[SamPaul]

Trying to delete a disk pool in our environment but its not getting deleted.
Its throwing the following error,

DSM has found that one or more volumes in the disk pool mps2647_dp_fs_avid(DataD
omain)@mps2647 has image fragments
failed to delete disk pool, invalid command parameter

>  Tried expiring the images using bpexpdate, but its showing as 'no entity found'.
>  Tried deleting using 'nbdelete' and 'nbstlutil -cancel -backupid' and again tried deleting but still could not delete the disk pools.

>  The disk volume is configured in DataDomain and have deleted the disk volume in DD. Still could'nt delete from Netbackup.

Please share ur views to get a solution

Find the disk pools Disk Media ID 

For example (I'm making the assumption it's a storage type of DataDomain here)

nbdevquery -listdv -stype DataDomain-dp mps2647_dp_fs_avid -U

then try:

nbdelete -purge_deletion_list -media_id @<disk media id>

[SamPaul]

Obtained the media id and tried deleting using nbdelete,

D:\Veritas\NetBackup\bin\admincmd>nbdelete -dt 0 -media_id @aaaba -media_server
mps2647

But this is also not working

Which version of NetBackup are you running?

For 7.1 try: nbstlutil remove_all -mediaid @aaaba –force

For 7.5 try: nbstlutil remove_exp -force

If it still wont go then it may have images stuck in EMM - if that is the case you will need to log a call with Support who can do you an EEB that runs a SQL script to remove the entries from the database

Mark,

It was indeed helpful.  When i gave "nbstlutil remove_all" for the specific Disk Media id, the command prompt got hung. I cancelled that  and verified the Disk pools in GUI console, it was showing all Disk pools got deleted. But after some time, all DP's were visible. Then i tried deleting the DP which has to be deleted and it happened.

Thanks

But am not sure, why initially it was showing as All Disk pools got deleted? Also the GUI console got hung completely for a couple of minutes.
