The Volume Overview table shows: • The capacity and space usage of the volume • The quantity of mappings for the volume • The quantity of task schedules for the volume • As described in Viewing replication properties, addresses, and images for a volume on page 121: the quantities of replication addresses and replication images for the volume For descriptions of storage-space color codes, see About storage-space color codes on page 33. Select a component to see more information about it. Volume properties When you select the Volume component, the Properties for Volume table shows: • Vdisk Name. Name of the vdisk that the volume is in. • Name. Volume name. • Size. Volume size. • Preferred Owner. Controller that owns the vdisk and its volumes during normal operation. • Current Owner.

If the volume is being created by a volume-copy operation, the percent complete. • Volume Description. For OpenVMS, a numeric value (set in SMU) that identifies the volume to an OpenVMS host. For HP-UX, a text value (set in-band by a host application) that identifies the volume. Blank if not set.

on page 121: the
quantities of replication addresses and replication images for the volume
For descriptions of storage-space color codes, see
About storage-space color codes
on page 33.
Select a component to see more information about it.
