Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(1)
OL-25090-01
Caveats
for that device. If you configure the same device in DPVM using NWWN and enter the
activate
force
command, the device is not logged out and does not login again to the NWWN configured
VSAN.
Workaround
: To work around this issue, do one of the following:
1.
Create a DPVM configuration by PWWN instead of NWWN.
2.
Create an alias configuration for PWWN, delete the DPVM device alias configuration, and then
delete the alias configuration.
3.
Enter the
shut
command followed by the
no shut
command on the interface.

Symptom
: On a Cisco MDS 9000 switch, the tech support CLI for some FCoE components, like
VLAN_MGR and ASSOC_MGR, may appear as part of the
show tech-support
command output,
even though the FCoE plugin is not loaded.
Workaround
: None.

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
: When you have IVR zone member with devices attached to the 8-port FCoE module
(DS-X9708-K9) or the 48-port 8-Gbps Advanced Fibre Channel switching module
(DSX9248-256K9) and you perform certain actions like module reload, VSAN suspend, device port
flapping, the device does not get exported and the FC ID rewrite entries are missing. This issue
might be seen when there are IVR zone member with devices attached to the 8-port FCoE module
or the 48-port 8-Gbps Advanced Fibre Channel switching module and you do any of the following:
–
Flap the device port on the 8-port FCoE module or the 48-port 8-Gbps Advanced Fibre Channel
switching
–
Reload the module with the device attached
–
Suspend or no suspend the VSAN where the device is a member
Workaround
: Enter the
ivr refresh
command to help re-advertise this device and get the rewrite
entries programmed.

Symptom
: Configuring a static area FC ID with an area that was used for a single static FC ID
configuration will fail. This issue impacts only the area where a single static entry is added and
removed later, particularly if the area will still available for a single FC ID configuration.
Workaround
: Instead of entering the
no vsan
command to remove the single static FC ID, convert
the existing static single FC ID to a dynamic one, and then purge to clear the area. The area will still
be available for a static area FC ID configuration.

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
