Determining the Software Version


Note We strongly recommend that you use the latest available software release supported by your vendor for all Cisco MDS 9000 Family products.


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

To determine the version of the Cisco SAN-OS software currently running on a Cisco MDS 9000 Family switch using the Fabric Manager, from the Switches tab in the information pane, locate the switch using its IP address, logical name, or WWN, and then check its version in the Release column.

Image Upgrade

The Cisco MDS SAN-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.

You can nondisruptively upgrade to (or downgrade from) Release1.3(6) using any Cisco MDS SAN-OS software release other than Release 1.0(2a).


Note Refer to the Determining Software Compatibility section of the Cisco 9000 Family Configuration Guide for more details.

Resolved Caveats

CSCeg13762

Symptom: A license installation failure occurs on the Cisco MDS 9216A switch running Cisco SAN-OS software releases 1.3(2a), 1.3(4a) and 1.3(5).

Workaround: Upgrade to Cisco SAN-OS software releases 1.3(6), 2.0(1b) or later for successful license installation. If desired, the Cisco MDS 9216A switch can then be downgraded to releases 1.3(2a), 1.3(4a), or 1.3(5).

CSCef65409

Symptom: SNMP daemon crashes periodically on a Cisco MDS 9000 Family switch running Release 1.3(4a). Issue the show process memory | include snmp commands at regular intervals to show the pattern of a memory increase.

Workaround: Upgrade to Cisco MDS SAN OS Release 1.3(6).

CSCeg18886

Symptom: If multiple "get all next" queries are sent before receiving a response from the first one, some queries might be dropped as they overwhelm the name server buffers. Some arrays do this to improve performance, resulting in dropped queries.

Workaround: Upgrade to Cisco MDS SAN-OS Release 1.3(6).

Open Caveats

CSCeg33121

Symptom: A small amount of memory in the IP configuration process leaks each time any of the following commands execute: show running-config, show startup-config, copy running-config startup-config. After repeated occurrences, the command fails to execute.

Workaround: None.

CSCed57251

Symptom: In some rare instances in Cisco MDS SAN-OS Release 1.3, 2.0, and 2.1(1), when the IP Storage Services (IPS) module restarted after a failure, VSAN membership information about iSCSI interfaces was lost. However, a configuration saved with the copy running-config startup command was not lost.

Workaround: None.

CSCef83504

Symptom: The system does not recognize a CLI password containing the "$" character.

Workaround: Change your password to a different string that does not include the "$" character. For an admin user-account, you might have to perform the password-recovery procedure to reset the password.

CSCeg23889

Symptom: License warning notifications, either through Call Home or system messages, might occur in the following situations:

The grace period for a license package was triggered (a feature licensed by that license package had been used). Currently none of the features licensed by this license package are enabled.

The grace period for a license package expired. None of the features licensed by this license package are enabled.

Workaround: None.

CSCeg84871

Symptom: When an iSCSI initiator logs in to a Gigabit Ethernet port number 1 on an IPS module in slot 1, the switch sends a login response with the value of the Target Session Identifying Handle (TSIH) field set to zero (0), which is an iSCSI protocol violation. This situation can also occur when an iSCSI initiator logs in to Ethernet PortChannel number 1. The Qlogic iSCSI initiator may verify the TSIH value and reject it.

Workaround: None.

CSCeh61610

Symptom: FCIP Write Acceleration does not work with certain storage replication subsystems.

Workaround: None.

CSCei25319

Sympton: An error message in the log file occurs because the platform manager component passes the wrong parameter while responding to a SNMP query. In some cases, this results in the query not being responded to.

Workaround: Perform a refresh on Device Manager to clear the problem.

CSCsh27840

Symptom: While using an FCIP link for remote SPAN, it is possible that the FCIP link may flap.

Workaround: Do not use FCIP links for Remote SPAN.

CSCec31365

Symptom: When IVR is enabled, the Fabric-Device Management Interface information is not transferred across VSANs for IVR devices.

Workaround: None.

CSCed14920

Symptom: During a switch upgrade, a SAN Volume Controller (SVC) node may not save its entire state under rare circumstances. After the switch upgrades, the node is not part of the cluster. Verify this symptom by issuing the show nodes local command at the svc-config prompt—the command output displays the following information:

The cluster state of the affected SVC node is unconfigured.

The node state of the affected SVC node is free.

Workaround: Manually remove the SVC node from the cluster and then add the node back into the cluster. Refer to Cisco MDS 9000 Family SAN Volume Controller Configuration Guide for procedural details.

CSCed20053

Symptom: On rare occasions, the install license command may fail due to the saved state of the switch configuration. This may occur after saving a remote configuration to the switch using the copy remote-url start-up command.

Workaround: Issue the copy ru st command. The install license command should work properly after that.

CSCef70000

Symptom: If you downgrade from Cisco MDS SAN-OS Release 1.3(5) to Release 1.3(4), then you might lose your per-VSAN in-order delivery configuration.

Workaround: Reconfigure your system with the per-VSAN in-order delivery configuration.

CSCeg56197

Symptom: Configuring the CIM server certificate as listed below might cause your switch to crash.

a. Create a self-certified key (xxxxxx.pem file) on an external server (we use a utility under Hi-Command).

b. Enter conf t to enter configuration mode.

c. Enter cimserver certificate xxxxxx.pem to install a certificate specified in the file named with a .pem extension.

d. Enter cimserver enablehttps to enable HTTPS (secure protocol).

e. Enter cimserver enable to enable the CIM server.

f. Enter Ctrl-z to quit

Workaround: None

CSCeg61535

Symptom: The Telnet server may not be disabled even if you disable it through setup. A telnet session will still work in the switch.

Workaround: Issue the no telnet server enable command in configuration mode to disable telnet after you login to the switch.

CSCeg66225

Symptom: Password recovery might fail if you use the copy <config-url> startup command to save the switch configuration, or if you boot a system image that is older than the image you used to store the configuration and did not use the install all command. The following message might display in syslog or on the console during the process of password recovery.

<<%ASCII-CFG-2-ACFG_CONFIGURATION_APPLY_ERROR>>

Workaround: Issue the write erase command from the switchboot prompt.


Note Using the write erase command will erase the configuration. You must reapply the configuration, if externally stored, after the switch login.


CSCeh21199

Symptom: If the NetApp file server appliance is configured as an initiator performing a Network Data Management Protocol (NDMP) backup, then the fabric login (FLOGI) process on the MDS switch might terminate because of excessive LSTS requests.

This might happen if your N port or NL port uses extended link services to manage and control a public remote loop. The NetApp file server appliance configuration uses these services, namely LSTS and LINIT, which are documented in the Fibre Channel standards compliance (FC-FLA standard) specification.

Workaround: Upgrade to Cisco MDS SAN-OS Release 2.0(4).

CSCeh64080

Symptom: Following an upgrade from Release 1.1 to Release 1.3 or higher, with persistent FC ID enabled, the FC IDs for the storage arrays may get changed after a link flap.

Workaround: None.

CSCei91676

Symptom: If iSCSI virtual targets are configured with more than 50 LUN maps, then erroneous overlapping LUN map system messages appear when the iSCSI initiator is not allowed to log in to these iSCSI virtual targets.

Workaround: Limit the number of configured LUN maps for an iSCSI virtual target to fewer than 50 LUNs.

CSCej08751

Symptom: A Linux host with an iSCSI driver can see only the first eight Logical Units (LUs) of a configured iSCSI virtual target with more than eight LUN maps configured.

Workaround: None.

CSCin81760

Symptom: In some rare cases, license features are disabled when the IP address on a management port is changed.

Workaround: None. Enable the license features again.

CSCsc33788

Symptom: In rare circumstances, after you issue the install all command to upgrade an MDS switch, the upgrade may fail because the installer process fails. When this occurs, you may see a message like the following:

%CALLHOME-2-EVENT: SW_CRASH alert for service: installer
The installer failed to respond for 10 times. Exiting ...
Unable to send exit to installer. Return code -1

If you upgrade from 1.3(x) to 2.1 or from 2.0(x) to 2.1 and the upgrade fails, and if after the upgrade failure the supervisor modules are running the new software version, but some modules are running the older software version, then the next attempt to execute the install all command will trigger this problem.

You should not encounter this problem if you upgrade from 2.1 to a higher version.

Workaround: There are two ways to address this issue:

To non-disruptively upgrade all modules that are running the older software version, issue the install module module-number image command.

To disruptively upgrade the modules, issue the reload module module-number force-dnld command, or reinstall the module.

CSCeh42252

Symptom: If you try to configure SSH key for any of the non-local user- accounts, in some rare cases you might see a core dump on standby.

Workaround: First delete the non-local user-account and create it again so that it becomes a local user-account. Then perform any type of configuration for that user-account. User should not perform configuration operations on non- local user-accounts. Non-local user-accounts can be created due to users getting authenticated using RADIUS/TACACS+ server.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
