Determining the Software Version
Note We strongly recommend that you use the latest available software release 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, log in to the switch and enter the show version EXEC command.
This Cisco MDS SAN-OS Release 1.0(5) software is packaged in feature sets (also called software images) depending on the platform. The Cisco MDS SAN-OS software feature sets available for the Cisco MDS 9000 Family include Ethernet, Fibre Channel (1 Gbps and 2 Gbps), SNMP, and IP packets.
New and Changed Features in Release 1.0(5)
SAN-OS Release 1.0(5) is a maintenance release for switches in the Cisco MDS 9000 Family. See the "Caveats" section for details on closed and outstanding caveats and limitations.
Note The Release Notes are specific to this maintenance release. For the rest of the 1.0(5) documentation, refer to the Release 1.0(3a) document set (see the "Related Documentation" section).
Standby Supervisor Bootup Alert
If a standby supervisor module fails to bootup, the active supervisor module detects that conditions and generates a Call Home event and a SYSLOG message approximately 3 to 6 minutes after the standby supervisor module moves to the loader> prompt. The following SYSLOG error message is issued:%DAEMON-2-SYSTEM_MSG:Standby supervisor failed to boot up.
This error message is also generated if one of the following situations apply:
•you remain at the loader> prompt for an extended period of time, or
•you do not set the boot variables appropriately.
Update to Configuring Buffer-to-Buffer Credits
All 32-port switching modules have a default value of 12 for the Fx, E, and TE modes. These values cannot be changed.
This is not a new or changed feature. The Cisco MDS documentation incorrectly reported this value.
Limitations and Restrictions
The following limitations and restrictions apply to all switches in the Cisco MDS 9000 Family.
The auto-sync Option
The auto-sync option is disabled by default. If you are replacing a faulty supervisor module, ensure that the auto-sync option is enabled so the software versions on both modules synchronize automatically. Once the supervisor synchronization is complete, verify that this option is disabled.
If one supervisor module is functioning and the other is not, boot the functioning supervisor module. Then use the booted supervisor module to bring up the supervisor module that is malfunctioning. Issue the reload module slot force-dnld command (after you log into the switch) where slot is the slot number of the malfunctioning supervisor module. If the auto-sync option is disabled, the supervisor modules will not synchronize automatically. In this case, enable the auto-sync option before issuing the reload module slot force-dnld command. Once the synchronization is complete, verify that this option is disabled.
See Chapter 5, "Software Images" in the Cisco MDS 9000 Family Configuration Guide.
This section lists the caveats and corrected caveats for this release. Use Table 3 to determine the status of a particular caveat. In the table, "R" indicates a resolved caveat, and "O" indicates an open caveat.
Table 3 Release Caveats and Caveats Corrected Reference
DDTS Number Software Release (Resolved or Open) 1.0(4) 1.0(5)
Symptom: Disabling or enabling the beacon mode on an interface may cause Fibre Channel modules to reboot.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea53477
Symptom: A Call Home process might restart after approximately 200-300 Call Home events are generated on the system. The configuration is retained.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea87033
Symptom: Some private loop device initiators (for example, SUN) are not properly registered with FLOGI. This results in the disks not being visible to the initiators.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea62969
Symptom: Fibre channel trace route functionality does not work correctly when issued from the Fabric manager, even though it works properly from CLI.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea55971
Symptom: Fabric Manager may report fewer devices in the fabric than those that are actually present.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea92168
Symptom: The counters for the Fibre Channel PortChannel are not shown correctly. The correct value should be sum of the counters for all member interfaces.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea51806
Symptom: If a new module is inserted after doing a hitless downgrade to 1.0(3) or 1.0(4) release, it does not come-up properly
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCeb13441
Symptom: On downgrading to 1.0(4) release, the modules which are supported in later releases, but not in 1.0(4) release, remain powered up. The correct behavior is for unsupported modules to be automatically powered down.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea89378
Symptom: Traceroute fails with a no route to host error from the Fabric Manager. The same destination succeeds from the CLI.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea46162
Symptom: During a nondisruptive upgrade if a name server query is pending, some Emulex HBA drivers do not respond to ELS commands issued on the switch, resulting in the link going offline and causing data traffic interruption.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea88972
Symptom: Under certain circumstances access to the switch may be denied and the switch may be unresponsive because of an error in the kernel tty driver.This may happen when you have multiple VSH sessions running simultaneously.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCea89199
Symptom: If automatic image synchronization is enabled, and the standby supervisor module is synchronizing the image from the active supervisor, the switch will not stop you from issuing the reload command on the active or standby supervisor modules. This may result in a failure to synchronize the images.
Workaround: Be sure to allow sufficient time for the images to be synchronized before reloading a supervisor module. Use the show system status redundancy CLI command to check the standby supervisor status.
Symptom: If you clear a kickstart boot variable that doesn't exist and if a kickstart boot variable with the same name size as the specified variable is stored in the system, the bootvar process crashes.
Workaround: Clear the kickstart boot variable using the no boot kickstart command.
Symptom: The management interface IP address changes to one of the IP Storage Services (IPS) module Gigabit Ethernet IP addresses after a system software downgrade.
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
Symptom: When the Fabric Manager or Device Manager communicates with the Cisco MDS switch through Virtual Private Network (VPN) or any Network Address Translation (NAT) scheme, a generic error message occurs while adding duplicate zone members from a VPN connection.
Workaround: None. If an error occurs while running through VPN/NAT, all errors will show up as generic errors without a detailed message describing the error.
Symptom: The Ethereal software application incorrectly decodes the A bit in the Common Service Parameters set as Normal, instead of Alternate BB_Credit Management.
Workaround: None. The trace must be interpreted correctly.
Symptom: During a system software upgrade or downgrade procedure, pressing Ctrl-C returns a message saying that the install procedure cannot be interrupted, while Ctrl-Z returns the prompt without any message. The install procedure continues in either case.
Symptom: The Fabric Manager or Device Manager reports an error for all operations if the switch is multihomed (both IPFC-based in-band management and the out-of-band management interface are up) and the Fabric or Device Manager was started using the IPFC address. Typically, you will see a notInTime window error in the Device Manager and all SNMP set operations fail.
Workaround: If the switch is multihomed, then start the Fabric or Device Manager on the switch using the out-of-band management interface IP address.
Symptom: The counter values freeze if the Device Manager port monitor window has been up and running for a long time (overnight or a few days).
Workaround: Close the frozen Device Manager window and re-open Device Manager.
Symptom: If the switch time zone is not UTC (default), the expire option for the username command returns an error. If the expire option is not specified, the username command functions properly.
Workaround: Temporarily change the time zone to UTC while creating a user-account.

Two types of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration. There is little or no impact to your business operations.
•Priority level 3 (P3)—Operational performance of the network is impaired, but most business operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.
•Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively impacted by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
•Priority level 1 (P1)—An existing 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.
