Hello,
Per the Kb you mentioned, you should be able to run the command listed at the cluster level.
You will need to rename the volume to a different name then rename it to the original name in able to get rid of the (1) appended to it.
For example:
Original volume name is test.
After moving it it is called "test" at the cluster level but "test(1)" at the node level.
Cluster::> vol rename -vserver <vserver name> -vol test -newname test2
Cluster::> vol rename -vserver <vserver name> -vol test2 -newname test
Once complete you can verify by running the below command:
Cluster::> vol show -vserver <vservername>
CLuster::> system node run -node <nodename> -command "vol status"
Thanks
