Disables the InServ Storage Server to scan for zeros in the incoming write data to
reclaim allocated space on the volume.
Multiple policies can be specified and are separated with commas. If a policy is not
specified, the policy defaults to stale_ss .
The following options can only be used on Thinly Provisioned Virtual Volumes (TPVVs):
-usr_aw
This option returns a user space allocation warning. It generates a warning alert when the
user space of the TPVV exceeds the specified percentage of the virtual volume size.
-usr_al
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
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
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 1024 . The default value is 8 .
The following options can only be used on fully provisioned volumes:
-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 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.
