CLI Guide

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

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

• 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

volume. 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.

name

A name for the new volume. The name must be unique system-wide. Input rules:

• The value is case sensitive.

• The value can have a maximum of 32 bytes.

• The value can include spaces and printable UTF-8 characters except: " , . < \

• A value that includes a space must be enclosed in double quotes.

Examples

Create the 20-GB volume V1 in disk group VD1, and map it to ports A1 and B1 using LUN 5.

# create volume vdisk VD1 size 20GB ports a1,b1 lun 5 V1

Create a 100-GB standard volume named MyVolume in pool A, map it to use LUN 5 with read-write access

through port 1 in each controller, add it to volume group MyGroup, and tune tier-migration for performance.

# create volume MyVolume pool A size 100GB access rw lun 5 ports 1 volume-

group MyGroup tier-affinity performance

Create a 20-GB standard volume named Secrets in storage pool A, and map it to use LUN 333 with read-

only access through all ports.

# create volume Secrets pool A size 20GB lun 333 access read-only

Create volume Vol1 with snapshot retention priority high.

# create volume snapshot-retention-priority high Vol1
