If this option is selected on UNIX, the current
configuration of the participating volume groups is
Check the data configuration

compared with the volume group configuration
during the backup session kept in XPDB. If the
configuration changed since then, the restore fails.
When performing instant recovery in an
MC/ServiceGuard cluster to another node (not the
one that was backed up), leave this option selected.
The current volume group configuration on the node
to which instant recovery is being performed is
different from the configuration kept in XPDB. With
this option selected, XPDB volume group
configuration is replaced by the current configuration
on the node to which instant recovery is being
performed, and the session is not aborted.
Default: selected.
LDEV pairs, involved in the current instant recovery
session, are left in the SUSPENDED state after restore.
Keep the replica after the
restore/-keep_version
If not selected, the LDEV pairs are left in the PAIR
state.
Default: selected.
Instant recovery and LVM mirroring
If you use an LVM mirroring configuration, perform the following before instant
recovery:
1. Reduce all logical volumes which have LVM mirrors, specifically, reduce or
remove the mirrors that reside on LDEVs that do not have physical XP mirrors.
This ensures that restored data cannot be accidentally overwritten by a
synchronization of the LVM mirror.
Rebuild the LVM mirroring environment to the previous configuration.
2. Start instant recovery.
