Volume Pools and Volume Groups
284 NetBackup Media Manager System Administrator’s Guide for Windows
◆
If the scratch pool contains assigned volumes, these volumes remain in the scratch
pool. Media Manager does not move assigned volumes to other pools as it does with
unassigned volumes.
◆
Media Manager will not assign volumes while they are in a scratch pool. For example
if a NetBackup policy or schedule specifies the scratch pool, all requests for those
volumes are denied.
◆
Media Manager returns expired media to the scratch volume pool automatically
(media that is returned must have been originally in the same scratch pool).
If this logical move is not desired, you can specify an entry in
vm.conf
to disable this
behavior (see “Return Media to the Scratch Pool” on page 333). If this entry is used,
the move must be done using Media and Device Management from the NetBackup
Administration Console.
◆
To have Media Manager manage the allocation of your volumes to your volume
pools, do the following:
a.
Create volume pools as required, but do not add any volumes to the pools.
b. Define a scratch pool and add all of your volumes to it. Media Manager will move
volumes to the other pools as they are needed.
Moving Volumes
Common instances when you move volumes are as follows:
◆
Replacing full volumes in a robotic library. When a volume is full and there are no
more empty slots in the robotic library, you move the full volume to standalone and
configure a volume for the empty slot, or move a volume into that slot. Use the same
process to replace a defective volume.
◆
Moving volumes from a robotic library to an offsite location or from an offsite location
into a robotic library. When you move tapes to an offsite location, you move them to
standalone.
◆
Moving volumes from one robotic library to another (for example, if a robotic library
is down).
◆
Changing the volume group for a volume or volumes.
Move Operations
In one move operation, you can move a single volume, multiple volumes, or combinations
of single and multiple volumes. You are limited only in that you cannot move volumes to
an invalid location (for example, DLT media to an 8 mm robot).
