Volumes table in the Volumes topic

The volumes table shows the following information. By default, the table shows 10 entries at a time.

• Group – Shows the group name if the volume is grouped into a volume group; otherwise, --.

• Name – Shows the name of the volume.

• Pool – Shows whether the volume is in pool A or B for virtual pools or pool-name for linear pools.

• Type – Shows whether the volume is a base volume (virtual), standard volume (linear), or a snapshot (virtual).

• Size – Shows the storage capacity defined for the volume when it was created, minus 60 KB for internal use.

• Allocated – Shows the storage capacity allocated to the volume for written data.

NOTE:

When selecting one or more volumes or snapshots in the volumes table, the Snapshots, Maps, Replication Sets,

and Schedules tabs are enabled if they have associated information for the selected items.
