Workaround
: Use CFS regions if a large number (greater than 512) of application flows need to be
configured. CFS regions segment the FCR peer topology into manageable proportions.

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.

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.

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.
