HP 3PAR InForm OS 3.1.1 Command Line Interface Reference
faster. Low priority indicates that the operation will run slower than the default priority task. This
option cannot be used with -halt option.
SPECIFIERS
<destination_volume | destination_volumeset>
Specifies the destination volume name or volume set name for the copy operation using up to 31
characters in length. The volume set name must start with set:.The destination volume (or each
member of the destination volume set) must be a writable base volume (not a snapshot) of equal
or greater size than a parent volume (if specified) and it must not be exported as a VLUN.
RESTRICTIONS
• The source and destination volumes must be writable.
• The destination volume cannot be exported as a VLUN before or during the createvvcopy
command process.
• The destination volume must be greater than or equal in size to the source volume.
• If both the destination and source are volume sets then they must contain the same number of
members.
• If the source is a volume set then the destination name can contain various patterns that are
used to form the copy volume name. See Help sub, vvnamepat for details. Note that the
time/date related patterns are not supported in this command.
• If the –s option is specified to save a snapshot for fast resynchronization and the snapshot
goes stale, the copy fails.
• A physical copy of a VV fails in any situation that a snapshot copy fails or when there is
insufficient snapshot space or I/O errors.
• If you create a Thinly-Provisioned Virtual Volume copy of a fully-provisioned virtual volume,
you cannot create a fully-provisioned copy of that TPVV at a later time. A fully-provisioned
virtual volume cannot be converted to a TPVV, then converted back to a full-provisioned virtual
volume.
EXAMPLES
The following example displays the creation of a copy of the VV vv1:
cli% createvvcopy –p vv1 vv2
Started copy. child=vv2 parent=vv1
Create a set of copies for the volumes in set vvcopyset, keeping snapshots around for quick
resyncronization:
cli% createvvcopy -s -p set:vvcopyset set:copys
Child Parent Status TaskID
s1 foo started 14
s2 bar started 15
s3 baz queued 16
Resynchronise the volumes in the volume set copys:
createvvcopy -r set:copys
Child Parent Status TaskID
s1 started 17
createvvcopy 157
