7.5.15 Dealing with server failures that disable restart and hot standby processing (server in the monitor mode)

In the event of a failure on a server in the monitor mode, if automatic restart and hot standby processing cannot be performed, the server status remains under execution processing in the HA Monitor. In such a case, restart the active server or perform hot standby processing with the procedure described here.

If you want to restart the active server:

1. On the active system, execute the monitor-mode server termination command (monend command) to terminate the active server.

2. On the active system, execute the monitor-mode server start command (monbegin command) to start the active server.

3. On the standby system, execute the monitor-mode server start command (monbegin command) to start the standby server.

If you want to perform hot standby processing:

Use one of the following methods to perform hot standby processing:

Method 1

1. On the standby system, execute the monitor-mode server start command (monbegin command) to start the standby server.

2. On the active system, execute the server hot-standby switchover command (monswap command) to perform planned hot-standby switchover.

3. On the same host as in step 2, execute the monitor-mode server start command (monbegin command) to start the standby server.

Method 2

1. On the active system, execute the monitor-mode server termination command (monend command) to terminate the active server.

2. On the standby system, execute the monitor-mode server start command (monbegin command) to start the standby server.

3. On the standby system, execute the wait-state server start command (monact command) to start the server in start wait state as the active server.

4. On the same host as in step 1, execute the monitor-mode server start command (monbegin command) to start the standby server.
