The DR health command is used to get the connection status of one cluster from another cluster in mirroring-enabled clusters. The cephblockpool is queried with mirroring-enabled and If not found will exit with relevant logs. Optionally, args can be passed to be appended to ceph status, for example: --debug-ms 1.
Example: kubectl rook-ceph dr health [ceph status args]
kubectl rook-ceph dr health
