Requirements for a PowerHA cluster
IBM PowerHA SystemMirror for AIX detects system failures and manages failover to a recovery processor with a minimal loss of user time.- PowerHA failover and failback
If a node fails, the server cluster transfers the groups that were being hosted by the node to other nodes in the cluster. This transfer process is called failover. The reverse process, failback, occurs when the failed node becomes active again and the groups that were failed over to the other nodes are transferred back to the original node. - Installing and configuring PowerHA SystemMirror for AIX
You can configure the Tivoli Storage Manager server for AIX clustered environments by using IBM PowerHA SystemMirror® for AIX. - Installing the Tivoli Storage Manager server on a production node for PowerHA
Install the Tivoli Storage Manager server on a production node for PowerHA to be able to configure the server for clustering. - Installing the Tivoli Storage Manager client on a production node for PowerHA
You only need to install the backup-archive client file set, which contains the backup-archive client files and the administrative command-line client. - Verifying the configuration of the Tivoli Storage Manager server for PowerHA
When you configure the Tivoli Storage Manager server to use PowerHA, you must verify the configuration. - Setting up the standby node for PowerHA
For PowerHA, ensure that the Tivoli Storage Manager server is not running on the production node before you set up the standby node. - Defining the removable media storage devices to AIX for PowerHA
For an AIX operating system, you must define the removable-media storage devices that are used by Tivoli Storage Manager on the production and standby nodes. The library manager validates that the cartridge that contains the removable-media storage device is in the correct drive. - Completing the cluster manager and Tivoli Storage Manager configurations
Update the cluster manager configuration to define the Tivoli Storage Manager server as an application, owned by the production node and a failover resource of the standby node. - Troubleshooting the PowerHA clustered environment
Review the following list for information about troubleshooting common problems. The information that is provided for IBM PowerHA SystemMirror for AIX does not represent all possible scenarios.
