–aw <percent>
This option was deprecated in the 2.3.1 release and will be changed or removed in a future
release.
Specifies the allocation warning threshold of the CPG. When the snapshot data space of the
virtual volume exceeds the specified percentage of the virtual volume size, an alert is
generated.
–al <percent>
Specifies the allocation limit threshold of the CPG. The snapshot data space is prevented
from growing beyond the specified percentage of the virtual volume size.
-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 between 4 to 8192 and 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 between 1 to 1024 and the default value
is 8.
NOTE: If the volume is not in any domain, then its retention time cannot exceed
the value of the system's
VVRetentionTimeMax. The default value for the
system's
VVRetentionTimeMax is 14 days. If the volume belongs to a domain,
then its retention time cannot exceed the value of the domain's
VVRetentionTimeMax, if set. The retention time cannot be removed or reduced
once it is set. If the volume has its retention time set, it cannot be removed within
its retention time. If both expiration time and retention time are specified, then
the retention time cannot be longer than the expiration time. This option
requires the 3PAR Virtual Lock License. Contact your local 3PAR Authorized
Service Provider for more information.
