Software Download Process

Use the software download procedure to upgrade to a later version, or downgrade to an earlier version, of an operating system. This section describes the software download process for the Cisco MDS NX-OS software and includes the following topics:

Determining the Software Version

To determine the version of Cisco MDS NX-OS or SAN-OS software currently running on a Cisco MDS 9000 Family switch using the CLI, log in to the switch and enter the show version EXEC command.

To determine the version of Cisco MDS NX-OS or SAN-OS software currently running on a Cisco MDS 9000 Family switch using Cisco DCNM for SAN, view the Switches tab in the Information pane, locate the switch using the IP address, logical name, or WWN, and check its version in the Release column.

Determining Software Version Compatibility

Table 7 lists the software versions that are compatible in a mixed SAN environment, the minimum software versions that are supported, and the versions that have been tested. We recommend that you use the latest software release supported by your vendor for all Cisco MDS 9000 Family products.

Table 7 Software Release Compatibility

Cisco NX-OS Software
Minimum NX-OS or SAN-OS Release
Tested NX-OS and SAN-OS Releases

NX-OS Release 5.2(8c)

NX-OS Release 5.0(1a) or later

NX-OS Release 5.0(1a) and later

NX-OS Release 4.2(3) or later

NX-OS Release 4.2(3) and later

SAN-OS Release 3.3(5) or later

SAN-OS Release 3.3(5) and later

Downloading Software

The Cisco MDS NX-OS software is designed for mission-critical high availability environments. To realize the benefits from 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
 

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:


Note Before you begin the upgrade process, review the list of chassis and modules that Cisco MDS NX-OS Release 5.2(8c) 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 Guidelines Specific to NX-OS Release 5.2(8c)

Follow these guidelines when upgrading to Cisco MDS NX-OS Release 5.2(8c):

  • Follow the upgrade path to NX-OS Release 5.2(8c) 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. Cisco MDS DS-X9232-256K9 and DS-X9248-256K9 switching 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 Cisco MDS DS-X9232-256K9 and DS-X9248-256K9 switching modules, 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 Cisco MDS DS-X9232-256K9 and DS-X9248-256K9 switching modules 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(8c)” 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-tunne l 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 reestablish all applications 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(8c) 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(8c). 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 The software upgrade information in Table 11 applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and intelligent services traffic.



Note Before upgrading to Cisco MDS NX-OS Release 5.2(8c) on a Cisco MDS 9509 or 9506 switch, see Table 14 for specific guidelines.



Caution Upgrading to Cisco NX-OS Release 5.2(8c) 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(8c) from any release other than Release 5.2(8b), 5.2(8a), Release 5.2(8), Release 5.2(6b), Release 5.2(6a), Release 5.2(6), Release 5.2(2d), Release 5.2(2a), Release 5.2(2), or Release 5.2(1), the only supported upgrade path to Release 5.2(8c) 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(8c)

The following guidelines apply to a downgrade from Cisco MDS NX-OS Release 5.2(8c):

  • Cisco NX-OS Release 5.2(8c) and later releases support IDLE as a fill word for the switchport fill-pattern command. Releases earlier than Release 5.2(8c) supported only the ARBFF fill word. As a result, when you downgrade from Cisco NX-OS Release 5.2(8c) or a later release to an earlier release that does not support the IDLE fill word, the following syntax error occurs:
Syntax error while parsing 'switchport fill-pattern IDLE speed 8000'
 

The syntax error message is harmless and can be ignored.

  • You cannot nondisruptively downgrade from NX-OS Release 5.2(8c) to NX-OS Release 5.0(x) if you installed NX-OS Release 5.2(8c) 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(c) on an MDS 9509 or MDS 9506 switch, you can nondisruptively downgrade to NX-OS Release 5.0(x).

  • If you have the Storage Media Encryption (SME) application configured on your system, you must delete signature clusters when downgrading from NX-OS Release 5.2(8c) to Release 5.2(1).
  • If smart zoning is enabled on your system and you want to downgrade nondisruptively to a version lower than NX-OS Release 5.2(6), you must disable smart zoning on all VSANs.
  • Following an ISSD from Cisco NX-OS Release 5.2(8c) to an earlier Release 5.2(x) or to Release 5.0(x) on a Cisco MDS 9000 switch that is configured with IVR or FCR, reload the modules with the ELS trap entry. In the case of FCR, reload the module with the FCR device logged in. For IVR, all modules should be reloaded.
  • 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(8c) 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-tunne l 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 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.

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).

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

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(8c)” section for instructions on how to migrate to IVR NAT mode before upgrading to Cisco NX-OS Release 5.2(8).

Limitations and Restrictions

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

SME Quorum

You cannot change the quorum or the SME master node during a master key rekey. If a change occurs during the smart card portion of the operation, the master key rekey operation will fail and must be repeated from the beginning.

OUI Mismatch for SME Tape Targets

If Cisco DCNM does not discover all expected tape targets, check the sme.log to identify an OUI mismatch. Look for a message like the following:

2012.04.09 21:15:50 WARN [SME] skipped target 50:06:0b:00:00:b8:e4:b0 due to explicit type mismatch. Expect: 240 found: 228. If this is an error update your OUI definitions
 

To correct this issue, manually add the OUI definitions to the server.properties file. The format is as follows:

# 0xhhhhhh vendor_name devicetypes h(host)|d(disk)|t(tape)|s(switch)|g(gateway)|m(cisco mds)
# for example: newOUIs=0x00E069 JNI h|d; 0x000ded Cisco m;\
# 0x006069 Brocade s;
newOUIs=

FCIP Performance Drop

FCIP performance can drop in a topology where the round-trip time (RTT) delay is configured at 80 ms, IPsec is enabled, and write acceleration (WA) is not used.

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, we recommend 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 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, clear your Java cache and retry.

VRRP Availability

The Virtual Router Redundancy Protocol (VRRP) is available on the Gigabit Ethernet interfaces on the MSM-18/4 module or module 1 of the MDS 9222i switch.

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 an RSA version 1 key for SSH, then you will not be able to log in through SSH following the upgrade.

If you have an 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 Use the no feature ssh command to disable SSH.

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

Step 4 Use 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>

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, use 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

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 use the following commands:

  • zone default-zone permit vsan 1
  • zoneset distribute full vsan 1
  • zone mode enhanced 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 packet 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
  • DMM
  • SME
  • IOA
  • FCoE

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.

Condition: This issue only occurs only in Cisco MDS DS-X9232-256K9 and DS-X9248-256K9 modules.

Workaround: This issue is resolved.

  • CSCuh48617

Symptom: After an ungraceful failure of the active supervisor in a Cisco MDS 9509 chassis, traffic to or from an MDS DS-X9232-256K9 and DS-X9248-256K9 module is dropped while the supervisor switchover completes with the following syslog messages:

%CALLHOME-2-EVENT: SUP_FAILURE
%MODULE-4-MOD_WARNING: Module 1 (serial: xxxxxxxxxxx) reported warning due to SAC sync lost in device 145 (device error 0xc910026b)
%SYSTEMHEALTH-4-OHMS_MOD_SNAKE_PATH_FAILURE: Snake Loopback data path failure on module 1.
%SYSTEMHEALTH-4-OHMS_MOD_SNAKE_TEST_ERRORS: Snake Loopback test cannot proceed due to internal errors for module 1.
 

Ports on other modules might be affected if they send traffic to the DS-X9232-256K9 or DS-X9248-256K9 modules, and display the following syslog message:

%PORT-5-IF_DOWN_LINK_FAILURE: %$VSAN 2%$ Interface fcx/y is down (Link failure Link Reset failed nonempty recv queue)
 

Condition: This issue only occurs in an MDS 9506 or 9509 chassis with DS-X9232-256K9 or DS-X9248-256K9 modules. This issue is triggered by ungraceful switchovers only; for example, a process failure on the active supervisor causes a High Availability (HA) switchover.

Workaround: This issue is resolved.

  • CSCuj15179

Symptom: An MDS switch gets reloaded and the show system reset-reason command displays the following error:

reset reason for Supervisor-module 1 (from Supervisor in slot 1) ---
1) At 844701 usecs after Thu Aug 29 01:29:45 2013
Reason: Reset Requested by management application

Workaround: This issue is resolved.

  • CSCuh13459

Symptom: An enhancement is required for the show logging onboard command so that it displays clearly denoted CLI output.

Workaround: This issue is resolved.

  • CSCug88985

Symptom: A Cisco MDS switch allocates an area Fibre Channel ID (FCID) instead of a single FCID to a device for a fabric login (FLOGI).

Condition: This issue occurs when one of the conditions is true:

The MDS switch is configured with the following commands:

no fcdomain fcid persistent vsan vsan_number

fcinterop fcid-allocation flat

The host has a port WWN (PWWN) with an organizationally unique identifier (OUI), which is in the default area allocation list. The list of OUIs that get an AREA FCID assigned by default can be retrieved by using the command show fcid-allocation area command.

The MDS running Cisco NX-OS 5.2(8b) or lower version.

Workaround: This issue is resolved.

  • CSCui40517

Symptom: A Cisco MDS Generation 4 module, DS-X9232-256K9 displays speed as Unknown even though the port configuration is Up.

Condition: This issue occurs because of a sync loss.

Workaround: This issue is resolved.

  • CSCuh27347

Symptom: During an In-Service Software Upgrade (ISSU) or In-Service Software Downgrade (ISSD), ports that are administratively Up and also in the not-connected state get reinitialized.

Condition: This issue occurs in all Cisco MDS dual-supervisor switches during a normal operation.

Workaround: This issue is resolved.

  • CSCug79410

Symptom: When all modules are logically removed from the system excluding the active supervisor, the modules might not be detected when they are added again. If the modules are detected, the standby supervisor does not reach the High Availability (HA) status.

Condition: This issue only occurs after a hardware failure with the PM bus on the active supervisor.

Workaround: This issue is resolved.

Open Caveats

  • CSCtr10877

Symptom : Some Fibre Channel Routing (FCR) peers might get out of sync with the master switch FCR peer after an Inter-Switch Link (ISL) flap. This might cause the intelligent application flows not to come online or to get deleted.

Workaround : This issue might occur when using any of the following FCR intelligent applications:

Storage Media Encryption (SME)

I/O Acceleration (IOA)

Data Mobility Manager (DMM)

Workaround: Check the intelligent applications to verify whether any flows are deleted on the problematic switch. If they did, you must recreate flows again through the application CLI or the Cisco Fabric Manager or Cisco Data Center Network Manager (DCNM)-SAN interface.

Enter the following supervisor CLI commands on the problematic FCR switch that triggers it to resync its configuration with the rest of the fabric.

For a single switch, use the following command:

test fc-redirect config sync-with-fabric

If more than one peer is affected by this issue, use the following command:

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

  • 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.

  • CSCty82821

Symptom : After creating an SME cluster, adding disks to a disk group, changing some disk states, and starting the master key rekey, the key creation date is invalid.

Workaround : None.

  • CSCtz40745

Symptom : A “VSAN down” trap is sent for VSAN 4094 when a trunk port goes down even though the VSAN is not configured on the trunk.

This symptom might be seen only when a link down occurs on an E, TE, or TF port.

Workaround : Ignore the trap.

  • CSCty47599

Symptom : The master key share fails if crypto cluster configuration changes during process.

Workaround : None.

  • CSCuf82609

Symptom: After an In-Service Software Upgrade (ISSU) on the Cisco MDS 9222i switch, Cisco Fabric Services (CFS) merge is initiated.

Condition: This issue only occurs on fabric switches (non-director class switches) that are part of a very large fabric.

Workaround: None.

More information: This is a known issue with the CompactFlash card.

  • CSCug67068

Symptom: On Cisco MDS 9148 and MDS 9134 switches, an attempt to overwrite a file fails with the following error:

Permission denied
 

Condition: This issue occurs if a previous attempt to copy to a file with the same name failed.

Workaround: None.

  • CSCuf82609

Symptom: After changing the device alias configuration, the I/O Accelerator (IOA) flows remain unchanged until the reactivation of the zone set.

Condition: This situation occurs during a device-alias add, delete, or rename operation.

Workaround: None.

  • CSCug14122

Symptom: The interface manager (ifmgr) might crash during an In Service Software Upgrade (ISSU).

Condition: This situation occurs when you perform a downgrade to Cisco NX-OS 5.2(8c) from a higher version.

Workaround: This issue is resolved.

  • CSCuh37423

Symptom: After changing the device alias configuration, the I/O Accelerator (IOA) flows remain unchanged until the reactivation of the zone set.

Condition: This situation occurs during a device-alias add, delete, or rename operation.

Workaround: None.

  • CSCuh49283

Symptom: One of the following symptoms are observed:

A zone member goes offline.

A Registered State Change Notification (RSCN) is not sent to zoned members.

The device-mapping entry port world wide name (pWWN) associated to a device alias is not displayed in the Dynamic Port VSAN Membership (DPVM) database.

The show running-configuration ivr command does not display the changes when a device alias member in an Inter-VSAN routing zone (IVR zone) is renamed.

The port world wide name (pWWN) associated with the device alias is found dissociated in the port security database.

A device alias member is not found in the port security database.

Condition: This situation occurs when all or one of the conditions is met:

A user attempts to perform a device-alias operation in batch, such as:

• Renaming an offline device alias to an existing online device alias or vice versa.

• Multiple commands are entered using the same device-alias name before a commit.

A device alias was renamed.

A device alias was deleted and an existing device alias is renamed to the deleted device alias in the same commit.

A device alias, which is not configured, resides in the DPVM database and an online device is renamed to the former.

The IVR distribute option is enabled and the device alias is in enhanced mode, and the changes in a device alias is not updated to the IVR running configuration.

Workaround: Add the offline member to the device alias database, revert to the previous name if you have renamed a device alias, and flap the ports that are connected to the affected zone member.

  • CSCuh57761

Symptom: Multiple port security members that are mapped to a switch WWN (sWWN) logging point are not fully distributed to the peer switches. The following error appears after an Cisco In-Service Software Downgrade (ISSD), followed by entering the port-security commit command:

Internal CLI error: Timer expired
 

Condition: This situation occurs after an ISSD from Cisco MDS NX-OS Release 5.2(8b) to 5.2.(1). After creating and committing port-security entries that map multiple port security members to the same sWWN, all entries are not distributed to the peer switches.

Workaround: None.

  • CSCue31727

Symptom: A user with the priv-14 role does not inherit rules from the priv-0 through priv-13 roles.

Condition: This situation occurs during a normal operation.

Workaround: Create users with roles from priv-0 to priv-13 and log in, or log in to the switch using AAA authentication where users with certain user levels are identified.
