Cluster management (svc_cluster_management)

This service script enables service providers to attach, detach, and view status of each appliance in a cluster. If an appliance in a

two appliance cluster fails, or can no longer communicate with the other appliance, the remaining appliance becomes

unmanageable.

You can request your service provider to detach the failed appliance from the cluster, and restore the ability to manage the

remaining appliance. Once the issue with the appliance is resolved, you can then use the prep-attach and attach commands to

reattach the appliance back into the cluster.
