drive.

Restarted

Connection
Persistence
Good
The target service
was able to
persist connection
information prior
to restarting.
Scheduled and
automatic snapshots
will occur normally.
Manual snapshots
can be taken
normally.
Target
Restarted
without
Connection
Persistence
Bad
The target service
has been
restarted and was
unable to persist
connection
information,
therefore,
operations that
were in the queue
have been lost.
An automatic snapshot
will be taken after the
target restarts, if the
target data was in a
good state prior to the
target restart and the
connection is
configured to auto-
remirror on auto-
reconnect.
Scheduled snapshots
will be delayed until the
target data is back in a
good state.
Start a mirror, wait
until it is complete
and the data is in a
good state, and
then take a manual
snapshot.
Restore
Required
Good
or
Bad
The data on the
target no longer
matches the data
on the source
because of a
failover. This does
not necessarily
mean that the data
on the target is
bad.
Scheduled and
automatic snapshots
will be delayed until a
restore is completed or
the Restore Required
state is overruled by a
mirror. Once the
restoration or mirror is
complete, automatic
and scheduled
snapshots will occur
normally.
Restore the target
data back to the
source or overrule
the Restore
Required state by
performing a
mirror. Once the
restoration or
mirror is complete,
manual snapshots
can be taken
normally.
