Symptoms

Renaming a Thin Clone created on a normal LUN works fine from the Unisphere GUI.  However, the same rename operation for a Datastore LUN does not complete and the GUI gets hung on Applying Changes.
No jobs get created and the GUI never completes the change.

Cause

Functionality issue 

Resolution

FIX:
Issue is fixed in Unity OE 5.2.0.0.5.173

Workaround:

Use CLI in service mode to rename the datastore thin clones with below command:

uemcli -u admin -p <password> /stor/prov/vmware/vmfs -name <current_name> set -name <new_name>

Note:  If you are unable to execute the command as service, please contact Dell Technical Support or your service provider and refer to this KB.

service@CKXXXXXXXXX spa:/cores/service/user# uemcli -u admin -p <password> /stor/prov/vmware/vmfs show
