Replacing a repository disk with SMIT

Cluster Aware AIX® (CAA) detects when a repository disk failure occurs and generates a notification message. You will continue to receive notification messages until you replace the failed repository disk with a new repository disk.

The cluster operates in a restricted mode until you replace the failed repository disk. You cannot change the cluster configuration or rejoin nodes to the cluster until you replace the failed repository disk.

To replace a repository disk with a new disk, complete the following steps:

  1. From the command line, enter smit sysmirror
  2. From the SMIT interface, select Problem Determination Tools > Replace the Primary Repository Disk, and press Enter.
  3. In the Repository Disk field, press F4 (List) to select an available disk from all nodes in the cluster, or enter the name of the disk if a backup repository disk has not been configured.
    Note: When you first access the Replace the Primary Repository Disk window, the Repository Disk field displays the current repository disk.
  4. Press Enter to set up the selected disk as the new repository disk for the cluster.
  5. After synchronizing the configuration, you can verify that the new repository disk is working by running the /usr/sbin/lscluster -d command.
