Hello Robert, 
the behavior of the TSM server was changed as we received PMRs from users 
not being able to access their VM backups after such renames. 
Thus with APAR IC92869 (
https://www-304.ibm.com/support/entdocview.wss?uid=swg1IC92869) the 
ability to rename file spaces of VM backups was disabled. 

What is the reason, why you rename the file space? Is the original VM 
disposed and you want to mark this deletion in the file space name by 
renaming it? 
So do you want to keep the file space as inactive until you finally delete 
it? 
In that case you may use the "FORCE=YES" option together with the rename 
file space command. This will bring back the old behavior of the command. 

However 
- once a file space is renamed it will no longer show up when you look for 
existing backups in the VE GUI
- If you want to rename the file space because the VM was renamed, you 
will not be able to access any old backup under the new name. You will 
have a mixture of accessible and inaccessible backups within one file 
space. 
- Once renamed you have to rename the file space back to the original 
name, if you want to access VM backups. 

I hope that helps. 

Mit freundlichen Grüßen / best regards

Hello

Tried to rename a filespace of a VM machine backuped with TSM for VE 7.1.1 
on a TSM server version 7.1.1

The datacenter node name is:  HAIFA_DATACENTER

Doing  a query as:  q fi   HAIFA_DATACENTER   (here the output)

Node Name                    Filespace Name           FSID        Platform 
            Filespace Type       Is Filespace Unicode       Capacity Pct

HAIFA_DATACENTER     \VMFULL-mdb2        106          TDP VMware API:TSMVM 
             No                                        0 KB 0.0


Did the command:     ren fi   HAIFA_DATACENTER   \VMFULL-mdb2 
\VMFULL-mdb2_OLD

But got this error !

ANR1998E RENAME FILESPACE: Invalid value for current_file_space_name 
parameter - \VMFULL-mdb2.

I did it so many times but this is the first time for a VM machine !

Any help   !!!!

Regards Robert
