Problem Summary: Transitioning to the single-user runtime level from the multiuser level is not supported.
If this command is issued under certain configurations, shutdown of the node might hang, preventing evacuation (switchover) of services on that node.
Workaround: On the node where the shutdown is hanging, use either halt(1M) or reboot(1M) to force the node to shut down.
To prevent the hang from occurring, avoid executing any of the following commands for shutting down a cluster node:
init S
init s
init 1
init 2
shutdown [without -i flag]
Instead, use one of the following commands:
To take a node down to firmware:
shutdown -i 0 or init 0
To take a node down and power off:
shutdown -i 5 or init 5
To reboot a node:
shutdown -i 6 or init 6
To shut down all cluster nodes to firmware, execute this command on one node:
cluster shutdown
