exceeds the high threshold value, the host loses read and write access to the pool volumes. The

only way to regain read and write access to the pool volumes is to add more storage to the pool.

snapshot-retention-priority never-delete|high|medium|low

Optional. For virtual storage, this specifies the retention priority for snapshots of the volume set.

● never-delete: Snapshots will never be deleted.

● high: Snapshots may be deleted after all eligible medium-priority snapshots have been deleted

● medium: Snapshots may be deleted after all eligible low-priority snapshots have been deleted.

This is the default.

● low: Snapshots may be deleted.

tier-affinity no-affinity|archive|performance

Optional. For virtual storage, this specifies how to tune the tier-migration algorithm for the volume:

● no-affinity: This setting uses the highest available performing tiers first and only uses the

Archive tier when space is exhausted in the other tiers. Volume data will swap into higher

performing tiers based on frequency of access and tier space availability. This is the default.

● archive: This setting prioritizes the volume data to the least performing tier available. Volume

data can move to higher performing tiers based on frequency of access and available space in the

tiers.

● performance: This setting prioritizes volume data to the higher performing tiers. If no space

is available, lower performing tier space is used. Performance affinity volume data will swap into

higher tiers based upon frequency of access or when space is made available

vdisk vdisk

Optional; required for linear volumes. The name or serial number of the linear disk group in which to

create the volumes. A name that includes a space must be enclosed in double quotes.

volume-group volume-group

Optional. The name of a volume group to which to add the volume. A name that includes a space

must be enclosed in double quotes. If the group does not exist, it will be created

Examples

Create two unmapped, 100 GB volumes with base name MyVol- in pool B and add them to volume

group MyVG.

# create volume-set count 2 size 100GB pool b basename MyVol- volume-

group MyVG

Create two unmapped, 100 GB volumes with base name data- in disk group data.

# create volume-set count 2 size 100GB vdisk data basename data-

Create ten 20-GB volumes with the base name vd1_v in disk group vd1, mapped starting with LUN

5 with read-only access through port A1.

# create volume-set count 10 size 20GB vdisk vd1 basename vd1_v baselun

5 access ro ports a1

Create four 5 MB volumes with the base name BV1_ with snapshot retention priority high.

# create volume-set pool B count 4 size 5MB basename BV1_ snapshot-
