by clicking the Detail button on the Active Library Controller
or Failover Library Controller panes.)
- In a library configured in the SAN environment, where several
MediaAgents are configured as library controllers, at any given
point, the MediaAgent accessing the library is considered as Active
and therefore displayed as the Active Library
Controller. All the other MediaAgents are displayed as Failover
Library Controllers. The Active status will be displayed as No
for the failover library controllers.
- In a library configured in the non-SAN environment, where only one
MediaAgent is configured as a library controller, the MediaAgent is
displayed as the Active Library Controller. If either the Alive or
Enabled status is NO, or Soft State is OFF, the Active status will be
displayed as OFF and the MediaAgent will be displayed as
a Failover Library Controller.

Deconfigure Drives
Before you Begin
The number of configured drives in a drive pool cannot be smaller than the
largest number of streams used by any storage policy that accesses that drive
pool. For example, assume that a drive pool containing four drives is accessed
only by a three-stream storage policy. In this case, you can deconfigure only one drive within the drive pool.
The system prevents you from deconfiguring
any additional drives. To deconfigure additional drives, you must first reduce
the number of streams in the storage policy.
|
Some Agents/database applications have the following requirement: The number
of streams through which the database is restored must equal the number
of streams through which the data was backed up. If you have used a
storage policy for multi-stream database backups we advise you not to
reduce the number of streams. |
To
deconfigure a drive:
- Be certain that the drive that you want to deconfigure is not in use. Use the Job
Controller to find and kill any jobs that use the drive. (For information on the
killing a job from the Job
Controller see
Killing a Job.)
- Make sure that a media is not mounted in the drive.
-
Display
the Library and Drive Configuration window.
- Right-click the drive that you want to deconfigure, and then click Deconfigure.
- Click Yes in the confirmation prompt that appears to deconfigure the
drive.
The status of the drive changes to not configured.
