3.3 Shutting Down the HP XC System
The stopsys command implements the actions to be taken to shut down the system.
The following procedure describes the steps necessary to shut down the HP XC system:
1. Log in to any node as superuser.
Logging in to the head node is the preferred node for shutting down the system.
2. If your system has been configured for improved availability, and you are shutting down the HP XC
system with the intention of reimaging it, enter the transfer_from_avail command:
# transfer_from_avail
If you are shutting down the system without reimaging it, ignore this step.
Chapter 10 (page 129) describes imaging.
3. Enter the stopsys command to shut down the HP XC system. If necessary, you can specify a delay
(in minutes) with the --delay option:
# stopsys --delay 5
Notes:
Use the --full option to shut down the head node. By default, the stopsys command keeps the head
node running.
The stopsys command initiates a shutdown command on the nodes and starts a countdown. The
stopsys command forces the node to power off if it does not power off after the countdown. You can
use the --hard option to ignore the countdown and power the nodes off immediately.
For additional information about the stopsys command, see stopsys(8).
3.4 Shutting Down One or More Nodes
You can shut down only certain nodes by specifying them in a nodelist parameter.
The following example shuts down nodes n2, n3, and n5 gracefully; the nodes are shut down then powered
off:
# stopsys n[2-3,5]
The following example shuts down nodes n1 and n4 by powering them off immediately:
# stopsys --hard n[1,4]
For more information about the stopsys command, see stopsys(8).
3.5 Determining a Node's Power Status
You can determine a node's power status by using the shownode status command and specifying the
node by its node name:
# shownode status n2
ON
Valid power states are ON, OFF, or FAILED.
Specifying more than one node lists the node name and the status, as shown here:
