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

Specifies the priority of the copy operation when it is started. This option allows the user to control
the overall speed of a particular task. If this option is not specified, the createvvcopy operation
is started with default priority of medium. High priority indicates that the operation will complete
faster. Low priority indicates that the operation will run slower than the default priority task. This
option cannot be used with -halt option.
-online
Specifies that the copy is to be performed online. The destination can be immediately exported
and is automatically created by this command, meaning that it cannot exist prior to executing this
command. This option requires the specification of a CPG for the destination volume and allows
for the -snp_cpg and -tpvv options. The -online option requires the -p option and cannot
be used with the -r, -halt, -s, -b, and -pri options.
SPECIFIERS
<destination_cpg>
Specifies the destination CPG to use for the destination volume if the -online option is specified.
<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.
• A Thinly Provisioned Virtual Volume cannot be reverse-copied to a Commonly Provisioned
Virtual Volume. That is, you cannot create a reversed copy from a TPVV to a CPVV after
creating a copy from a CPVV to a TPVV using the same volumes.
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
createvvcopy 159
