Volume Pools and Volume Groups
280 NetBackup Media Manager System Administrator’s Guide for Windows
Volume Pools and Volume Groups
A volume pool is used to identify a logical set of volumes by usage.
A volume group is a logical grouping that identifies a set of volumes that reside at the
same physical location. Volume groups are convenient for updating a configuration when
moving volumes (for example, from robotic to standalone).
Volume pools and volume groups are specified when you add the volume to the Media
Manager configuration.
Volume Pools
The volume pool concept is relevant only for NetBackup storage units managed by Media
Manager and does not apply to disk storage units.
Associating volumes with a volume pool protects them from access by unauthorized
applications. You can create volume pools for applications or other reasons, and as you
add volumes, associate them with the appropriate pool. You can also move unassigned
volumes to a different pool later.
With the exception of the NetBackup and DataStore special volume pools, you must create
a volume pool before you can add volumes to it. By default, Media Manager creates
volume pools, named NetBackup and DataStore.
During initial configuration, it is easiest to create all of your volume pools first if you want
to use volume pools other than the NetBackup volume pool. Then as you add volumes,
you can assign them to these volume pools.
You can also configure a scratch volume pool (see “Scratch Volume Pools” on page 282).
Volume Groups
Volume groups are an administration tool for logically moving multiple volumes (where a
logical move means to change the volume attributes to show the new location).
Using a volume group lets you move a set of volumes between a robotic library and a
standalone location, or delete them from the configuration by specifying the group name,
rather than each individual media ID of each volume. Volume groups are also convenient
for tracking the location of volumes, such as the case when a group is moved off site.
Rules for Assigning Volume Groups
The following are the rules for assigning volume groups:
◆
All volumes in a group must be the same media type.
