# Class CIM_StorageVolume
extends CIM_StorageExtent

A StorageVolume is a StorageExtent that is published for use outside of the scoping System. For SCSI storage target devices, StorageVolumes are used to represent target Block devices, (peripheral device type codes 0h (i.e, direct-access), 4h (i.e., write-once), 5h (i.e., CD/DVD), 7h (i.e., optical memory), and Eh (i.e., simplified direct-access).); Stream devices, (peripheral device type codes 1h (i.e., sequential-access) and 3h (i.e., processor).). In these case, StorageVolume.Name will be derived from SCSI volume as documented in StorageExtent.Nameformat and NameNamespace Descriptions. The 'Exported' value from StorageExtent.ExtentStatus[] MUST be in all instances of StorageVolume to maintain the semantic of 'published' described above.

Description

A StorageVolume is a StorageExtent that is published for use outside of the scoping System. For SCSI storage target devices, StorageVolumes are used to represent target Block devices, (peripheral device type codes 0h (i.e, direct-access), 4h (i.e., write-once), 5h (i.e., CD/DVD), 7h (i.e., optical memory), and Eh (i.e., simplified direct-access).); Stream devices, (peripheral device type codes 1h (i.e., sequential-access) and 3h (i.e., processor).). In these case, StorageVolume.Name will be derived from SCSI volume as documented in StorageExtent.Nameformat and NameNamespace Descriptions. The 'Exported' value from StorageExtent.ExtentStatus[] MUST be in all instances of StorageVolume to maintain the semantic of 'published' described above.
