Property	Description
Disk volume	For a media server deduplication pool, all disk storage is exposed
	as a single volume.
	PureDiskVolume is a virtual name for the storage that is
	contained within the directories you specified for the storage path
	and the database path.
Available space	The amount of space available in the disk pool.
Raw size	The total raw size of the storage in the disk pool.
Comment	A comment that is associated with the disk pool.
High water mark	The high water mark is a threshold that indicates the
	PureDiskVolume is full. When the PureDiskVolume is at the
	high water mark, NetBackup fails any backup jobs that are
	assigned to the disk pool storage unit.
	NetBackup also fails backup jobs if the PureDiskVolume does not
	contain enough storage for its estimated space requirement.
	NetBackup again assigns jobs to the storage unit when the capacity
	of the PureDiskVolume drops below the high water mark. Capacity
	is regained as backup images expire.
	NetBackupdoes not assign backup jobs to the disk pool if used
	space in the PureDiskVolume is greater than the high water mark.
	The default is 98%.
Low water mark	The low water mark has no affect on the PureDiskVolume.
	The low water mark setting cannot be greater than or equal to the
	high water mark setting.
	The default is 80%
