CFS regions segment the FCR peer topology into manageable proportions. • CSCtr29423 Symptom: Tape acceleration is not working with the Emulex CNA card. This issue can be seen because the Emulex CNA card uses the same OXID for all fast-path SCSI commands (read/write), which breaks tape acceleration logic for accelerating the read/write IOs. Workaround: None. • CSCtr50223 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. • CSCtr55608 Symptom: Following the insertion of the 32-port 8-Gbps Advanced Fibre Channel switching module (DSX9232-256K9), the following syslog message is displayed: 2011 Jul 16 05:35:00 emc-9513-II %SYSMGR-STANDBY-3-UNACCEPTABLE_WAIT: Service "r es_mgr", no response from System Manager after 10 seconds. Terminating. This issue might be seen if you enter the no install feature-set fcoe command, then power down the 32-port 8-Gbps Advanced Fibre Channel switching module, and then insert the module again, which triggers the install feature-set fcoe command. Workaround: None. This is a not an operationally impacting issue because it happens on the standby supervisor, and the standby supervisor can successfully come up in spite of the syslog message.
