HP 3PAR OS 3.1.3 Command Line Interface Reference

Indicates a snapshot space allocation warning. Through this option you can generate a warning
alert when the reserved snapshot space of the virtual volume exceeds the indicated percentage
of the virtual volume size.
-snp_al <percent>
Indicates a snapshot space allocation limit. The snapshot space of the virtual volume is prevented
from growing beyond the indicated percentage of the virtual volume size.
The following option can only be used on fully provisioned volumes:
-usr_cpg <usr_cpg>
Specifies that the volume user space that is to be provisioned from the specified CPG. This option
moves all the logical disks currently contained in the user space for these volumes into the CPG.
This is permitted only when none of the logical disks are shared with other volumes that are not
specified with this option. If the <usr_CPG> specifier is specified as "", the volume user space is
no longer provisioned from a CPG and the existing user space logical disks will be removed from
the CPG. This is permitted only when the existing user’s logical disks are exclusively being used
by the volumes specified with this option.
The following options can only be used on Thinly Provisioned Virtual Volumes (TPVVs):
-usr_aw <percent>
This option returns a user space allocation warning. It generates a warning alert when the reserved
user space of the TPVV exceeds the specified percentage of the virtual volume size.
-usr_al <percent>
This option returns the user space allocation limit. The user space of the TPVV is prevented from
growing beyond the indicated percentage of the virtual volume size. After this size is reached,
any new writes to the virtual volume will fail.
-spt <sectors_per_track>
Defines the virtual volume geometry sectors per track value that is reported to the hosts through the
SCSI mode pages. The valid range is from 4 to 8192. The default value is 304.
-hpc <heads_per_cylinder>
Defines the virtual volume geometry heads per cylinder value that is reported to the hosts though
the SCSI mode pages. The valid range is from 1 to 255. The default value is 8.
SPECIFIERS
<VV_name|pattern>...
Specifies the virtual volume name or all virtual volumes that match the pattern specified, using up
to 31 characters. The patterns are glob-style patterns. Valid characters include alphanumeric
characters, periods, dashes, and underscores.
RESTRICTIONS
At least one option must be specified.
EXAMPLES
The following example sets the policy of virtual volume vv1 to no_stale_ss.
# setvv –pol no_stale_ss vv1
The following example changes the name from test to newtest.
cli% setvv -name newtest test
setvv 335
