Changing the Assure MIMIX for AIX configuration - assure_mimix - 6.0

Use the Assure MIMIX for AIX portal application’s Change Replication Group wizard to change the Assure MIMIX for AIX Replication Group configuration. To add additional logical volumes to be protected, the Resource Groups that are associated with the Assure MIMIX for AIX Replication Group must be online so that the new logical volumes can be discovered. Similarly, to add additional containers, the logical volumes containing the containers must be online and accessible.

Refer to Change a replication groups configuration for more information.

Note that if the Replication Group is active, the following warning message is displayed in the Servers panel:

Replication group is currently active. Configuration changes cannot be saved until the replication group is stopped.

You will be allowed to continue through the Change Replication Group wizard and make changes, until the Summary panel is displayed, after which the following warning message will be displayed:

Replication group is currently active. Configuration changes cannot be saved until the replication group is stopped. Go to the Replication Groups portlet in the Assure UI portal and stop the replication group. After the replication group is stopped, return to this wizard and click Finish to save your configuration.

At this time, the Replication Group must be stopped so that the configuration changes can be deployed to the production and recovery servers. Please do not click the Finish button or use the Assure UI portal to stop the Replication Group. Use PowerHA to take the Resource Group offline, as described below:

1. Use PowerHA to bring Resource Group APPLICATION_RG offline. Wait for the Resource Group to be offline before proceeding to the next step.

2. On the recovery server execute the following command to stop the Replication Group:

   rtstop -FC <Primary ContextID>

   For example:

   rtstop -FC1

3. Return to the Summary panel of the Assure UI portal and click the Finish button when the following message displayed:

   The following is a summary of this replication group's configuration. To save and initialize this configuration on the specified servers, click Finish. To cancel, click Cancel.

4. After the configuration changes have completed, execute the following command to start the Replication Group on the recovery server:

   rtstart -C <Primary ContextID>

   For example:

   rtstart -C1

5. On the production server, use PowerHA to bring Resource Group APPLICATION_RG online.
