Automatically creating target volumes on the, Secondary system – HP 3PAR Operating System Software User Manual

•
-snp_cpg
—The local snapshot CPG
and target snapshot CPG that will be used for volumes that are autocreated
•
—Name of the volume group
To unset all user and snapshot CPGs that are associated with the volume group, issue the
setrcopygroup
command with the cpg subcommand and -usr_cpg_unset and
-snp_cpg_unset
options, as follows:
# setrcopygroup cpg -usr_cpg_unset -snp_cpg_unset
Automatically Creating Target Volumes on the Secondary System
To create a volume automatically on the secondary storage system, the primary volume must first
be created on the source system. On the source system, issue the admitrcopyvv command with
the -createvv option, as follows:
# admitrcopyvv [options] -createvv
where:
•
-nosync
(option)—Specifies that the volume should skip the initial sync. This is for the
admission of volumes that have been pre-synced with the target volume. This specifier cannot
be used when starting snapshots (
•
-createvv
—Specifies that the secondary volumes should be created automatically on the
target using the CPG associated with the remote-copy group on that target.
•
—An optional read-only snapshot
can be specified along with the virtual volume name
is a starting snapshot. When the group is started, a full synchronization is not performed.
Instead, for synchronous groups, the volume will synchronize deltas between
and the base volume. For periodic groups, the volume will synchronize deltas between
and a snapshot of the base.
CAUTION:
The
volume would contain only changes, not a fully synchronized copy of the primary volume.
•
—The target name associated with the volume group
and secondary volume name
Issue the showrcopy -d command to view the associated local and target CPG information and
all target volumes that are automatically created.
NOTE:
The target volume is created using the same volume WWN as the primary volume.
Automatically Deleting Target Volumes on the Secondary System
NOTE:
When using the -removevv option, primary volumes are not deleted; only secondary
side volumes are deleted.
To automatically delete the volumes on the secondary storage system, issue the dismissrcopyvv
command with the -removevv option:
# dismissrcopyvv -removevv
