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

SPECIFIERS
<SV_name>
Specifies the snapshot name, using up to 31 characters in length.
<copy_of_VV | VV_set>
Specifies the parent volume name or volume set name, using up to 31 characters in length. The
VV_set name must start with set:. If copy_of_VV is a VV_set then svname can contain
various patterns that are used to form the snapshot volume name. See Help sub,vvnamepat for
details.
RESTRICTIONS
• Use of this command requires a HP 3PAR Virtual Copy license. Contact your local HP 3PAR
representative for information.
• A read-only snapshot of a read-only source volume is not allowed.
• A read/write snapshot of a read/write snapshot or base is not allowed.
EXAMPLES
The following example creates a read-only snapshot volume svro_vv0 from volume vv0:
cli% createsv –ro svr0_vv0 vv0
The following example creates snapshot volume svrw_vv0 from the snapshot svro_vv0:
cli% createsv svrw_vv0 svro_vv0
The following example creates a snapshot volume for each member of the VV set vvcopies.
Each snapshot will be named svro-<name of parent volume>:
cli% createsv -ro svro-@vvname@ set:vvcopies
If vvcopies contained VVs named vv.0, vv.1 and vv.2 this would result in snapshots named
svro-vv.0, svro-vv.1 and svro-vv.2.
NOTES
• A maximum of 256 writable virtual copies per volume are allowed.
• A maximum of 500 virtual copies per volume are allowed.
• For the VV_set option, the createsv command creates consistent group snapshots of the
VVs in the set. Consistent group snapshots are all created at the same point in time so that
related structures on different volumes in the set remain consistent.
