Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(8b)
OL-27554-06
Caveats
• CSCug67068
Symptom: On Cisco MDS 9148 and MDS 9134 switches, an attempt to overwrite a file fails with
the following error:
Permission denied
Condition: This issue occurs if a previous attempt to copy to a file with the same name failed.
Workaround: None.
• CSCuh37423
Symptom: After changing the device alias configuration, the I/O Accelerator (IOA) flows remain
unchanged until the reactivation of the zone set.
Condition: This situation occurs during a device-alias add, delete, or rename operation.
Workaround: None.
• CSCuh49283
Symptom: A zone member goes offline; a Registered State Change Notification (RSCN) is not sent
to zone members; the device-mapping entry, port world wide name (pWWN) associated to a device
alias is not displayed in the Dynamic Port VSAN Membership (DPVM) database; the show
running-configuration ivr command does not display the changes when a device alias member in
an Inter-VSAN routing zone (IVR zone) is renamed; the port world wide name (pWWN) associated
with the device alias is found dissociated in the port security database; a device alias member is not
found in the port security database.
Condition: This situation occurs when all or one of the conditions is met:
– A user attempts to perform a device-alias operation in batch, such as renaming an offline device
alias to an existing online device alias or vice versa.
– A device alias was renamed.
– A device alias was deleted and an existing device alias is renamed to the deleted device alias in
the same commit.
– A device alias, which is not configured, resides in the DPVM database and an online device is
renamed to the former.
– The IVR distribute option is enabled and the device alias is in enhanced mode, and the changes
in a device alias is not updated to the IVR running configuration.
Workaround: Add the offline member to the device alias database, revert to the previous name if
you have renamed a device alias, and flap the ports that are connected to the affected zone member.
• CSCuh57761
Symptom: Multiple port security members that are mapped to a switch WWN (sWWN) logging
point are not fully distributed to the peer switches. The following error appears after an Cisco
In-Service Software Downgrade (ISSD), followed by entering the port-security commit command:
Internal CLI error: Timer expired
Condition: This situation occurs after an ISSD from Cisco MDS NX-OS Release 5.2(8b) to 5.2.(1).
After creating and committing port-security entries that map multiple port security members to the
same sWWN, all entries are not distributed to the peer switches.
Workaround: None.
