Caveats Condition: When a user tries to run the tape traffic with TIE through IOA the port software fails. Workaround: This issue is resolved. • CSCud41024 Symptom: A module gets reloaded because of a virtual service domain (VSD) process crash. Condition: The VSD core file is recorded in the output of the show core command. Workaround: This issue is resolved.
Caveats Condition: If the user modifies an active FCIP tunnel compression parameter from the Device Manager, unwanted logs get redirected to the startupdebug file of the MSM-18/4 module. Because of the high utilization of the FCIP tunnel, this operation creates a large (4 MB) file that causes memory exhaustion. Workaround: This issue is resolved. • CSCue92054 Symptom: The inter-VSAN routing (IVR) feature checks out the SAN_EXTN_OVER_IP_18_4 license that results in the FCIP shut down.
Caveats Workaround: This issue is resolved. • CSCue51710 Symptom: The Inter-VSAN Routing (IVR) processes crash with the following error: SYSMGR-2-SERVICE_CRASHED Service Workaround: This issue is resolved. • CSCue53811 Symptom: The I/O Accelerator (IOA) flows are stuck in VT_CREATE because of the error in the Resource Manager (RM). Workaround: This issue is resolved.
Caveats 2013 May 9 12:29:20 sw-DC2-9509-sw8 %SYSMGR-2-SERVICE_CRASHED: Service "ivr" (PID 32689) hasn't caught signal 11 (core will be saved). Workaround: This issue is resolved. • CSCuf93813 Symptom: The Fibre Channel Name Server (FCNS) database does not get synchronized. Condition: When there is a large switch fabric with more than 8000 entries in the FCNS database. Workaround: This issue is resolved.
Caveats Symptom: User cannot reset the timeout value by using the tune lrtp-retx-timeout command after an IOA failure. Condition: This occurs if the tune lrtp-retx-timeout command is used set to a nondefault value and there is an IOA port software failure. The default timeout value is 2500 milliseconds. Any configured value that is different from the default is not reinitialized properly after a failure. Workaround: This issue is resolved.
Caveats Symptom: An interface on the Cisco MDS switch flaps for 9 to 10 seconds with the following error: 2013 Feb 3 02:26:45 EST: PORT-5-IF_DOWN_NONE %$VSAN 202%$ Interface fc1/2 is down (None) 2013 Feb 3 02:26:55 EST: PORT-5-IF_UP %$VSAN 202%$ Interface fc1/2 is up in mode F Condition: This situation occurs during a normal operation. Workaround: This issue is resolved.
Caveats • CSCug49301 Symptom: Virtual Shell (VSH) crashes while collecting the Fibre Channel over IP (FCIP) technical support information and displays the following error message: %VSHD-2-VSHD_SYSLOG_EOL_ERR: EOL function fcip_show_ta_info_all from library libips_mgr_fcip.so exited due to Signal 11 Workaround: This issue is resolved.
Caveats Condition: After an In Service Software Upgrade (ISSU) the configuration is saved and a switchover is performed. Workaround: This issue is resolved.

Caveats 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.
Caveats Condition: When a virtual machine (VM) moves to another partition, the VIO performs a LOGO first and then with the same World Wide Name (WWN) from the new location does a fabric login (FLOGI) or FDISC again. This occurs within 10 milliseconds to minimize downtime to the VM. Workaround: None. • CSCuf82609 Symptom: After an In Service Software Upgrade (ISSU) on the Cisco MDS 9222i switch, Cisco Fabric Services (CFS) merge is initiated. Workaround: None.
