HP 3PAR InForm OS 3.1.1 Command Line Interface Reference

Optional name of the snapshot Virtual Volumes. If <snapshot_VV> is not specified, the system
tries to automatically generate the snapshot name of the form <copy_of_VV>.<type><number>
where <type> is either ro or rw and <number> is either empty or the lowest number starting
from 0 that does not conflict with an existing volume name. If the generated name is too long
(because the <copy_of_VV> name is too long) the command will fail, and the user is required
to specify <snapshot_VV> explicitly.
[<ID>]
Optional ID of the <snapshot_VV>. If the <ID> is not specified, an ID is chosen automatically.
RESTRICTIONS
Use of this command requires a Virtual Copy license. Contact your local 3PAR representative for
information.
EXAMPLES
In the following example, Virtual Volumes VV1 and VV2, and their underlying logical disks are
created using the createaldvv command. A read-only snapshot of the volumes is then taken
and a list of the volumes is generated using the creategroupsv command:
cli% createaldvv –pct 10 VV1 4g
cli% createaldvv –pct 10 VV2 4g
cli% creategroupsv –ro VV1 VV2
CopyOfVV SnapshotVV
VV1 VV1.ro
VV2 VV2.ro
NOTES
• Consistent group snapshots are all created at the same point in time so that related structures
on different volumes in the group remain consistent.
• A maximum of 256 writable virtual copies per volume are allowed.
• A maximum of 2048 virtual copies per volume are allowed.
