To change the running AZ while the instance is running, use the AWS Management Console and perform the following steps.
Set the value of the tag "fujitsu.pclswr.is_recovery_target" of the instance of the cluster node to false.
Stop the instance of the cluster node. Note the integer value and instance ID that identifies the cluster node, which is the value of the cluster node instance tag "fujitsu.pclswr.id".
Terminate the instance that you stopped in step 2.
Create an instance in the AZ to be modified according to "A.2.3.1 Creating Cluster Node Instance" from the AMI tied to the instance of the cluster node. At this time, set the value of the cluster node instance tag "fujitsu.pclswr.id" to an integer value that identifies the cluster node in Step 2. Also note the instance ID of the instance you created.
Add the instance you created to the ELB's target group.
Change the instance ID of the CloudWatch alarm from the instance ID in Step 2 to the instance ID in Step 4. Determine what to change by the integer value that identifies the cluster node at the end of the alarm name. For more information about alarm names, see "A.2.4.3 Configuring CloudWatch Alarm".
Modify the items of a eligible instance registered to the table "Fujitsu-Pclswr-DB-Switcher" in Amazon DynamoDB. The items to be modified are checked from the items "SystemID" and "InstanceID". Change the value of the item "InstanceID" from the instance ID in step 2 to the instance ID in step 4. For more information about the items, see "A.2.4.4 Configuring Amazon DynamoDB".
Verify that the tag "fujitsu.pclswr.is_recovery_target" for the instance you created in step 4 has a value of true.
