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 10 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 10 Software Release Compatibility

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

NX-OS Release 6.2(1)

NX-OS Release 5.2(x) or later

NX-OS Release 5.2(x) or later

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 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 Cisco MDS NX-OS Release 6.2(1) 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-sf3ek9-kickstart-mz-npe.6.2.1.bin
  • m9500-sf3ek9-mz-npe.6.2.1.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 6.2(1) 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 6.2 , which is available from the following website:

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

General Upgrading Guidelines

Before upgrading your Cisco NX-OS software, you must determine if the following issue has occurred in your switch:

%FLOGI-1-MSG_FLOGI_REJECT_FCID_ERROR after upgrade/switchover
 

An ISSU or ISSD involves a supervisor switchover, so it is very important that you determine if this issue is present before a supervisor switchover occurs. If this issue is detected before the supervisor switchover, the affected interfaces can be restored easily by entering the shutdown and no shutdown command sequence.

The following example shows how to determine if the issue has occurred before a supervisor switchover:

switch# show flogi internal info | i key|Interface | i key p 1
Interface fc4/32: mode[F] [119f000] Mode: F State: UP Vsan: 237
Vsan no:237 Max flogi key:0x1002a(65578) num_fl[0x1]<<<Max flogi key greater than 65535
--
Interface fc6/32: mode[F] [129f000] Mode: F State: UP Vsan: 237
Vsan no: 237 Max flogi key: 0x1(1) num_fl[0x1]
--

Look for the value for a Max flogi key that is greater than 65535.

In the example, the fc4/32 interface has encountered this issue, but the fc6/32 interface is normal.

If you see that an interface has a Max flogi key greater than 65535 before a system switchover, ISSU, or ISSD, you must disable the interface and then reenable it by using the shutdown command followed by the no shutdown command. This process disrupts the devices on the interface that is being shut down. After the devices relogin, the Max flogi key is reset to 1 and you can avoid this issue.

If an install and/or ISSU, or supervisor switchover has occurred, compare the number of devices fabric login (FLOGI) with the number of devices in the Fibre Channel Name Server (FCNS) local database. Enter the show flogi database and the show fcns database local commands and use the CLI outputs for comparison. If the FLOGI database has fewer entries than the FCNS local database, the issue has occurred.

Also, if the following error message appears after an install, ISSU, or supervisor switchover, the issue might bug may have been encountered:

%FLOGI-1-MSG_FLOGI_REJECT_FCID_ERROR: %$VSAN xxx%$ [VSAN xxx, Interface fc4/19: mode[F]] FLOGI rejected - FCID allocation failed with error 0x401b0000.
 

If you observe either of the above situations, open a case with the Cisco TAC.


Note If the Max flogi key value is a large number and is incrementing, it indicates that a device is repeatedly logging in. This situation might be a separate problem that needs further investigation. For assistance, contact the Cisco TAC.


In addition, follow these general guidelines before performing a software upgrade:

  • Review the nondisruptive upgrade path to Release 6.2(1) in Table 15 .
  • 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 15 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 15 to determine your nondisruptive upgrade path to Cisco MDS NX-OS Release 6.2(1). 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 15 applies only to Fibre Channel switching traffic. Upgrading system software disrupts IP traffic and intelligent services traffic.

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:

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:

Fibre Channel Ports : Fibre Channel ports can be nondisruptively downgraded without affecting traffic on the ports. See Table 18 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.

Use Table 18 to determine the nondisruptive downgrade path from Cisco NX-OS Release 6.2(1). Find the NX-OS or SAN-OS image that you want to downgrade to in the To SAN-OS Release column of the table and follow the steps in the order specified to perform the downgrade.


Note The software downgrade information in Table 18 applies only to Fibre Channel switching traffic. Downgrading system software disrupts IP and intelligent services traffic.

Crossbar Switching Fabric Module

The Cisco MDS 9710 Director supports up to six crossbar fabric modules. Designed specifically for the Cisco MDS 9710 Director, each crossbar fabric module is installed vertically at the back of the chassis behind the fan trays.

A minimum of three crossbar fabric modules are required to deliver full line rate and bandwidth for the switch. A fourth crossbar fabric module is required for N+1 protection.

Each crossbar fabric module connects to 8 switching modules and two supervisor modules. In addition, each crossbar fabric module supports four 55-Gbps fabric ports connected to each switching module and one 55-Gbps fabric port connected to each supervisor module.

Supervisor Module

The supervisor module for the Cisco MDS 9710 Director provides control and management functions for the switch and enables high-performance switching. It supports the following features:

  • Nondisruptive software upgrades
  • Stateful process restart and failover
  • Fully redundant operation
  • Support for up to 384 Fibre Channel ports in a single chassis and 1152 Fibre Channel ports in a single rack
  • Support for up to 24 Tbps of Fibre Channel system bandwidth
  • Multipathing based on Fabric Shortest Path First (FSPF)
  • Ability to dynamically reroute traffic in the event of a switch failure

Each supervisor module is half the width of the chassis. Two supervisor modules can be installed side-by-side in a slot.

Power Supplies

The Cisco MDS 9710 Director supports up to eight hot-swappable 3000-W AC power supplies.

Cisco MDS 9000 48-Port, 16-Gbps Fibre Channel Switching Module

Up to eight Cisco MDS 9000 48-Port 16-Gbps Fibre Channel switching modules can be used in the Cisco MDS 9710 Director. These modules are hot-swappable and compatible with 2-, 4-, 8-, 16- and 10-Gbps interfaces, and they support hot-swappable Enhanced Small Form-Factor Pluggable (SFP+) transceivers.

The Fibre Channel switching module has 12 4-port port groups. Each port group is capable of a speed of 64-Gbps in each direction simultaneously. Ports on this switching module support expansion port (E port), fabric port (F port), fabric loop port (FL port), SPAN destination port (SD port), and (TE port) port mode.

Individual ports can be configured with Cisco 16-Gbps,8-Gbps or 10-Gbps shortwave or longwave SFP+ transceivers. Each port supports 500 buffer credits with no additional licensing required. With the Cisco Enterprise Package, up to 4095 buffer credits can be allocated to an individual port.

New Software Features in Cisco NX-OS Release 6.2(1)

This section briefly describes the new software features introduced in Cisco NX-OS Release 6.2(1).

  • Generic Online Diagnostics

Starting with Cisco NX-OS Release 6.2(1), the Cisco MDS 9000 Family supports the generic online diagnostics (GOLD) feature. With online diagnostics, you can test and verify the hardware functionality of a device while the device is connected to a live network. In particular, the online diagnostics help you verify that hardware and internal data paths are operating as designed so that you can rapidly isolate faults.

For more information about this feature, see the Cisco MDS 9000 System Management Configuration Guide at this URL:

http://www.cisco.com/en/US/products/ps5989/products_installation_and_configuration_guides_list.html

  • Enhancement to map LDAP/AD users to Cisco NX-OS roles and allow both local and remote users to use SSH or Telnet.

For more information about this feature, see the Cisco MDS 9000 Security Configuration Guide , at this URL:

http://www.cisco.com/en/US/products/ps5989/products_installation_and_configuration_guides_list.html

  • Command-line interface (CLI) command changes, including the following:

Enhance the clear snmp counters command.

Display ISL related information.

Display a warning messages for a shared port interface when you bring down the port.

Display throughput information for all ports on a line card or ISL or on a switch or chassis.

Provide an estimated time for DMM job completion.

Shorten the show dmm job job-id 50571379 session session_id (1-20) command to show dmm job-id 50571379 session_id 1

Information about the modified CLI commands can be found in the Cisco MDS 9000 Command Reference at this URL:

http://www.cisco.com/en/US/products/ps5989/prod_command_reference_list.html

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, and Data Mobility Manager package. On-demand ports activation licenses are also available for the MDS 9148 48-Port Multilayer Fabric Switch and the Cisco MDS 8-Gb Fabric Switch for HP c-Class Blade System.


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).


Additional information about licensed Cisco NX-OS software packages is available at this URL:

http://www.cisco.com/en/US/partner/products/ps6029/products_data_sheets_list.html

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.

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.

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 the MDS 9148 48-Port Multilayer Fabric Switch and the Cisco MDS 8-Gb Fabric Switch for HP c-Class Blade System. 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 and Changed Features

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
  • Cisco MDS 9000 48-port 16-Gbps 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.

In addition, the following software features are not supported or are changed in Cisco MDS NX-OS Release 6.2(5a):

The following software features are not supported or are changed in Cisco MDS NX-OS Release 6.2(1):

  • Fibre Channel Redirect (FCR) is currently not supported on the Cisco MDS 9710 Director, but continues to be supported on other Cisco MDS 9000 Family devices.
  • Fibre Channel Redirect on FCoE for Data Mobility Manager – support for moving data from an FC to an FCoE target is currently not supported.
  • Fibre Channel Security Protocol (FC-SP) is currently not supported on the Cisco MDS 9710 Director.
  • Local switching is not supported on the Cisco MDS 9710 Director, but continues to be supported on the Cisco MDS 9500 Series.
  • Online Health Management System (OHMS) – The Generic Online Diagnostics (GOLD) system provides diagnostics for the Cisco MDS 9710 Director instead of the OHMS. In Cisco NX-OS Release 6.2(1), the GOLD system does not provide any support for automation of corrective actions such as rebooting modules based on error thresholds.

Cisco NX-OS Release 6.2(1) does not support the following hardware:

  • Cisco MDS 9134 Fabric Switch
  • Cisco MDS 9124 Fabric Switch
  • Cisco MDS 4-Gbps Fabric Switch for HP c-Class BladeSystem
  • Cisco MDS 4-Gbps Fabric Switch for IBM BladeCenter

Limitations and Restrictions

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

FCoE on the Cisco MDS 9710 Director

The Cisco MDS 9710 Director does not support FCoE. However, the following command-line interface (CLI) commands display information about FCoE, even though the FCoE functionality does not work on the Cisco MDS 9710 switch:

  • The show feature-set command shows fcoe feature-set enabled.
  • The show fcoe command shows FCoE FCF details.
  • In global configuration mode, the fcf argument to the fcoe command can be modified.
  • The vlan vlan-number command allows the VLAN to be created.
  • The show vlan command shows VLAN information.

FCoE vlan-vsan map creation through SNMP is allowed.

FCoE can be enabled or disabled through SNMP.

ASCII File Can Be Copied to the Startup Configuration

The copy bootflash:runnig-config.ascii startup-config command that was deprecated in an earlier Cisco NX-OS release, is enabled in Cisco NX-OS Release 6.2(1).

Fibre Channel Security Protocol (FC-SP) Not Supported

Cisco NX-OS Release 6.2(1) does not support the Fibre Channel Security Protocol (FC-SP) feature only on the Cisco MDS 9710 Director.

Install Module Command Changes

The install module module-number bios command is not supported on the Cisco MDS 9710 switch only in Cisco NX-OS Release 6.2(1) release. Use the install all command to upgrade the bios during a software upgrade.

The install module module-number bios command continues to be supported in Cisco NX-OS Release 6.2(1) on Cisco MDS 9500 Series switches.

Fabric Binding Error Message

When fabric binding is enabled, an error message appears whenever the Mainframe Package license is not installed and also when the grace period is disabled. There is functional impact associated with the error message and the feature is enabled correctly.

Management of Data Mobility Manager by Cisco DCNM

The Data Mobility Manager (DMM) feature has been enhanced to support larger LUN sizes and an increased number of DMM jobs. This enhancement is supported in Cisco DCNM Release 6.2(3) and later releases. The software changes require compatible code versions on the managed switches, and are supported in Cisco MDS NX-OS Release 6.2(1) and later releases.

A DMM infrastructure that does not need these enhancements can continue to be managed with Cisco DCNM Release 6.2(1), or an earlier release. The managed switches must also run a Cisco MDS NX-OS release earlier than Release 6.2(1).

If DMM is not used, the releases of Cisco DCNM and Cisco NX-OS do not need to match.

Resolved Caveats

  • CSCue55653

Symptom : A Cisco MDS 9000 18/4-Port Multiservice Module (DS-X9304-18K9) might reboot during an ISSU or ISSD and cause traffic to be interrupted on Fibre Channel ports on that module and cause the ISSU or ISSD process to stop. The reset reason is “Fatal Module Error” as seen in the following example:

switch# show logging onboard module 4
. . .
Fri Jan 11 16:55:48 2013: Card Uptime Record
----------------------------------------------
Uptime: 15980, 0 days 4 hour(s) 26 minute(s) 20 second(s)
Reset Reason: Reset Requested due to Fatal Module Error (4)
Card Mode..........................: Runtime
 

This issue can only occur during an ISSU or ISSD from Cisco NX-OS Release 5.2(x) software. No other releases are affected.

This issue might occur if both of the following conditions are true:

The compression configuration of an FC IP tunnel changed since the FC IP engine was last reloaded. This change includes modifying existing or newly created FC IP tunnels.

The performance statistics of such an FC IP tunnel are then collected with a tool such as Device Manager. These steps cause extra memory on the module to be consumed, but that memory is required for the ISSU or ISSD.

The preconditions of an ISSU or ISSD failure are satisfied when the 4th column of the following command shows less than 26500 blocks available:

slot <DS-X9304-18K9_slot_#> show system internal flash | include roots
 

Workaround : This issue is resolved.

  • CSCue92054

Symptom : The IVR feature checks out the SAN_EXT_FCIP license without checking to find out if out if the SAN_EXT_FCIP license is checked out by the FC IP feature in Cisco NX-OS Release 5.2(x).

If the IVR feature is enabled first and it checks out the SAN_EXT_FCIP license, FC IP cannot check out the license.

In Cisco NX-OS software releases earlier than Release 5.2(x), when the FC IP feature was enabled, the FC IP module used the SAN-EXT license. If IVR was enabled after the FC IP feature was enabled, IVR checked to find out if the SAN-EXT license was checked out by another feature. If it was checked out, IVR could be enabled.

In Cisco NX-OS Release 5.2(x), after a switchover or ISSU from an earlier release, IVR checks out the SAN_EXT license, and FC IP cannot use the SAN_EXT license because it is checked out by IVR.

Workaround : This issue is resolved.

  • CSCuf31077

Symptom : Ports on the 24-port, 48-port, or 4/44-port 8-Gbps Fibre Channel switching modules go into a suspended state and packets cannot egress or ingress on the port. This issue can occur on Cisco MDS 9500 Series Directors and Cisco MDS 92221 switches when any of the following modules are installed:

24-port 8-Gbps Fibre Channel switching module (DS-X9224-96K9)

48-port 8-Gbps Fibre Channel switching module (DS-X9248-96K9)

4/44-port Host Optimized 8-Gbps Fibre Channel switching module (DS-X9248-48K9)

Condition : This issue occurs after a nondisruptive upgrade to Cisco NX-OS Release 5.2(6x) or Release 5.2(8), and a link flap occurs on the ports.

Further Problem Description: The main indications of a port exhibiting this issue are the following:

The interface is up, there is an F port, there are zero frames per second in and out, there are output discards, and all B2B credits are remaining.

Logging onboard shows small numbers of OFFLINE and TIMEOUT drops that are incrementing.

Workaround : This issue is resolved.

  • CSCud49969

Symptom : If you enter the isapi health-check command after attaching the Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4), the following error appears:

Memory Status: ERROR
 

Condition : This symptom might be seen after attaching the MSM-18/4 module and entering the isapi health-check command. The output shows “Memory Status: ERROR.”

Workaround : This issue is resolved.

  • CSCub28804

Symptom : An option to send port format registered state change notification (RSCN) upon a zoneset activation is unavailable. The zoneset activation might cause a brief I/O latency and disabling RSCNs might alleviate the problem.

Condition: This issue occurs during the zoneset activation on both AIX and Solaris servers.

Workaround : This issue is resolved.

More inforamation: This change introduced a new CLI configuration command:

[no] zone rscn address-format port vsan vsan

Open Caveats

  • CSCub47799

Symptom: Zone crash or switch reload occurs after renaming an enhanced device-alias.

Condition: This issue applies to the following NX-OS versions or platform combinations only:

The Cisco MDS switches running MDS NX-OS Release 5.2(6), 5.2(6a), 5.2(6b), 5.2(8), 5.2(8a), or 6.2(1).

In addition, the following conditions must be true:

Device-alias is set to enhanced mode by using the device-alias mode enhanced command.

Multiple commands are entered using the same device-alias name before a commit, or a named device-alias is not online at the time the commit is performed.


Note This issue occurs in both zone mode basic and zone mode enhanced.


Workaround: To avoided this issue, group the device-alias commands of the same type together and commit the changes before starting the next type. For example, you must use the device-alias commit command after each and every same type of device-alias action. See the examples below.

Example 1

The following example shows how to delete the Alias2 and rename Alias1 to Alias2:

device-alias rename Alias1 temp_Alias1
device-alias rename Alias2 temp_Alias2
device-alias commit
 

Use the show device-alias session status command to verify the device-alias session status.

device-alias rename temp_Alias1 Alias2
device-alias commit
 

Use the show device-alias session status command to verify the device-alias session status.

If you do not need temp_Alias2, use following commands:

device-alias delete temp_Alias2
device-alias commit
 

The following example shows how to delete the Alias2 and rename Alias1 to Alias2:

Example 2

device-alias delete Alias2
device-alias commit
 
Use the show device-alias session status command to verify the device-alias session status.
 
device-alias rename Alias1 Alias2
device-alias commit
 
Use the show device-alias session status command to verify the device-alias session status.

Note You can use multiple device-alias commands of the same type such as delete, rename, and add in the same batch if the names of all the device-alias that areaffected are unique.


  • CSCug01540

Symptom : The VSH process fails when the line length is greater than 471 characters.

Workaround : None.

  • CSCug13649

Symptom : Bootflash files cannot be copied from the switch to the TFTP server using Device Manager.

This symptom might be seen on the Cisco MDS 9513. When it occurs, SNMP immediately returns 14 (deviceBusy). When it occurs on the Cisco MDS 9710, SNMP immediately returns 2 (success).

Workaround : Copy the bootflash files from the switch to the TFTP server for Cisco MDS 9500 Series switches and the Cisco MDS 9710, as in the following example.

Usage for bootflash://

switch# copy bootflash:rcfg tftp://10.106.177.220/test
Trying to connect to tftp server......
Connection to server Established. Copying Started.....

  • CSCug22090

Symptom : When an ISSU occurs from Cisco NX-OS Release 5.2(6b) to Release 6.2(1), LLDP command-line interface (CLI) commands are not available. In this situation, LLDP is running and traffic is flowing normally even after the ISSU, but the CLI commands are not available.)

This symptom might be seen when feature-set fcoe was enabled on the original image, and feature lldps commands were working in the original image. Following the ISSU to Cisco NX-OS Release 6.2.1 image, the commands are not available.

Workaround : Following the ISSU, enter the feature lldp command on the switch to make the LLDP commands available on the switch.

switch(config)# feature lldp
switch(config)# show lldp ?
 
  • CSCug25141

Symptom : The power consumption displayed in the output of the show environment power command is different than the actual power consumption. The command output shows a higher value than the actual value.

This symptom might be seen under normal operating conditions for the Cisco MDS 9710 switch.

Workaround : None.

  • CSCum21081

Symptom: When Cisco MDS switches are upgraded to or running Cisco MDS NX-OS Software Release 6.2(1) or 6.2(3), the Fibre Channel over IP (FCIP) tunnel throughput is reduced considerably. Devices that use these FCIP tunnels might experience latency issues and application outages.

Condition: This issue applies to FCIP tunnels on 16-Port Storage Services Node (SSN16) (DS-X9316-SSNK9) modules only.

Workaround: You must upgrade to Cisco MDS NX-OS Release 6.2(5).

More Information: This issue not seen on Cisco MDS 9000 Family 18/4-Port Multiservice Module (DS-X9304-18K9).

  • CSCuo24658

Symptom: After a switch upgrade to NX-OS 6.2(1) or later, a previously working AAA authenticated user who is configured for non network-operator privileges (such as network-admin) only receives network-operator privileges. This user is no longer able to configure the switch via CLI or SNMP.

The CLI user will show as having 'network-operator' role:

switch# show user-account fieldsupport
user:fieldsupport
roles:network-operator

 

If the SNMP user exists, it will show as having 'network-operator' role:

switch# show snmp user fieldsupport
______________________________________________________________
SNMP USERS
______________________________________________________________
User Auth Priv(enforce) Groups
____ ____ _____________ ______
fieldsupport md5 des(no) network-operator
 

Condition: This issue only affects logins that meet all of the following conditions:

1) are logins to MDS switches

2) are authenticated remotely via RADIUS

3) have multiple vendor-specific attributes (VSAs) defined as a single Cisco-AV Pair, for example, shell and SNMP version 3 settings:

shell:roles="operations-user fieldsupport" snmpv3:auth=SHA priv=AES-128
 

This issue does not occur if the 'shell:roles' VSA is defined alone (even with multiple roles assigned).

Workaround: On the AAA server, create a separate RADIUS policy for NX-OS 6.2(x) users that splits Cisco-AV Pairs into true attribute pairs. For example:

Cisco-AVPair #1: shell:roles="operations-user fieldsupport
Cisco-AVPair #2: snmpv3:auth=SHA priv=AES-128
 

Assign this policy conditionally on the requesting RADIUS client IP address (that is, a Cisco MDS switch mgmt0 IP address). Continue to use the original policy with the old format for RADIUS authentication requests from switches running NX-OS earlier than 6.2(1).

If the RADIUS server does not support conditional assignment of policies by RADIUS client IP address then an alternate method is possible. Create a local user on the switch with local role assignment which will override the remotely supplied role using the following commands:

switch(config)# no username <userid>
switch(config)# username <userid> password ! role fieldsupport
 

Further Problem Description: This issue was introduced in NX-OS release 6.2(1) due to changes to make RADIUS VSA handling consistent across NX-OS platforms.

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.

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

Workaround : None.

  • CSCub40020

Symptom: After an In Service Software Upgrade (ISSU), In Service Software Downgrade (ISSD), or supervisor switchover, devices fail to FLOGI into the switch, and the following error is logged in the syslog:

%FLOGI-1-MSG_FLOGI_REJECT_FCID_ERROR after upgrade/switchover

Condition: This situation occurs if one or all of the following occur:

1. The Max flogi key is greater than 65535. The key can get this high if there are repeated FLOGIs on an interface. After the key exceeds 65535, this issue occurs. However, this situation does not impact end devices.

2. If a supervisor switchover, such as ISSU, ISSD, or system switchover occurs when the key is greater than 65535, Fibre Channel Identifiers (FC IDs) can be dropped from the FLOGI table. The end devices continue to function normally until they are logged out and then attempt to relogin.

3. If after both 1 and 2 above have occurred and then an end device is rebooted on the affected interface, that end device might not be able to log back in.

Workaround: You must first resolve the issue with the device on the interface with the Max flogi key over 65535, such as FLOGI rejects or port security, to prevent the FLOGI key from incrementing.

If the Max flogi key value is greater than 65535 before any supervisor switchover, ISSU, or ISSD, use the shutdown and then no shutdown command on the interface. Consequently, the Max flogi key value must be checked before any supervisor switchover. However, if the supervisor switchover has already occurred and logging in are failing, you must follow either of these steps:

Contact Cisco TAC to implement a nondisruptive recovery. This requires special files not accessible to customers.

Suspend the VSAN and wait for 5 minutes and then unsuspend the VSAN of the affected devices on the switch. This action is disruptive to all devices in that VSAN connected to this switch.

More Information: For detailed information about this issue, see the General Upgrading Guidelines.

Symptom : When both the Enterprise Package and the Mainframe Package licenses are installed and the fabric binding feature is enabled, the standby supervisor module goes into a failure state.

Workaround : None.

  • CSCuf64822

Symptom : The DCBX local information shows LLS DCBX registration when a port is in the shut state:

Local DCBXP Control information:
Operation version: 00 Max version: 00 Seq no: 1 Ack no: 0
Type/
Subtype Version En/Will/Adv Config
006/001 000 Y/N/Y 80
 

In this example 006/001 is the LLS TLV.

Usually all the other DCBX features are deregistered on a port down and this symptom is not seen in the DCBX output. However, the LLS is not deregistered when a port is shut, and therefore it keeps appearing in the output.

Workaround : None.

Symptom : If beaconing is configured on some ports, they might stop blinking after a supervisor switchover or module reload.

This symptom might be seen following a supervisor switchover or module reload.

Workaround : None

  • CSCuf35479

Symptom : The “Bad IPv6 host address” error appears when the snmp-server hostname is configured instead of the IP address. This issue occurs when the domain name and the name-server IP address are configured.

Workaround : Configure the IP addresses instead of the host name.
