State changes in AdvancedDisk
If the mount status of a configured disk volume changes, the state of the disk volume within NetBackup will follow after a delay of about a minute. You can check the current state of a disk volume with the command nbdevquery - liststs - stype AdvancedDisk - U, as this example from a Windows server shows:
Storage Server : wstmas02 Storage Server Type : AdvancedDisk Storage Type : Formatted Disk, Direct Attached State : UP Flag : OpenStorage Flag : AdminUp Flag : InternalUp Flag : SpanImages Flag : LifeCycle Flag : CapacityMgmt Flag : FragmentImages Flag : Cpr Flag : RandomWrites Flag : FT-Transfer
The mount status is indicated by the InternalUp flag. If InternalUp is not shown, the disk volume is marked as DOWN in the output of the command nbdevquery - listdp - U as shown here:
Disk Pool Name : DPtest Disk Pool Id : DPtest Disk Type : AdvancedDisk Status : DOWN Flag : Patchwork Flag : Visible Flag : OpenStorage Flag : SingleStorageServer Flag : AdminDown Flag : InternalUp Flag : SpanImages Flag : LifeCycle Flag : CapacityMgmt Flag : FragmentImages Flag : Cpr Flag : RandomWrites Flag : FT-Transfer Raw Size (GB) : 4.00 Usable Size (GB) : 4.00 Num Volumes : 1 High Watermark : 98 Low Watermark : 80 Comment : Storage Server : wstmas02
The administrator can reset the state of the disk volume by issuing the command:
nbdevconfig - changestate - stype AdvancedDisk - dp <disk pool> -dv <disk volume> -state RESET
