Managing deduplication disk pools

To determine disk pool state

1In the NetBackup Administration Console, expand Media and Device Management > Device Monitor.

2Select the Disk Pools tab.

3The state is displayed in the Status column.

Determining the deduplication disk volume state

Use the NetBackup nbdevquery command to determine the state of the volume in a deduplication disk pool. The command shows the properties and attributes of the PureDiskVolume.

To determine deduplication disk volume state

◆Display the volume state by using the following command:

UNIX: /usr/openv/netbackup/bin/admincmd/nbdevquery -listdv -stype PureDisk -U

Windows: install_path\NetBackup\bin\admincmd\nbdevquery -listdv -stype PureDisk -U

The state is either UP or DOWN. The following is example output

Disk Pool Name	: PD_Disk_Pool
Disk Type	: PureDisk
Disk Volume Name	: PureDiskVolume
Disk Media ID	: @aaaab
Total Capacity (GB) : 49.98
Free Space (GB)	: 43.66
Use%	: 12
Status	: UP
Flag	: ReadOnWrite
Flag	: AdminUp
Flag	: InternalUp
Num Read Mounts	: 0
Num Write Mounts	: 1
Cur Read Streams	: 0
Cur Write Streams	: 0
