Replacing a repository disk
On the Virtual I/O Server (VIOS) Version 2.2.2.0, you can replace a repository disk by using the VIOS command-line interface.
You can replace the repository disk that is used to store
cluster configuration information thereby increasing cluster resiliency.
The replace operation works on a functional or failed repository disk.
When the repository disk fails, the cluster remains operational. While
the repository disk is in a failed state, all requests for cluster
configuration fail. After you replace the failed disk, the cluster
will be fully functional. As part of the replace operation, the cluster
configuration information is stored on the new repository disk. The
following are the requirements that must be met:
- The new repository disk must be at least the same size as the original disk.
- The VIOS logical partitions in the cluster must be at Version 2.2.2.0, or later.
To replace a repository disk, run the chrepos command. In the following example, the hdisk1 repository
disk is replaced with the hdisk5 repository disk.
chrepos -n -r +hdisk5 -hdisk1
