HP 3PAR OS 3.1.3 Command Line Interface Reference

SPECIFIERS
<copy_of_VV>
Specifies the name of the Virtual Volume being copied (the parent volume).
<snapshot_VV>
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 HP 3PAR Virtual Copy license. Contact your local HP 3PAR
representative for information.
EXAMPLES
In the following example, virtual volumes VV1 and VV2 are created using the createaldvv
command. Then the creategroupsv command is used to create a read-only snapshot of each of the
volumes and display a list of the snapshots:
cli% createvv -snp_cpg cpg1 cpg1 VV1 4g
cli% createvv -snp_cpg cpg1 cpg1 VV2 4g
cli% creategroupsv ro VV1 VV2
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 500 virtual copies per volume are allowed.
