Veritas NetBackup™ Deduplication Guide

MSDP volume state changes to DOWN when volume is unmounted

If a volume becomes unmounted, NetBackup changes the volume state to DOWN. NetBackup jobs that require that volume fail.

To determine the volume state

  • Invoke the following command on the master server or the media server that functions as the deduplication storage server:

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

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

    The following example output shows that the DiskPoolVolume is UP:

    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
    Num Repl Sources    : 0
    Num Repl Targets    : 0
    WORM Lock Min Time  : 0
    WORM Lock Max Time  : 0

To change the volume state to UP

  1. Mount the file system

    After a brief period of time, the volume state changes to UP. No further action is required.

  2. If the volume state does not change, change it manually.
