Setting up the standby node for PowerHA

For PowerHA®, ensure that the IBM Storage Protect server is not running on the production node before you set up the standby node.

Complete the following steps to set up the standby node:

1. On the standby node, open the shared volume group and any IBM Storage Protect file systems.
2. On the standby node, install the IBM Storage Protect product code. For more information, see Installing the IBM Storage Protect server on a production node for PowerHA. If the executable files are installed on shared disk space, you might need to install them on the standby node. IBM Storage Protect device drivers, SMIT panels, and other files must be installed in AIX® system directories.
3. Open the dsmicfgx wizard. Follow the instructions to complete the configuration. Select the check box to indicate that this item is a secondary node in the cluster.
4. Start the server on the standby node. Query the database, recovery log, and storage pool volumes to verify that they are the same as when the server was started on the production node.
5. Install the client on the standby node. If the executable files are installed on shared disk space, you might need to install them on the standby node. IBM Storage Protect SMIT panels and other files must be installed in AIX system directories. Use the AIX RCP command with the -p option to copy the dsm.sys file from the production node to the standby node. If the dsm.sys file is changed on one node, it must be copied to the other node.
