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] :... • creategroupvvcopy -r [options] ... • creategroupvvcopy -halt ... 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 specifier) to its destination volume (as indicated using the specifier). First a set of consistent group snapshots of all the specifiers are taken and then each snapshot is copied to the corresponding specifier. After the copies are complete, the snapshots are deleted unless the -s option is specified. Each specifier must be a base virtual volume or a read/write snapshot. -r Resynchronizes the set of destination volumes (as indicated using the 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 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 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 specifier remains marked as a physical copy of its specifier until it is promoted to a base virtual volume using the promotevvcopy command, which also removes the saved snapshot of the specifier. The saved snapshots should not be removed manually. If the same specifier is copied to different specifiers with the -s option, a different snapshot of the specifier is saved for each specifier. -b creategroupvvcopy 119
