Caveats
Symptom: Some Fibre Channel Routing (FCR) peers might get out of sync with the master switch
FCR peer after an Inter-Switch Link (ISL) flap. This might cause the intelligent application flows
not to come online or to get deleted.
Workaround: This issue might occur when using any of the following FCR intelligent applications:
Storage Media Encryption (SME)
I/O Acceleration (IOA)
Data Mobility Manager (DMM)
Workaround: Check the intelligent applications to verify whether any flows are deleted on the
problematic switch. If they did, you must recreate flows again through the application CLI or the
Cisco Fabric Manager or Cisco Data Center Network Manager (DCNM)-SAN interface.
Enter the following supervisor CLI commands on the problematic FCR switch that triggers it to
resync its configuration with the rest of the fabric.
For a single switch, use the following command:
test fc-redirect config sync-with-fabric
If more than one peer is affected by this issue, use the following command:
test fc-redirect config sync-with-fabric all-peers

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: After creating an SME cluster, adding disks to a disk group, changing some disk states,
and starting the master key rekey, the key creation date is invalid.
Workaround: None.
