Properties option in the Change Storage Units dialog box

Click Properties to display information about the volume or the disk pool, as follows:

Note:

The following properties do not apply to cloud storage disk pools: Available space, Capacity, High water mark, Low water mark, Raw size, and Usable size.

All these values are derived from the storage capacity, which cannot be fetched from the cloud provider.

Table: Storage Units Properties

Property	Description
Available space	This value reflects the space that remains for storage on a disk storage unit. The following equation determines the available space: Available space = free space + potential free space - committed space The df command may report a value for the available space that is slightly different from the actual free space value that appears as a result of the nbdevquery command: nbdevquery -listdv -stype server_type -dp disk_pool The available space that the df command lists does not include the space that the operating system reserves. Since NetBackup runs as root, the nbdevquery command includes the reserved space in the available space equation.
Capacity	The Capacity value reflects the total amount of space that the disk storage unit or pool contains, both used and unused.
Disk pool comments	Comments that are associated with the disk pool.
High water mark	The high water mark for the disk pool applies to both the individual disk volumes in the pool and the disk pool: Individual volumes When a disk volume reaches the high water mark, new jobs are not assigned to the volume. This behavior happens for all disk types except BasicDisk staging storage units. The high water mark event triggers the deletion of images that have been relocated, attempting to bring the used capacity of the disk volume down to the low water mark Disk pool When all volumes are at the high water mark, the disk pool is full. When a disk pool approaches the high water mark, NetBackup reduces the number of jobs that are allowed to write to the pool. NetBackup does not assign new jobs to a storage unit in which the disk pool is full. The default setting is 99%.
Low water mark	The low water mark for the disk pool. Once a disk volume fills to its high water mark, NetBackup attempts to delete enough relocated images to reduce the used capacity of the disk volume down to the low water mark. The low water mark setting cannot be greater than the high water mark setting. Note: The Low water mark setting has no effect unless backups are written through a storage lifecycle policy, using the capacity-managed retention type.
Name	The name of the disk pool.
Number of volumes	The number of disk volumes in the disk pool.
% full	The percentage of storage that is currently in use on the volume. The df command may report a percentage used (Use%) value that is different from the % full value. (See the preceding Available Storage topic for a description of why the values appear differently.)
Raw size	The raw, unformatted size of the storage in the disk pool.
Usable size	The amount of usable storage in the disk pools.
