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:
- From the command line, enter
smit sysmirror
- From the SMIT interface, select , and press
Enter.
- 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.
- Press Enter to set up the selected disk as the new repository disk for the
cluster.
- After synchronizing the configuration, you can verify that the new
repository disk is working by running the /usr/sbin/lscluster -d
command.
