Storage Volume node

A Storage Volume node represents a block of storage which a client can access.

Creation/update

A Storage Volume node is created or updated when a storage entity is discovered by one of the following:

WBEM queries to storage management software triggered by the creation or update of an SI representing storage management software
Directly discovered storage using WBEM queries to the WBEM/SMI-S provider triggered by the creation or update of a Storage Device node representing the chassis
Directly discovered storage using SNMP triggered by the creation or update of a Storage Device node representing the chassis

A Storage Volume node is removed when its parent Storage System node is removed. This is Containment Removal.

The attributes of a Storage Volume node are as described in the following table:

UI Name Attribute Name and Type	Description
Not displayed in UI `key string`	Key of the volume.
Volume ID `volume_id string`	Identity of the volume.
Type `type string`	Type of the volume.
NAA ID `naa_id string`	NAA ID (WWN).
Name `name string`	Name of the volume.
Block Size `block_size int`	Block size.
Number of Blocks `num_blocks int`	Number of blocks.
Consumable Blocks `consumable_blocks int`	Consumable blocks.
Consumed From Pool `consumed_capacity int`	Amount of capacity that has been consumed in the parent pool. For thin volumes, this value will typically be less than the visible capacity; for traditional volumes this value equals, or is greater than, the visible capacity.
Thinly Provisioned `thinly_provisioned boolean`	Indicates a thinly provisioned volume.
RAID Level `raid_level string`	RAID level.
Mapped `mapped boolean`	Indicates that the volume is mapped to a client.
