Enabling CCR

Cluster configuration repository (CCR) is the cluster configuration method used in the IBM Storage Scale cluster. It is enabled by default on the cluster. If CCR is not enabled on the cluster, you can run the mmchcluster --ccr-enable command to enable it.

Note: Cluster configuration using primary and secondary server is deprecated and has been removed.

In IBM Storage Scale, unless CCR is enabled on the cluster, you cannot run the mmchconfig release=LATEST command to change the minimum release level to the latest version.
