DBBackup Volumes

[Al'shaebani, Bassam]

I'm in the intial steps of implementing DRM, I noticed that with only my
database volumes are being moved from mountable to vault, once they are
shipped out, they never get reclaimed or moved from vault to pending.
Last message in the actlog for those volumes is 'volume moved from
mountable to vault' . My drm pool volumes do get reclaimed. 
Did anyone come across an issue similar to this one?
Thanks
