Resolved Caveats

CSCeb83751

Symptom: A Cisco MDS 9500 director, with 16-port modules currently running version 1.1(2), 1.1(3), or 1.2(1A), that was non-disruptively upgraded from version 1.0(x), 1.1(1), or 1.1(1A) and then encountered a link reinitialization on one of the 16 ports can cause the system to get into an unpredictable state and may require a switch reset to recover.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCeb83751

CSCec09428

Symptom: If hosts registered as SNMP target table are deleted repeatedly, while the switch is busy sending notifications to them, the SNMPD process may restart (indicated in syslog message).

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCec09428

CSCec12608

Symptom: On issuing the show port internal info command, the port process may fail. This command is also executed as part of the show tech-support details command. There is no effect on the software when the port process restarts.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCec12608

CSCec09545

Symptom: A Compaq RAID with HSG-based controller connecting to a Cisco MDS switch fails to establish connection to a remote Compaq RAID with HSG-based controller due to an invalid response from the Name Server.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCec09545

CSCec16242

Symptom: When you issue a show fcdom fcid persistent command, the domain manager software sometimes causes vsh to dump the core.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCec16242

CSCec24378

Symptom: The show version command output may create a core file when a image is downgraded. This does not impact system behavior.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCec24378

CSCeb19609

Symptom: After plugging and unplugging a Gigabit Ethernet cable multiple times the PortChannel gets isolated and issues a remote domain manager not responding error.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCeb19609

CSCec10006

Symptom: When a VSAN is used as a SPAN source, and the VSAN includes an FCIP interface, SPAN fails.

Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCec10006

Open Caveats

CSCdz31332

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.

CSCeb01264

Symptom: When you issue the copy startup-config running-config command on a switch which is already up and running, the trunking ports may flap, due to reapplication of allowed VSANs for trunking ports in the startup configuration.

Workaround: Ensure that the startup configuration does not contain any allowed VSAN configuration for trunking ports (trunking ports default to the allowed VSAN configuration).

CSCeb05095

Symptom: If a copy running-config startup-config command is issued when a switching module is temporarily down, the configuration for that module will be deleted from the system. This primarily occurs at boot time before all the modules are online.

Workaround: First issue the show module command to ensure that all modules are online before issuing a copy running-config startup-config command.

CSCeb16270

Symptom: Avoid using the same TCP port number for iSCSI and FCIP protocols on an IP Storage Services module (IPS module) port.

Workaround: None.

CSCec30443

Symptom: The iSCSI host cannot open an iSCSI session to the IPS module when the TCP selective acknowledgement (SACK) option is enabled.

Workaround: Disable TCP SACK on the iSCSI interface.

CSCee06496

Symptom: If you are running Cisco MDS SAN-OS releases 1.1(3), 1.2(1a), 1.2(1b), 1.2(2a), 1.3(1), 1.3(2a), 1.3(3), or 1.3(3c), the following sequence of operations might lead to the failure of one or both supervisor modules simultaneously:

a. Removing an IPS-8 module from the switch.

b. Inserting a different type of module in the same slot.

c. Configuring the new module.

d. Issuing the copy running-config startup-config command.

Removing the IPS-8 module at any time and replacing with another IPS-8 module does not cause this problem.

Workaround: Before replacing an IPS-8 module with a different type of module in the same slot, upgrade to Cisco MDS SAN-OS Release 1.3(4a).

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.

CSCeb01112

Symptom: Importing the ASCII configuration multiple times in the same switch can cause the FCIP interface to go into error disabled state.

Workaround: None.

CSCdz12179

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.

CSCdz43707

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.

CSCea60652

Symptom: For iSCSI configurations, both no pwwn hh:hh:hh:hh:hh:hh:hh:hh and no pwwn auto number delete all the pWWNs for a given target.

Workaround: None.

CSCeb18066

Symptom: If you change the iSCSI switchport identification from name to IP address, the TCP sessions are not terminated.

Workaround: None.

CSCea80896

Symptom: The Fabric Manager and Device Manager do not support iSCSI TCP parameter configuration and display.

Workaround: None.

CSCeb10797

Symptom: When you delete a pWWN for an auto-created iSCSI initiator using the Device Manager, (removed from snmp fcAddress table), it still shows up in the CLI (the initiator is still auto-created).

Workaround: None.

CSCdz43106

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.

CSCea45726

Symptom: The Device Manager shows a port in the down state (red square) when the operational status of the port is up. This rare occurrence is due to the failure cause of the port not being empty (for example, the failure case reflects the initializing state).

Workaround: None.

CSCea82028

Symptom: When a switch is upgraded while the Device Manager for that switch is open, a Java error of class cast exception occurs. When this error occurs, some Device Manager menu items are unusable while other menu items remain in this error state.

Workaround: Close the Device Manager and reopen it.

CSCeb19588

Symptom: Sometimes, the zone merge import command results in isolation.

Workaround: Reissue the command to resolve the isolation problem.

CSCeb34865

Symptom: The following error message is issued when you try configuring switch drop latency:

changing this parameter is not allowed could not update the value

Workaround: None. Switch drop latency is not configurable in this release of the software.

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.
