COMMAND
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
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).
