Symantec NetBackup, Manual, Page: 26 / 168

■
The destination disk pool does not include a storage server with a restore
or a duplication attribute.
■
A preferred or required storage server cannot be used because it is
unavailable (NetBackup considers it DOWN).
■
A restore or a duplication operation is queued.
The reason may be that a preferred or required storage server cannot be used
because it is unavailable (NetBackup considers it DOWN).
If you do not configure preferred or required restore servers, NetBackup uses
normal criteria to select a media server for restore or duplication. (That is, if you
configure more than one storage server.)
Information about how NetBackup balances storage unit and media server load
is available.
See “Maximum concurrent jobs” in the following guides:

You can use preferred or required restore servers rather than the Media host
override host property.
Information about the Media host override property is available.

To enable preferred or required servers for restore or duplication, do the following:
■
Upgrade the NetBackup master server and the NetBackup EMM server to
NetBackup 6.5.2 or later. (Normally, the master server and the EMM server
are on the same computer.)
■
Optionally, to enable command-line support on media servers, upgrade the
media servers that are used for AdvancedDisk operations to NetBackup 6.5.2
or later.
You do not have to upgrade the media servers. You can configure and manage
the restore and the duplication storage servers by invoking the commands on
the master server.
Configuring an AdvancedDisk storage server
Configure in this context means to configure as a storage server a NetBackup
media server that can mount the storage.
