Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(6)
OL-27554-01
Caveats
Condition: This issue applies to the following NX-OS versions or platform combinations only:
– The Cisco MDS switches running MDS NX-OS Release 5.2(6), 5.2(6a), 5.2(6b), 5.2(8), 5.2(8a),
or 6.2(1).
– The Cisco Nexus 7000 switches running NX-OS version 6.1(3) or 6.1(4).
In addition, the following conditions must be true:
– Device-alias is set to enhanced mode by using the device-alias mode enhanced command.
– Multiple commands are performed on the same device-alias before a commit and one of which
is the rename command.
Note This issue occurs in both zone mode basic and zone mode enhanced.
Workaround: To avoided this issue group the device-alias commands of the same type together and
commit the changes before starting the next type. For example, use the device-alias commit
command after each and every same type of device-alias action. See the examples below.
Example 1
The following example shows how to delete the Alias2 and rename Alias1 to Alias2:
device-alias rename Alias1 temp_Alias1
device-alias rename Alias2 temp_Alias2
device-alias commit
Use the show device-alias session status command to verify the device-alias session status.
device-alias rename temp_Alias1 Alias2
device-alias commit
Use the show device-alias session status command to verify the device-alias session status.
If you do not need temp_Alias2, use following commands:
device-alias delete temp_Alias2
device-alias commit
The following example shows how to delete the Alias2 and rename Alias1 to Alias2:
Example 2
device-alias delete Alias2
device-alias commit
Use the show device-alias session status command to verify the device-alias session status.
device-alias rename Alias1 Alias2
device-alias commit
Use the show device-alias session status command to verify the device-alias session status.
Note You can use multiple device-alias commands of the same type such as delete, rename, and add in the
same batch if the names of all the device-alias that areaffected are unique.
