VNX: After renaming the CIFS server on VDM, localuser is not enabled. (User Correctable)

Local user was originally enabled on the CIFS server, but after rename of the CIFS Server, local user is not enabled.

Result of server_cifs <vdm_name> command in case of no problem:
>> CIFS Server <new-cifs-name>[<domain_name>] RC=x (local users supported)

Result of server_cifs <vdm_name> command in case of problem:
>> CIFS Server <new-cifs-name>[<domain_name>] RC=x 

[note]
As a precondition, when rename a CIFS Server, the correct procedure must be followed.
If the correct procedure is followed and an event occurs, it may match this knowledge base.

Please refer to "Rename a compname" on Page 74.

example:

server_cifs <vdm_name> -Unjoin compname=<old-cifs-name>,domain=<domain_name>,admin=<admin_name>
server_cifs <vdm_name> -delete compname=<old-cifs-name>

server_cifs <vdm_name> -add netbios=<old-cifs-name>,domain=<domain_name>,interface=<interface_name>
server_cifs <vdm_name> -rename -netbios <old-cifs-name> <new-cifs-name>
server_cifs <vdm_name> -delete netbios=<new-cifs-name>

server_cifs <vdm_name> -add compname=<new-cifs-name>,domain=<domain_name>,interface=<interface_name>
server_cifs <vdm_name> -Join compname=<new-cifs-name>,domain==<domain_name>,admin=<admin_name>

This is a timing issue where localgroup file was not updated before domain join.
As a best effort, adding around 90 seconds delay before domain join is expected to reduce the occurrence of the event.

This problem is expected to be corrected by performing the VDM reload operation with the following command.

nas_server -vdm <vdm_name> -setstate mounted
nas_server -vdm <vdm_name> -setstate loaded

[Note]
When VDM is mounted or unloaded, services on the corresponding VDM are temporarily unavailable.

- This is an example of the time from the start to the end of a command.

- If the event matches, the following error is generated at the time of attempting a JOIN of the renamed CIFS Sever.
