Specifies that the volume snapshot space is to be provisioned from the specified CPG. This option
moves all the logical disks currently contained in the snapshot 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 in this option. If the <snp_CPG> specifier is specified as "", the volume snapshot
space is longer provisioned from a CPG and the existing snapshot space logical disks are removed
from the CPG. This is permitted only when the existing snapshot logical disks are exclusively used
by the volumes specified in this option.
-snp_aw <percent>
NOTE: The operation of setting a snapshot space CPG for a tpsd volume (a TPVV created with
HP 3PAR OS 2.2.4 or earlier) is not permitted if the volume has existing snapshots. All existing
snapshots must first be removed before using this option.
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.
pol <policy>[,<pol>...]
Specifies the policy is implemented by a virtual volume. Valid policies are as follows:
stale_ss - Specifies that invalid (stale) snapshot volumes are permitted. Failures to update
snapshot data occur when there is not sufficient administration or snapshot space. Failures to
update snapshot data does not affect the write to the base volume. However, the snapshot is
considered invalid.
no_stale_ss - Specifies that stale snapshot volumes are not permitted. A failure to update
a snapshot is considered a failure to write to the base volume. Existing stale snapshots remain
stale.
one_host - Constrains the export of a volume to one host or one host cluster (when cluster
names may be used as a host name).
no_one_host - This policy should only be used when exporting a virtual volume to multiple
hosts for use by a cluster-aware application, or when “port presents” VLUNs are used. This is
the default policy setting.
tp_bzero - Specifies that if a host write results in the allocation of a new data page that is
only partially filled by the host write, then a zero-fill is performed on the unwritten portion of
the data page to ensure that the host cannot read data from deleted volumes or snapshot. The
default allocation page size is 16 KB.
no_tp_bzero - Specifies that the zero-fill operation is bypassed on the allocation of partially
written data pages.
zero_detect - Enables the HP 3PAR storage system to scan for zeros in the incoming write
data. When used during a physical copy to a Thinly Provisioned Virtual Volume (TPVV) avoids
allocating space for blocks containing zero. When used with a Thin Persistence license,
reclaims allocated space when zero blocks are written to a TPVV. This policy is applicable
for base TPVVs.
no_zero_detect - Disables the HP 3PAR storage system 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 <percent>
