Activity Switchover
When a failure occurs on the Media Gateway board, one of the following actions are
performed:
If the Redundant Media Gateway board is available, activity switchover to the
Redundant board is performed and service is restored on it. The failed board is
not automatically restarted until you explicitly perform an
Unlock
action on it. The
effect on the Media Gateway board's service depends on the Redundancy mode
available to the specific board prior to the failure. See 'Configuring Redundant
Media Gateway Board' on page
If the Redundant Media Gateway board is not available (it's either not configured
or is currently used for back-up for another board), the failed board is
automatically restarted. Service is typically restored on the failed board when it
completes the restart.
When the Media Gateway board fails and then there is an activity switchover to the
Redundant board, the operator should attend to the relevant Media Gateway and
perform the following maintenance tasks:
Identify the reason for the failure, collect relevant logs and record all maintenance
or operational events that preceded the failure.
Lock
and
unlock
the failed Media Gateway board. Wait until the board's
Operational State
is changed to
Enabled
– this indicates that the board is ready
for operation.
Perform
SwitchBack
action to switch activity back from the Redundant board to
the regular board.
Wait until the Redundant board completes restart and its
Operational State
is
changed to
Enabled
.
Open the Board's Redundancy screen and verify the Redundancy modes for all
regular Media Gateway boards.
