(1 of 3 in the source DR group)
A DR group log is a designated virtual disk in a source DR group that is used under certain
circumstances to temporarily store host writes to source virtual disks. Logging can be started
automatically when remote replication to the destination DR group cannot be performed, for
example when a remote link is down. Logging can also be started on demand by performing a
suspend action from the GUI, jobs, or a CLUI command. When remote replication is re-established,
the contents of the source DR group log are written to the destination virtual disks. See DR groups
Logs.
Home group and home configuration
When designated as a home group, the group is considered be the preferred source in the remote
replication relationship. By default, the property for the source and destination DR group is set true
and false, respectively. This is called the home configuration. See DR groups Home.
DR group names
When a DR group pair is created, the same DR group name is assigned to the source and
destination DR group.
IMPORTANT: After creation, HP recommends that you edit partner DR groups and change the
names.
