CLI Guide

● enabled or on: Optimized page allocation is enabled.
lun LUN
Optional if the access parameter is set to no-access. Specifies the LUN to assign to the mapping
on all ports.
pool pool
Optional for linear volumes. Required for virtual volumes. The name or serial number of the pool in
which to create the volume.
ports ports
Optional. The ports through which the host can access the volume. All specified ports must be the
same type (FC, for example). For port syntax, see Command syntax. If this parameter is omitted, all
ports are selected.
reserve size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB]
Optional. Linear storage only. Specifies the size of the snap pool to create in the disk group. The
unit is optional (B represents bytes). If base 2 is in use, whether you specify a base-2 or base-10
unit, the resulting size will be in base 2. If no unit is specified, the default is 512-byte blocks. If this
parameter is omitted, the size will be either 20% of the volume size or 5.37 GB, whichever is larger.
The recommended minimum size for a snap pool is 50
size size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB]
Sets the volume size. The unit is optional (B represents bytes). If base 2 is in use, whether you specify
a base-2 or base-10 unit, the resulting size will be in base 2. If no unit is specified, the default is
512-byte blocks.
A value less than 4.2 MB (4 MiB) will be increased to that size. A value greater than 4 MB will be
decreased to the nearest 4 MB boundary. The maximum size of a virtual volume is 140 TB (128 TiB).
The maximum size of a linear volume is equal to the maximum size limit of the disk group.
If overcommit is enabled, the size can exceed the physical capacity of the storage pool. To see
whether overcommit is enabled, use the show pools command.
● When the overcommit feature is disabled, the host does not lose read or write access to the pool
volumes when the pool reaches or exceeds the high threshold value.
● When the overcommit feature is enabled, the storage system sends the data protect sense key
Add, Sense: Space allocation failed write protect to the host when the pool
reaches or exceeds the high threshold value. If the host is rebooted after the pool reaches or
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.
● 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.
