10.3.2.2 Procedure for Applying Correction by Rolling Update

This section explains the procedure for applying corrections by rolling update. An example of two-node 1:1 standby configuration is used for this explanation.

Flow of operation

Procedure

1. Shut down the standby node (node1).

   To apply corrections to the standby node (node1), shut down the node after stopping RMS.

   Note that, as a result of this shutdown, a cutoff state transition occurs and dual instance operation is disabled until standby restoration is performed.

2. Boot the standby node (node1) in single-user mode.

   Boot in single-user mode.

3. Apply corrections.

   Apply the necessary corrections.

4. Reboot the standby node (node1).

   Reboot the node.

5. Execute standby restoration for the standby node (node1).

   Since the shutdown node (node1) to which corrections have been applied is cut off from the cluster system, execute standby restoration for the node.

6. Execute failover of the cluster application.

   To apply corrections to the operating node (node0), switch the cluster application with the hvswitch(1M) command.

7. Shut down the operating node (node0).

   After the completion of failover, stop RMS, and then shut down the node.

8. Boot the operating node (node0) in single-user mode.

   Boot the node in single-user mode.

9. Apply corrections.

   Apply the necessary corrections.

10. Reboot the operating node (node0).

    Reboot the node to apply the corrections to the system.

11. Execute standby restoration for the operating node.

    Since the shut-down node (node0) to which corrections were applied is cut off from the cluster system, execute standby restoration for the node.

12. Execute failback.

    Restore the state of the standby layout defined at installation by executing failback operation, as required.

• For details on the corrections, refer to the manuals provided with the corrections.
• For details on standby restoration of cluster applications, see "Starting a Cluster Application." For details on failback, see "Switching a Cluster Application."
