drop cluster

Removes each instance from a cluster and then removes the cluster definition from the cluster configuration file.

The drop cluster command also removes regular files associated with the cluster and the cluster agent plug-ins that manage the cluster. The cluster must be down to use drop cluster.

  • sybcluster prompts for confirmation before dropping the cluster.

  • Due to certain file-system locking, the UAF plug-ins may not be deleted after you use drop cluster. Verify that the $SYBASE_UA/nodes/*/plugins/<cluster_name> directory has been deleted. If the directory still exists, delete it.

  • drop cluster:
    • Removes cluster and instance entries from the interfaces file, configuration files, and specified data devices.

    • Marks the quorum device as unused.
