HP 3PAR OS 3.1.3 Command Line Interface Reference

-snp_cpg <snp_CPG>
Specifies the name of the CPG from which the snapshot space is allocated.
-snp_aw <percent>
Enables a snapshot space allocation warning. A warning alert is generated when the reserved
snapshot space of the VV exceeds the indicated percentage of the VV size.
-snp_al <percent>
Sets a snapshot space allocation limit. The snapshot space of the VV is prevented from growing
beyond the indicated percentage of the VV size.
The following options can be used when creating Thinly Provisioned Virtual Volumes (TPVVs):
-tpvv
Specifies that the volume should be a TPVV.
-usr_aw <percent>
This option enables user space allocation warning. It specifies that a warning alert is generated
when the reserved user space of the TPVV exceeds the specified percentage of the VV size.
-usr_al <percent>
This option sets the user space allocation limit. The user space of the TPVV is prevented from
growing beyond the indicated percentage of the VV size. After this size is reached, any new writes
to the VV will fail.
SPECIFIERS
<usr_CPG>
Specifies the name of the CPG from which the volume user space will be allocated. If the -tpvv
option is specified, the volume is thinly provisioned. Otherwise, the volume is fully provisioned
from the specified CPG. If the name of the CPG is to be taken from a template, this field should
be (–).
<VV_name> [.<index>]
Specifies a VV name up to 31 characters in length. If the -cnt option is used, the optional decimal
number <index> specifies the name of the first VV (<vvname>.<index>). The <index> is
incremented by 1 for each subsequent VV. The <index> must be an integer from 0 through 999999.
All VVs have the same length constraint.
<size>[g|G|t|T]
Specifies the size for the volume in MB. The volume size is rounded up to the next multiple of 256
MB. The size should be an integer. An optional suffix (with no whitespace before the suffix) will
modify the units to GB (g or G suffix) or TB (t or T suffix). If the size is to be taken from a template,
this field should be (-).
RESTRICTIONS
• Access to all domains is required to run this command with logical disks specified.
• Use of this command with the -tpvv option requires a Thin Provisioning license. Contact your
local HP 3PAR representative for information.

Volumes with the -tpvv option.
