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
