HP 3PAR OS 3.1.3 Command Line Interface Reference

createsv
DESCRIPTION
The createsv command creates a point-in-time (snapshot) copy of a virtual volume. Create
snapshots to perform such tasks as backing up data on the base volume and allowing multiple
copies of a base volume to be modified without affecting the original base volume
SYNTAX
createsv [options] <SV_name> <copy_of_VV | VV_set | RC_group>
AUTHORITY
• Super
• Any role that is granted the sv_create right.
OPTIONS
–ro
Specifies that the copied volume is read-only. If not specified, the volume is read/write.
–i <VV_ID>
Specifies the ID of the copied VV. This option cannot be used when VV set is specified.
—rcopy
Specifies that synchronous snapshots be taken of a volume in a remote copy group. The same
snapshot <SV_name> will be applied on both the primary and secondary arrays.
-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.
-noblock
When a read-only snapshot is taken, the storage system blocks host I/O to the parent virtual volume
while the snapshot is being created. If the -noblock option is specified, the storage system will not
