fc-tunnel tunnel-map z interface x/y to remove an Fibre Channel tunnel map

no switchport mode sd to negate the SPAN destination port mode for the SPAN destination port

no switchport mode st to negate the SPAN target port mode for the SPAN target port

General Downgrading Guidelines

Follow these general guidelines before you perform a a software downgrade:

Issue the system no acl-adjacency-sharing execute command to disable ACL adjacency usage on Generation 2 and Generation 1 modules. If this command fails, reduce the number of zones, IVR zones, TE ports, or a combination of these in the system and issue the command again.

Disable all features not supported by the downgrade release. Use the show incompatibility system downgrade-image command to determine what you need to disable.

Use the show install all impact downgrade-image command to determine if your downgrade will be nondisruptive.

Be aware that some features impact whether a downgrade is disruptive or nondisruptive:

FCoE: Fibre Channel over Ethernet requires Cisco NX-OS Release 5.2(x). A downgrade from Release 5.2(x) disrupts and stops all FCoE traffic.

Fibre Channel Ports: Fibre Channel ports can be nondisruptively downgraded without affecting traffic on the ports. See Table 15 for the nondisruptive downgrade path for all SAN-OS releases.

Gigabit Ethernet Ports: Traffic on Gigabit Ethernet ports is disrupted during a downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MSM-18/4 module, and the MDS 9222i switch. Those nodes that are members of VSANs traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the downgrade is in progress.

FICON: If you have FICON enabled, the downgrade path is different. See the "FICON Downgrade Paths" section.

Software support for the MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) module

The MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) module is a multihop-capable FCoE module for the core data center. This full line-rate FCoE module for the MDS 9500 Series Director switches allows you to extend FCoE benefits beyond the access Layer into the data center core. FCoE supports I/O consolidation by preserving all Fibre Channel constructs, and maintaining the same latency, security, and traffic management attributes of Fibre Channel. In addition, FCoE extends Fibre Channel SAN connectivity to Cisco Nexus 7000 switches that are FCoE capable.

Software support for Cisco MDS 9000 Family 8-Gbps Advanced Fibre Channel Switching Modules

Cisco NX-OS Release 5.2(1) includes software support for the 32-port and the 48-port 8-Gbps Advanced Fibre Channel switching modules that can be used in the MDS 9500 Series Directors. The MDS 9513 Multilayer Director can be upgraded with the new Generation 4 Fabric-3 module to increase bandwidth to 256 Gbps per slot. In addition, the 8-Gbps Advance Fibre Channel switching module support speeds of 10 Gbps on the MDS 9513 with the Fabric-3 module installed. The upgrade from the Fabric-2 module to the Fabric-3 module is nondisruptive.

Cisco MDS 9000 8-Gbps Advanced Fibre Channel switching modules support Cisco FlexSpeed technology that enables ports to be configured as either 1-, 2-, 4-, or 8-Gbps, or 10-Gbps Fibre Channel interfaces.

Cisco MDS 9000 8-Gbps Advanced Fibre Channel switching modules support Arbitrated Local Switching to locally switch traffic at line rate 8-Gbps in a fair manner across all ports on the module through central arbitration.

Storage Media Encryption for Disk

The Storage Media Encryption (SME) solution, which currently protects data at rest on heterogeneous tape drives and virtual tape libraries (VTLs), has been enhanced to encrypt data on disk arrays in a SAN environment using secure IEEE-standard Advanced Encryption Standard (AES) algorithms.

SME Disk requires the Storage Media Encryption Package license.

See the Cisco MDS 9000 Family Storage Media Encryption Configuration Guide for more information on configuring and deploying SME Disk.

Cisco Data Center Network Manager for SAN

Cisco Fabric Manager and Cisco Data Center Network Manager have merged into a unified product that can now manage and monitor both SAN and LAN environments. As a part of this merger, Cisco Fabric Manager has been rebranded as Cisco DCNM for SAN.

As a part of NX-OS Release 5.2(1), Cisco DCNM for SAN introduces server-based licenses that allow you to purchase a pool of Cisco DCNM for SAN licenses instead of a switch-based Fabric Manager Server (FMS) license. The installed base of existing FMS licenses are grandfathered into Cisco DCNM for SAN, which means that you do not have to purchase a new license to use Cisco DCNM for SAN if you have an existing FMS license.

There are many new features in Cisco DCNM for SAN, including:

Summary and host dashboards

VMware topology and performance

Performance forecasting charts

External SMI-S 1.4 agent

FCoE provisioning and management

Detailed information about Cisco DCNM features is available in the Cisco DCNM Release Notes, Release 5.2, and in the feature configuration guides for Cisco DCNM for SAN.

For additional information about Cisco MDS NX-OS Release 5.2(1), see the Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(1).

New Hardware in Cisco MDS NX-OS Release 5.2(1)

Cisco MDS NX-OS Release 5.2(1) supports the following new Generation 4 hardware devices:

Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) module (DS-X9708-K9)

Cisco MDS 9000 32-port 8-Gbps Advanced Fibre Channel Switching module (DS-X9232-256K9)

Cisco MDS 9000 48-port 8-Gbps Advanced Fibre Channel Switching module (DS-X9248-256K9)

Cisco MDS 9513 Switching Fabric 3 module (DS-13SLT-FAB3)

See the Cisco MDS 9500 Series Hardware Installation Guide for descriptions of, and specifications for the new Generation 4 modules. This guide also provides instructions for migrating to the new Fabric 3 module and guidelines for installing the new 8-Gbps Advanced Fibre Channel switching modules.

Licensed Cisco NX-OS Software Packages

Most Cisco MDS 9000 family software features are included in the standard package. However, some features are logically grouped into add-on packages that must be licensed separately, such as the Cisco MDS 9000 Enterprise package, SAN Extension over IP package, Mainframe package, Storage Services Enabler (SSE) package, Storage Media Encryption package, and Data Mobility Manager package. On-demand ports activation licenses are also available for the Cisco MDS Blade Switch Series and 4-Gbps Cisco MDS 9100 Series Multilayer Fabric switches.


Note A license is not required to use the Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) module (DS-X9708-K9).


Enterprise Package

The standard software package that is bundled at no charge with the Cisco MDS 9000 Family switches includes the base set of features that Cisco believes are required by most customers for building a SAN. The Cisco MDS 9000 family also has a set of advanced features that are recommended for all enterprise SANs. These features are bundled together in the Cisco MDS 9000 Enterprise package. Refer to the Cisco MDS 9000 Enterprise package fact sheet for more information.

SAN Extension over IP Package

The Cisco MDS 9000 SAN Extension over IP package allows the customer to use FCIP to extend SANs over wide distances on IP networks using the Cisco MDS 9000 family IP storage services. Refer to the Cisco MDS 9000 SAN Extension over IP package fact sheet for more information.

Mainframe Package

The Cisco MDS 9000 Mainframe package uses the FICON protocol and allows control unit port management for in-band management from IBM S/390 and z/900 processors. FICON VSAN support is provided to help ensure true hardware-based separation of FICON and open systems. Switch cascading, fabric binding, and intermixing are also included in this package. Refer to the Cisco MDS 9000 Mainframe package fact sheet for more information.

Storage Media Encryption Package

The Cisco MDS 9000 Storage Media Encryption package enables encryption of data at rest on heterogeneous tape devices, virtual tape libraries, and disk arrays as a transparent fabric service. Cisco SME is completely integrated with Cisco MDS 9000 Family switches and the Cisco DCNM for SAN application, enabling highly available encryption services to be deployed without rewiring or reconfiguring SANs, and allowing them to be managed easily without installing additional management software. Refer to the Cisco MDS 9000 Storage Media Encryption package fact sheet for more information. The Storage Media Encryption package is for use only with Cisco MDS 9000 Family switches.

Data Mobility Manager Package

The Cisco MDS 9000 Data Mobility Manager package enables data migration between heterogeneous disk arrays without introducing a virtualization layer or rewiring or reconfiguring SANs. Cisco DMM allows concurrent migration between multiple LUNs of unequal size. Rate-adjusted migration, data verification, dual Fibre Channel fabric support, and management using Cisco DCNM for SAN provide a complete solution that greatly simplifies and eliminates most downtime associated with data migration. Refer to the Cisco MDS 9000 Data Mobility Manager package fact sheet for more information. The Data Mobility Manager package is for use only with Cisco MDS 9000 Family switches.

Storage Services Enabler Package

The Cisco MDS 9000 SSE package allows network-based storage applications and services to run on the Cisco MDS 9000 family SSMs, Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4), and Cisco MDS 9222i. Intelligent fabric applications simplify complex IT storage environments and help organizations gain control of capital and operating costs by providing consistent and automated storage management. Refer to the Cisco MDS 9000 SSE package fact sheet for more information.

On-Demand Port Activation License

On-demand ports allow customers to benefit from Cisco NX-OS Software features while initially purchasing only a small number of activated ports on 8-Gbps or 4-Gbps Cisco MDS 9100 Series Multilayer Fabric switches. As needed, customers can expand switch connectivity by licensing additional ports.

I/O Accelerator Package

The Cisco I/O Accelerator (IOA) package activates IOA on the Cisco MDS 9222i fabric switch, the Cisco MDS 9000 18/4 Multiservice Module (MSM-18/4), and on the SSN-16 module. The IOA package is licensed per service engine and is tied to the chassis. The number of licenses required is equal to the number of service engines on which the intelligent fabric application is used.The SSN-16 requires a separate license for each engine on which you want to run IOA. Each SSN-16 engine that you configure for IOA checks out a license from the pool managed at the chassis level. SSN-16 IOA licenses are available as single licenses.

XRC Acceleration License

The Cisco Extended Remote Copy (XRC) acceleration license activates FICON XRC acceleration on the Cisco MDS 9222i switch and on the MSM-18/4 in the Cisco MDS 9500 Series directors. One license per chassis is required. You must install the Mainframe Package and the SAN Extension over FCIP Package before you install the XRC acceleration license. The Mainframe Package enables the underlying FICON support, and the FCIP license or licenses enable the underlying FCIP support.

Deprecated Features

Cisco MDS NX-OS Release 5.2 no longer supports the features listed in the following sections:

Zoning Features

SNIA Common Information Model

IVR Non-NAT Mode

Zoning Features

LUN zoning, read-only zones, and broadcast zones are no longer supported. These features affect the following hardware:

Cisco MDS 9000 8-port 10-Gbps Fibre Channel over Ethernet (FCoE) module

Cisco MDS 9000 48-port 8-Gbps Advanced Fibre Channel Switching module

Cisco MDS 9000 32-port 8-Gbps Advanced Fibre Channel Switching module

You cannot bring up these modules if these features are already configured. You should completely remove all configurations that include these features before you attempt to bring up these modules. In addition, you cannot configure these features after you bring up these modules.

SNIA Common Information Model

SNIA Common Information Model (CIM or cimserver) commands are no longer supported. CIM is supported in Cisco DCNM-SAN Release 5.2. The SMI-S agent that is installed on the Cisco DCNM-SAN server allows external application to access fabric and switch profiles as specified in SNIA CIM. For additional information, see the Cisco DCNM Release Notes, Release 5.2.

IVR Non-NAT Mode

IVR non-NAT mode is not supported in Cisco NX-OS Release 5.2(x). If you have IVR non-NAT mode configured, see the "Upgrading Guidelines Specific to NX-OS Release 5.2(2a)" section for instructions on how to migrate to IVR NAT mode before upgrading to Cisco NX-OS Release 5.2(2a).

Limitations and Restrictions

This section lists the limitations and restrictions. The following limitations are described:

FCoE Module

IPv6

User Roles

Schedule Job Configurations

Maximum Number of Zones Supported in Interop Mode 4

InterVSAN Routing

Java Web Start

VRRP Availability

Using a RSA Version 1 Key for SSH Following an Upgrade

CFS Cannot Distribute All Call Home Information

Availability of F Port Trunking and F Port Channels

Reserved VSAN Range and Isolated VSAN Range Guidelines

Applying Zone Configurations to VSAN 1

Running Storage Applications on the MSM-18/4

RSPAN Traffic Not Supported on CTS Ports on 8-Gbps Switching Modules

I/O Accelerator Feature Limitations

Support for FCIP Compression Modes

Saving Copies of the Running Kickstart and System Images

Configuring Buffer Credits on a Generation 2 or Generation 3 Module

Features Not Supported on the Cisco MDS 9148 Switch

PPRC Not Supported with FCIP Write Acceleration

Configuring a Persistent FCID in an IVR Configuration with Brocade Switches

FCoE Module

In Cisco MDS NX-OS Release 5.2(x), you cannot install a FCoE module in a switch that is running DMM, SME, or IOA.

Link traps for FCoE devices are sent only when a VFC interface flaps.

IPv6

The management port on Cisco MDS switches supports one user-configured IPv6 address, but does not support auto-configuration of an IPv6 address.

User Roles

In SAN-OS Release 3.3(x) and earlier, when a user belongs to a role which has a VSAN policy set to Deny and the role allows access to a specific set of VSANs (for example, 1 through 10), the user is restricted from performing the configuration, clear, execute, and debug commands which had a VSAN parameter outside this specified set. Beginning with NX-OS Release 4.1(1b), these users are still prevented from performing configuration, clear, execute, and debug commands as before, however, they are allowed to perform show commands for all VSANs. The ability to execute the show command addresses the following:

In a network environment, users often need to view information in other VSANs even though they do not have permission to modify configurations in those VSANs.

This behavior makes Cisco MDS 9000 Series switches consistent with other Cisco products, such as Cisco Nexus 7000 Series switches, that exhibit the same behavior for those roles (when they apply to the VLAN policy).

Schedule Job Configurations

As of MDS NX-OS Release 4.1(1b) and later, the scheduler job configurations need to be entered in a single line with a semicolon(;) as the delimiter.

Job configuration files created with SAN-OS Release 3.3(1c) and earlier, are not supported. However, you can edit the job configuration file and add the delimiter to support Cisco NX-OS Release 4.1(3a).

Maximum Number of Zones Supported in Interop Mode 4

In interop mode 4, the maximum number of zones that is supported in an active zone set is 2047, due to limitations in the connected vendor switch.

When IVR is used in interop mode 4, the maximum number of zones supported, including IVR zones, in the active zone set is 2047.

InterVSAN Routing

When using InterVSAN Routing (IVR), it is recommended to enable Cisco Fabric Services (CFS) on all IVR-enabled switches. Failure to do so may cause mismatched active zone sets if an error occurs during zone set activation.

Java Web Start

When using Java Web Start, it is recommended that you do not use an HTML cache or proxy server. You can use the Java Web Start Preferences panel to view or edit the proxy configuration. To do this, launch the Application Manager, either by clicking the desktop icon (Microsoft Windows), or type ./javaws in the Java Web Start installation directory (Solaris Operating Environment and Linux), and then select Edit> Preferences.

If you fail to change these settings, you may encounter installation issues regarding a version mismatch. If this occurs, you should clear your Java cache and retry.

VRRP Availability

The Virtual Router Redundancy Protocol (VRRP) is not available on the Gigabit Ethernet interfaces on the MSM-18/4 module or module 1 of the MDS 9222i switch, even though it is visible on these modules. The feature is not implemented in the current release.

Using a RSA Version 1 Key for SSH Following an Upgrade

For security reasons, NX-OS Release 4.2(1b) does not support RSA version 1 keys. As a result, if you upgrade to NX-OS Release 4.2(1b) from an earlier version that did support RSA version 1 keys, and you had configured a RSA version 1 key for SSH, then you will not be able to log in through SSH following the upgrade.

If you have a RSA version 1 key configured for SSH, before upgrading to NX-OS Release 4.1(3a), follow these steps:


Step 1 Disable SSH.

Step 2 Create RSA version 2 DSA keys.

Step 3 Enable SSH.

Step 4 Delete any RSA version 1 keys on any remote SSH clients and replace the version 1 keys with the new version 2 keys from the switch.

Proceed with the upgrade to NX-OS Release 4.2(1b).


If you upgrade before disabling SSH and creating RSA version 2 keys, follow these steps:


Step 1 Open a Telnet session and log in through the console.

Step 2 Issue the no feature ssh command to disable SSH.

Step 3 Issue the ssh key rsa 1024 command to create RSA version 2 keys.

Step 4 Issue the feature ssh command to enable SSH.


CFS Cannot Distribute All Call Home Information

In MDS NX-OS Release 4.2(1b), CFS cannot distribute the following Call Home commands that can be configured with the destination-profile command:

destination-profile profile_name transport-method

destination-profile profile_name http

The output of the show running-config callhome command shows configured Call Home commands:

switch# show running-config callhome
> version 4.1(3)
> callhome
>   email-contact abc@cisco.com <mailto:abc@cisco.com>
>   phone-contact +14087994089

>   transport email from abc@cisco.com <mailto:abc@cisco.com>
>   enable
>   commit 
 
   

When you attempt to apply these commands in the ASCII configuration, the following commands fail:

>   no destination-profile testProfile transport-method email
>   destination-profile testProfile transport-method http
>   destination-profile testProfile http https://xyz.abc.com
 
   

To work around this issue, issue these commands after the commit command.

Availability of F Port Trunking and F Port Channels

Trunking F ports and trunking F port channels are not supported on the following MDS 9000 components:

DS-C9134-K9, Cisco MDS 9134 Multilayer Fabric Switch, if NPIV is enabled and the switch is used as the NPV core switch

DS-C9124-K9, Cisco MDS 9124 Multilayer Fabric Switch, if NPIV is enabled and the switch is used as the NPV core switch

Trunking F ports, trunking F port channels and regular F port channels are not supported on the following MDS 9000 components:

DS-X9016, Cisco MDS 9000 2-Gbps16-Port Fibre Channel Switching Module

DS-X9032, Cisco MDS 9000 2-Gbps 32-Port Fibre Channel Switching Module

DS-X9032-14K9, Cisco MDS 9000 14/2-Port Multiprotocol Services Module (MPS-14/2)

For configuration information, refer to the "Configuring Trunking" section in the Cisco MDS 9000 NX-OS Interfaces Configuration Guide.

Reserved VSAN Range and Isolated VSAN Range Guidelines

On an NPV switch with a trunking configuration on any interface, or on a regular switch where the feature fport_channel_trunk command has been issued to enable the Trunking F PortChannels feature, follow these configuration guidelines for reserved VSANs and the isolated VSAN:

If trunk mode is on for any of the interfaces or NP PortChannel is up, the reserved VSANs are 3040 to 4078, and they are not available for user configuration.

The Exchange Virtual Fabric Protocol (EVFP) isolated VSAN is 4079, and it is not available for user configuration.

The following VSAN IDs are assigned in the Fibre Channel Framing and Signaling (FC-FS) interface standard:

VF_ID Value
Value Description

00h

Do not use as a Virtual Fabric Identifier.

001h ... EFFh

Available as a Virtual Fabric Identifier.

F00h ... FEEh

Reserved.

FEFh

Control VF-ID (see Fibre Channel Link Services (FC-LS) and Fibre Channel Switch Fabric Generation 4 (FC-SW-4) standards).

FF0h ... FFEh

Vendor specific.

FFFh

Do not use as a Virtual Fabric Identifier.

FEFh = 4079

 

Applying Zone Configurations to VSAN 1

In the setup script, you can configure system default values for the default-zone to be permit or deny, and you can configure default values for the zone distribution method and for the zone mode.

These default settings are applied when a new VSAN is created. However, the settings will not take effect on VSAN 1, because it exists prior to running the setup script. Therefore, when you need those settings for VSAN 1, you must explicitly issue the following commands:

zone default-zone permit vsan 1

Running Storage Applications on the MSM-18/4

The Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4) does not support multiple, concurrent storage applications. Only one application, such as SME or DMM, can run on the MSM-18/4 at a time.

RSPAN Traffic Not Supported on CTS Ports on 8-Gbps Switching Modules

An inter-switch link (ISL) that is enabled for Cisco TrustSec (CTS) encryption must be brought up in non-CTS mode to support remote SPAN (RSPAN) traffic on the following modules:

DS-X9248-96K9: Cisco MDS 9000 48-Port 8-Gbps Fibre Channel Switching Module

DS-X9224-96K9: Cisco MDS 9000 24-Port 8-Gbps Fibre Channel Switching Module

DS-X9248-48K9: Cisco MDS 9000 4/44-Port Host-Optimized 8-Gbps Fibre Channel Switching Module

If the ISL link is brought up with CTS enabled, random packets drops of both RSPAN traffic and normal traffic will occur on the receiver port switch.

I/O Accelerator Feature Limitations

IOA does not support the following NX-OS features:

F port trunking

F port channeling

IOA cannot be configured on flows in topologies that have devices with NPV and NPIV enabled. For example, IOA is not supported in a topology where a host logs in from a NPV edge switch and IOA is deployed on a NPV core switch for this host.

Support for FCIP Compression Modes

In Cisco NX-OS Release 4.2(1b) and later, FCIP compression mode 1 and compression mode 3 are not supported on the Cisco MSM-18/4 module and on the SSN-16 module.

Saving Copies of the Running Kickstart and System Images

After you upgrade to MDS NX-OS Release 4.2(1b), you are not allowed to delete, rename, move, or overwrite the kickstart and system images that are in the current system bootvar settings on an active or standby MDS Supervisor-2 module on any Cisco MDS 9500 Series switch. This restriction does not apply to the integrated supervisor module on the MDS 9200 and MDS 9100 series switches.

Configuring Buffer Credits on a Generation 2 or Generation 3 Module

When you configure port mode to auto or E on a Generation 2 module, one of the ports will not come up for the following configuration:

Port Mode: auto or E for all of the ports

Rate Mode: dedicated

Buffer Credits: default value

When you configure port mode to auto or E on a Generation 3 module, one or two of the ports will not come up for the following configuration:

Port Mode: auto or E for the first half of the ports, the second half of the ports, or for all of the ports

Rate Mode: dedicated

Buffer Credits: default value

When you configure port mode to auto or E for all ports in the global buffer pool, you need to reconfigure buffer credits on one or more of the ports. The total number of buffer credits configured for all the ports in the global buffer pool should be reduced by 64.

Features Not Supported on the Cisco MDS 9148 Switch

The Cisco MDS 9148 Multilayer Fabric Switch does not support the following NX-OS features:

Remote Span

Translative loop support

FCC - no generation, quench reaction only

FC-Redirect

In addition, the following features have these limits:

VSANs - 31 maximum

SPAN - 1 session maximum

PPRC Not Supported with FCIP Write Acceleration

IBM Peer to Peer Remote Copy (PPRC) is not supported with FCIP Write Acceleration.

Configuring a Persistent FCID in an IVR Configuration with Brocade Switches

The following information is relevant if you have a fabric that consists of Cisco MDS 9000 switches and Brocade switches, and the Cisco MDS switches are running either NX-OS Release 4.x or Release 5.x and Brocade is running FOS higher than 6.x. In an IVR configuration, when IVR NAT is enabled on a Cisco MDS 9000 switch, the device in the native VSAN should be configured with a persistent FCID. Assuming the FCID is 0xAABBCC, AA should be configured with the virtual IVR domain ID of the VSAN that contains the ISLs and BB should be configured in the following range:

1 through 64 if the Brocade switch is operating in native interop mode.

1 through 30 if the Brocade switch is operating in McData Fabric mode or McData Open Fabric Mode.

This configuration ensures that the devices connected to the Cisco MDS 9000 switch can be seen in the name server database on the Brocade switch.

Resolved Caveats

CSCtw52878

Symptom: A Tivoli Storage Manager (TSM) that is in an IOA flow logs ANR8311E errno=16.

This symptom might be seen when IOA sends a SCSI busy message to the TSM server.

Workaround: This issue is resolved.

CSCtg09415

Symptom: An MDS 9000 Series switch does not inform customers of excessive internal drops.

Workaround: This enhancement request is resolved. The following new counters were added to the port-monitor feature in the counters command and the monitor counters command.

err-pkt-from-port  Configure err-pkt-from-port counter
err-pkt-to-xbar    Configure err-pkt-to-xbar counter
err-pkt-from-xbar  Configure err-pkt-from-xbar counter

Open Caveats

CSCtn72391

Symptom: Following a switch reload or a software upgrade, the startup configuration occasionally does not display feature FCIP.

Workaround: Once the switch is completely up, copy the running configuration to the startup configuration by entering the copy running-config startup-config command.

CSCtr10877

Symptom: Following an ISL flap that isolates some switches in the fabric (and the corresponding FCR peers) and then later merges them again, some FCR peers might get out of sync with the SSM switch FCR peer (that is, the FCR peer that owns a configuration) during the peer discovery phase. Consequently, some application flows might not come online, or might even get deleted.

Workaround: Enter the following supervisor commands on the problematic FCR peer, which will trigger this FCR peer to resync with the rest of the fabric, and force it to come out of the error state:

switch# test fc-redirect config sync-with-fabric 
switch# test fc-redirect config sync-with-fabric all-peers
 
   

If more than one peer is affected by this issue, then additional steps are needed. If the application flows do not come online, then the application CLI commands need to be checked to verify that the flows did not get deleted. If they did, then the flows need to be recreated again through the application CLI command s or Cisco DCNM-SAN interface.

CSCtw64713

Symptom: Occasionally, a 10-G ISL between a 32-port 8-Gbps Advanced Fibre Channel Switching Module (DS-X9232-256K9) or a 48-port 8-Gbps Advanced Fibre Channel Switching Module (DS-X9248-256K9) and an older generation Cisco MDS 9000 module can take a long time to come up. The link can go into an error-disabled state.

Workaround: None.

CSCty32238

Symptom: On certain hardware, certain Cisco MDS 9000 Series features and applications do not work. These include IVR, IOA, DMM, SME, fcflow, and SPAN.

The following devices with hardware revision 1.5 are affected by this issue:

DS-X9248-96K9, 48-port 8-Gbps Fibre Channel Switching Module

DS-X9248-48K9, 4/44-port host-optimized 8-Gbps Fibre Channel Switching Module

DS-X9224-96K9, 24-port 8-Gbps Fibre Channel Switching Module

The following devices with hardware revision 1.0 are affected by this issue:

DS-X9304-18K9, 18/4-Port Multiservice Module (MSM-18/4)
For this module, the affected version is 73-14372-01A0 hardware version 1.0 (due to the new 73-number)

DS-C9222i-K9, Cisco MDS 9222i Multilayer Fabric Switch
For this switch, the affected version is 73-14373-01A0 hardware version 1.0 (due to the new 73-number)

For the DS-X9248-96K9, DS-X9248-48K9 and DS-X9224-96K9 modules, the output of the show module command indicates whether or not the device is affected.

switch# sh mod 2

20:58:00:0d:ec:24:f4:c0 
 
   

In the preceding output, the device is hardware revision 1.0 and therefore not affected.

For the DS-X9304-18K9 and the DS-C9222i-K9, the show module command might indicate hardware version 1.0 due to new part numbers; however the show sprom module command shows the affected parts.

Workaround: Upgrade to software release that has the fix for this issue.

After performing a software upgrade to a Cisco NX-OS release that contains a fix for this issue, it may be necessary to enter the shut command followed by the no shut command on the affected host ports to regain connectivity.

If you perform a nondisruptive upgrade or downgrade from a release that contains a fix to a release that does not contain the fix, you need to reload each module affected by this issue.

If you have a Cisco MDS 9222i swtich that is affected by this issue, and you perform a nondisruptive upgrade or downgrade from a release that contains a fix to a release that does not contain the fix, you need to reload the switch.

CSCty85364

Symptom: Devices on an NPV switch with a trunked uplink to the core NPIV switch lose connectivity to other devices after zone configuration changes.

Conditions: This issue occurs after a zone set activation and only when all of the following conditions are true:

The switch is running NX-OS Release 5.2(1), Release 5.2(2), or Release 5.2(2a)

The F-port on the NPIV switch is located on an MDS 9000 48 port 8-Gbps Advanced Fibre Channel module (DS-X9248-256K9) or on an MDS 9000 32 port 8-Gbps Advanced Fibre Channel module (DS-X9232-256K9).

The F-port carries multiple VSANs.

The zone set activation is for a VSAN that is trunked to the NPV switch.

Workaround: This issue is resolved in NX-OS Release 5.2(2d). However, upgrading to Release 5.2(2d) after you encounter this issue in an earlier 5.2(x) release does not completely resolve the issue; it only prevents the issue from reoccurring.

When you encounter this issue, the ACL TCAM programming is deleted. To recover from this situation, you must restore the communication between the devices by restoring the ACL TCAM programming.

Recovery Steps:

To restore the ACL TCAM programming, do one of the following:

Reload the DS-X9232-256K9 module or DS-X9248-256K9 module.

Enter the shut command followed by the no shut command on the host and target ports that have lost connection.

Reload the hosts that have lost the targets.


Note If you have already upgraded to NX-OS Release 5.2(2d) without completing the recovery steps in Release 5.2(1), 5.2(2), or 5.2(2a), you must complete the recovery steps because the ACL entries that were deleted are not reprogrammed during the ISSU.


Workaround Steps:

If upgrading to NX-OS Release 5.2(2d) is not an option, you can work around this issue by following these steps:

Attach multiple F-ports between the NPV and NPIV switches and allocate one VSAN to each F-port.

Move the F-port uplink to a module that is not a DS-X9248-256K module or a DS-X9232-256K module.

CSCua61044

Symptom: A device that is attached to a Cisco MDS 9000 48-port 8-Gbps Advanced Fibre Channel Switching Module (DS-X9248-256K9) or a Cisco MDS 9000 32-port 8-Gbps Advanced Fibre Channel Switching Module (DS-X9232-256K9) is not able to communicate with other devices.

This symptom occurs only when a port on the DS-X9248-256K9 or DS-X9232-256K9 module is zoned to more than 146 unique devices.

The following errors can be seen in the log of the DS-X9248-256K9 or DS-X9232-256K9 module:

swtich# show process acltcam internal errors
  1) Event:E_DEBUG, length:84, at 359632 usecs after Tue Jun 19 23:34:44 2012
    [109] Program rqst sync failed. Fwd-eng:0(IN) ifIndex: 0x1104000, status:

  2) Event:E_DEBUG, length:65, at 359603 usecs after Tue Jun 19 23:34:44 2012
    [112] Failed: tcamwrapv2_tcam_ssram_write, 155 entries, errno: 28
 
   

Workaround: Reduce the number of devices that this port is zoned to to 146 devices or less, or connect the device that is attached to the Cisco MDS 9000 48-port 8-Gbps Advanced Fibre Channel Switching Module or the Cisco MDS 9000 32-port 8-Gbps Advanced Fibre Channel Switching Module to a different model module.

CSCtq88900

Symptom: In an SME or IOA deployment, if the number of H->T flows that are added exceeds 512, then subsequent disruptive platform events can leave an FCR unable to process interprocess (MTS) messages at a rate fast enough to support the scaled configuration. This situation can cause an MTS-buffers full condition in the FCR, which can result in unpredictable behavior. Some of the resulting errors may be unrecoverable, and may require a disruptive restart of the flows.

Workaround: Use CFS regions if a large number (greater than 512) of application flows need to be configured. CFS regions segment the FCR peer topology into manageable proportions.

CSCtr29423

Symptom: Tape acceleration is not working with the Emulex CNA card. This issue can be seen because the Emulex CNA card uses the same OXID for all fast-path SCSI commands (read/write), which breaks tape acceleration logic for accelerating the read/write IOs.

Workaround: None.

CSCtr50223

Symptom: On the MDS 9513 switch, when an MSM-18/4 module boots up, it sends a request to the supervisor module to mount the modflash on the MSM-18/4 module. If there is a timeout or error in response, the following syslog message displays:

2011 Jul 14 01:18:13 sw-dc5-br2-12 %LC_MNT_MGR-SLOT3-2-LC_MNT_MGR_ERROR: SUP mount 
failed. MTS receive timedout
2011 Jul 14 01:19:06 sw-dc5-br2-12 %PROC_MGR-SLOT3-2-ERR_MSG: ERROR: PID 1144 
(lc_mnt_mgr) exited abnormally, exit status (0xa)
2011 Jul 14 01:19:06 sw-dc5-br2-12 %MODULE-2-MOD_MINORSWFAIL: Module 3 (serial: 
JAE1141ZB43) reported a failure in service lc_mnt_mgr
 
   

This issue might be seen when the supervisor module is unusually busy and cannot process the mount request from the MSM-18/4 module, or the actual mount command on the supervisor takes a long time.

Workaround: Reload the MSM-18/4 module in the same slot/module where the modflash mount failed. A request will be sent to the supervisor to mount the modflash.

CSCtr55608

Symptom: Following the insertion of the 32-port 8-Gbps Advanced Fibre Channel switching module (DSX9232-256K9), the following syslog message is displayed:

2011 Jul 16 05:35:00 emc-9513-II %SYSMGR-STANDBY-3-UNACCEPTABLE_WAIT: Service "r
es_mgr", no response from System Manager after 10 seconds. Terminating.
 
   

This issue might be seen if you enter the no install feature-set fcoe command, then power down the 32-port 8-Gbps Advanced Fibre Channel switching module, and then insert the module again, which triggers the install feature-set fcoe command.

Workaround: None. This is a not an operationally impacting issue because it happens on the standby supervisor, and the standby supervisor can successfully come up in spite of the syslog message.

CSCty97827

Symptom: Host-to-target connectivity across multihop connected switches is lost. The fcping fails between devices through a port channel.

This issue is extremely rare. The conditions for it may be created after a nondisruptive upgrade to Cisco NX-OS Release 5.2(x). However service disruption might not appear immediately on the affected port channel. The next time one or more members of the port channel flap, traffic loss could occur.

To verify if you have the potential to experiene this issue, enter the commands shown in the following examples:

switch# show port-channel internal info interface port-channel 3
 
   
port-channel 3
channel     : 3   <<< channel_id
bundle      : 10  <<< normally, bundle_id = channel_id - 1
ifindex     : 0x4000002
pcport mode : 67108866
admin mode  : on
oper mode   : on
[...]
 
   
switch # show system internal fcfwd pcmap
port-channel 3:
    IfIndex is 0x04000002        <<< last 3 nibbles 
    Bundle-Index is 0x0000000a   <<< last 3 nibbles are not equal
[...]
 
   

Regardless of the last three nibbles of the preceding indexes, this issue has been hit if the following output contains "pcm_reserv_bundle_id:Conflict,rsv a new one..."

switch# show port-channel internal event-history port-channel 1 
29) Event: E_DEBUG at 487974 usecs after Thu Mar 22 19:44:26 2012
pcm_reserve_bundle_id:Conflict,rsv a new one.req_bundle=0x0,resp_bundle=0x1
 
   

Workaround: Flap the affected port channel by entering the shut command followed by the no shut command and confirm that the issue is no longer present. Note that bundle id is not going to change to channel_id-1, but the last 3 nibbles in IfIndex and Bundle-Index should match.

switch# show port-channel internal info interface port-channel 3
 
   
port-channel 3
channel     : 3
bundle      : 10
ifindex     : 0x4000002
pcport mode : 67108866
[...]
 
   
switch# show system internal fcfwd pcmap 
port-channel 3:
    IfIndex is 0x0400000a
    Bundle-Index is 0x0000000a
[...]
