Removing MSDP / storage units

Hi all,

I manage an environment with one master controlling 13 media servers that were all configured with attached external drives (SAN) that were configured for MSDP. Each site also has a local tape drive.

The SAN at each site is now being used for our AD project and I will now point all backups directly to tape. I was wondering the proper way to delete these MSDP pools in my environment - just delete the storage unit associated with the SAN?

Does anything need to happen to the storage server at each site?

Thanks!

    Hello,

    The process is pretty straight foward. From HOWTO88972, Deleting a Media Server Deduplication Pool:

    You can delete a disk pool if it does not contain valid NetBackup backup images or image fragments. If it does, you must first expire and delete those images or fragments. If expired image fragments remain on disk, you must remove those also.

    See Cannot delete an MSDP disk pool.

    If you delete a disk pool, NetBackup removes it from your configuration.

    If a disk pool is the storage destination of a storage unit, you must first delete the storage unit.

    To delete an MSDP disk pool

    1. In the NetBackup Administration Console, expand Media and Device Management > Devices > Disk Pools.
    2. Select a disk pool
    3. On the Edit menu, select Delete.
    4. In the Delete Disk Pool dialog box, verify that the disk pool is the one you want to delete and then click OK.

    I think the primary concern would be the images that currently reside in those disk pools. Once you have stopped writing new images, duplicated all existing images and expired the copies in the pool then there is nothing left for the pool to do. You should certainly remove it from your Netbackup environment if you want to avoid sending data there. 

    As for the disk, it's a disk. Contact the storage admin and have him format it for the new project. I imagine you would format it NTFS and change the LUNs to present the disks to different servers. You want to remove the mappings to the media servers because you don't want them to show up as local disk to the media servers anymore. Reboot the media servers after LUN is removed and they will be out of sight, out of mind.
