HP 3PAR Command Line Interface Reference (OS 3.1.2 MU2) (QL226-97016, June 2013)

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.
-snp_aw <percent>
Enables a snapshot space allocation warning. A warning alert is generated when the 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.
-spt <sectors_per_track>
Defines the VV 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 VV geometry heads per cylinder value that is reported to the hosts though the SCSI
mode pages. The valid range is between 1 to 255 and the default value is 8.
-exp <time>[d|D|h|H]
Specifies the relative time from the current time that volume will expire. <time> is a positive integer
value and in the range of 1 - 43,800 hours (1,825 days). Time can be optionally specified in days
or hours providing either d or D for day and h or H for hours following the entered time value.
-comment <comment>
Specifies any additional information up to 511 characters for the volume.
-f
Do not ask for confirmation before creating a volume with retention time (-retain).
-retain <time>[d|D|h|H]
Specifies the amount of time, relative to the current time, that the volume will be retained. <time>
is a positive integer value and in the range of 1 - 43,800 hours (1,825 days). Time can be
optionally specified in days or hours providing either d or D for day and h or H for hours following
the entered time value.
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 HP 3PAR Virtual Lock License. Contact your local HP 3PAR Authorized
Service Provider for more information.
• The following defines the volume policy:
–pol <pol>[,<pol>...]
Specifies VV policies.
stale_ss
Specifies that invalid snapshot volumes are permitted. Failure to update snapshot data does not
affect the write to the base volume, but the snapshot is considered invalid.
no_stale_ss
Specifies that invalid snapshot volumes are not permitted. Failure to update a snapshot is considered
a failure to write to the base volume.
