CLI Guide

snapshots to delete. Snapshots are considered to be eligible for deletion if they have any retention priority
other than never-delete. Eligible snapshots are considered for deletion by priority and age. The oldest, lowest
priority snapshots are deleted first. Snapshots that are mapped or are not leaves of a volume’s snapshot tree
are not eligible for automatic deletion.

Parameters
access read-write|rw|read-only|ro|no-access
Optional. The access permission to use for the mapping: read-write (rw), read-only (ro), or no-
access. If no-access is specified, the volume is not mapped. The default is read-write
Optional. For a virtual volume, this sets whether the system will try to allocate pages in a sequentially
optimized way to reduce I/O latency in SSD applications and improve performance.
• disabled or off: Optimized page allocation is disabled. This is the defaullarge-virtual-extents
enabled|disabled|on|offt.
• 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 volume size is 140 TB (128 TiB).
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
