OpenStorage storage unit properties
Description Property
Provide a unique name for the new storage unit. The name can describe the type of storage.
The storage unit name is the name used to specify a storage unit for policies and schedules.
The storage unit name cannot be changed after creation. Storage unit name
Select Disk as the storage unit type. Storage unit type
Select OpenStorage (VendorName) for the disk type. VendorName is a string provided by the
storage vendor that identifies the vendor or storage. Disk type
Select the disk pool that contains the storage for this storage unit.
All disk pools of the specified Disk type appear in the Disk pool list. If no disk pools are
configured, no disk pools appear in the list.
Disk pool
Specify the NetBackup media servers that can move data to the storage server for this storage
unit. (For OpenStorage, NetBackup media servers function as data movers.)
Only the media servers that are configured as data movers for the OpenStorage implementation
appear in the media server list. If a media server does not appear in the list, verify that the
software plug-in is installed and that logon credentials are created.
Specify the media server or servers as follows:
■
To allow any media server in the media server list to move data to the storage server, check
Use Any Available Media Server.
If you configure more media server data movers in the future, you do not have to update
the storage unit. After you install the plug-in and configure the credentials, NetBackup
automatically uses the media servers for the backups that are sent to the storage unit.
■
To restrict the media servers that can move data to the storage server, check Only Use The
Following Media Servers. Then select the media servers that are allowed to move the data.
Any media server in the list can receive data from the storage server; it does not have to be
selected. A media server receives data for restore jobs and for storage monitoring purposes.
NetBackup selects the media server to use when the policy runs.
Media server
Specify the largest fragment size that NetBackup can create to store backups.
The default maximum fragment size for a disk storage unit is 524,288 megabytes. To specify
a maximum fragment size other than the default, enter a value from 20 megabytes to 524,288
megabytes.
Backups to disk are usually fragmented to ensure that the backup does not exceed the maximum
size that the file system allows.
If an error occurs in a backup, the entire backup is discarded. The backup restarts from the
beginning, not from the fragment where the error occurred. (An exception is for backups for
which checkpoint and restart are enabled. In that case, fragments before and up to the last
checkpoint are retained; the fragments after the last checkpoint are discarded.)
