How do delete a MSDP disk pool, after I removed the storage server first ?

[AndersA]

Hi all,

I accidentally deleted my storage server before i deleted the MSDP disk pool, now i cant delete the disk pool because it needs a storage server.....any ideas ?

master:

Netbackup 7.5.0.4 on Redhat 5.7

media (MSDP):

Netbackup 7.5.0.4 on Redhat 6.3

you can not delete the Storage server if it has associated disk pool.

frist you have the remove the diskpool then only you can remove the storage server.

so please make sure that the disk pool is associated with any other storage server..

note:-removing disk pool will expire all the images  in it.

please see below.

If a disk pool is configured from the disk volume that the deduplication storage server manages, you cannot delete the deduplication storage server.

Have you already tried to readd storage server?
I'm not sure this works, but worth to try.

Hi,

the same problem happened with me and i solve it.

follow the steps from this link, but first run this command (nbemmcmd -listhosts) to check the server storage still available or not.

Good Luck.

too late i am afraid...the pool on the actual MSDP and all the data....is gone.

In order to delete the storage group. We need to expire all iamges, delete storage units and then disk pool. After all this Netbackup allows to delete storage server.
Please provide me more information how you have deleted storage server directly?

Hi Nagalla

You are incorrect, it is possible to delete the storage server before you delete the pool....but you are correct, it shouldent be :).

if you have a test setup try this, and you can see it for yourself.

expire all images in pool gui or cli
remove stu from gui
nbdelete -allvolumes -force

nbdevconfig -changestate -stype PureDisk -dp POOL -state DOWN
nbdevconfig -changedp -dp POOL -stype PureDisk -del_storage_servers msdp-server.org
nbdevconfig -deletests -storage_server msdp-server.org -stype PureDisk
nbdevconfig -deletedp -dp pdde0b-1 -stype PureDisk  //ERROR storage server gone!!

right order would be:

nbdevconfig -changestate -stype PureDisk -dp POOL -state DOWN
nbdevconfig -changedp -dp POOL -stype PureDisk -del_storage_servers msdp-server.org

nbdevconfig -deletedp -dp pdde0b-1 -stype PureDisk

nbdevconfig -deletests -storage_server msdp-server.org -stype PureDisk

Hi Ruchi,

I am well aware how it should be done, i just messed it up.

this way it is possible to delete the storage server before deleting the pool (properly a bug)

if you have a test setup try this, and you can see it for yourself.

expire all images in pool gui or cli
remove stu from gui
nbdelete -allvolumes -force

nbdevconfig -changestate -stype PureDisk -dp POOL -state DOWN
nbdevconfig -changedp -dp POOL -stype PureDisk -del_storage_servers msdp-server.org
nbdevconfig -deletests -storage_server msdp-server.org -stype PureDisk
nbdevconfig -deletedp -dp pdde0b-1 -stype PureDisk  //ERROR storage server gone!!

right order would be:

nbdevconfig -changestate -stype PureDisk -dp POOL -state DOWN
nbdevconfig -changedp -dp POOL -stype PureDisk -del_storage_servers msdp-server.org

nbdevconfig -deletedp -dp pdde0b-1 -stype PureDisk

nbdevconfig -deletests -storage_server msdp-server.org -stype PureDisk

Hi Muhanad

I have followed this doc, but still i cant delete the old diskpool... says i need a storage server. ...bummer.....maby its a support call.

[RamNagalla]

below is the command that gets you all mess ups, you does not needs to run it.

nbdevconfig -changedp -dp POOL -stype PureDisk -del_storage_servers msdp-server.org

[AndersA]

yeah you are right... but my problem is the i have.....and then i could remove the storage server before the pool...which i did....now my problem is how do i get rid of the pool.?

[RamNagalla]

try if you can associate the pool with another storage server that is avaliable, by using nbdevconfig -changedp( I am not sure if it helps , i never tired, but its worth to try..)

if this does not help, I am seeing only support call is left.

[AndersA]

tried

nbdevconfig -changedp -stype PureDisk -dp POOL -add_storage_servers MSDP.server.net -M master.server.net

DSM has found that PureDiskVolume already exists in the database
Unable to add host MSDP.server.net
failed to change disk pool, operation would cause an illegal duplication

bummer :/.

better call support :).

[Mark_Solutions]

What is the output of:

nbdevquery -listdv -stype PureDisk

Have youi deleted all SLPs and storage units that relate to that pool?

Have you tried to just delete it from the Admin Console?

Thanks

[AndersA]

Still waiting for support. :)

[Marianne]

Does this mean that you have a Symantec Support call open?

Or waiting for support from forum members?

Symantec Support call is probably best option - they will be able to provide sql scripts to remove orphaned EMM entries.

[AndersA]

We have  3party local support, and i am waiting on them to make the symantec support call.

finally got a script from sym. support that cleaned out the database.
