creategroupvvcopy
DESCRIPTION
The creategroupvvcopy command creates consistent group physical copies of a list of virtual
volumes.
SYNTAX
The syntax for the creategroupvvcopy command can be one of the following:
• creategroupvvcopy -p [options] <parent_VV>:<destination_VV>...
• creategroupvvcopy -r [options] <destination_VV>...
• creategroupvvcopy -halt <destination_VV>...
AUTHORITY
• Super, Edit
• Any role that is granted the groupvvcopy_create right.
OPTIONS
–p
Starts a copy operation from the specified parent volume (as indicated using the <parent_VV>
specifier) to its destination volume (as indicated using the <destination_VV> specifier). First a
set of consistent group snapshots of all the <parent_VV> specifiers are taken and then each
snapshot is copied to the corresponding <destination_VV> specifier. After the copies are
complete, the snapshots are deleted unless the -s option is specified. Each <parent_VV> specifier
must be a base virtual volume or a read/write snapshot.
–r
Resynchronizes the set of destination volumes (as indicated using the <destination_VV> specifier)
with their respective parents using saved snapshots so that only the changes made since the last
copy or resynchronization are copied. The resynchronization operation can only be performed if
snapshots of the parents saved using the -s option in an earlier instance of the creategroupvvcopy
command are present. These old snapshots are replaced by a new set of consistent group snapshots
for the next resynchronization operation (such as the –s option need not be specified with the –r
option).
–halt
Cancels an ongoing physical copy. This causes the destination volume (as indicated using the
<destination_VV> specifier) to be marked with the 'cpf' status, which can be cleared up when
a new copy is started.
–s
Saves snapshots of the parent volume (as indicated with the <parent_VV> specifier) for quick
resynchronization and to retain the parent-copy relationships between each parent and destination
volume. The -s option is implied and need not be specified when the -r option is used. Each
<destination_VV> specifier remains marked as a physical copy of its <parent_VV> specifier
until it is promoted to a base virtual volume using the promotevvcopy command, which also
removes the saved snapshot of the <parent_VV> specifier. The saved snapshots should not be
removed manually. If the same <parent_VV> specifier is copied to different <destination_VV>
specifiers with the -s option, a different snapshot of the <parent_VV> specifier is saved for
each <destination_VV> specifier.
