HP XC System Software Administration Guide Version 3.2

2. Invoke the startsys command with the --image_and_boot option:
# startsys --image_and_boot
3. If your system has been configured for improved availability and the nodes that provide
availability have been reimaged, enter the transfer_to_avail command to transfer
control to the availability tool:
# transfer_to_avail
For additional information on options that affect imaging, see startsys(8).
3.2.4 Restarting a Node for Imaging
The following procedure describes how to image and boot a node that is already running. In this
instance, the node needs to be imaged to accommodate a recent update to the golden image.
1. Log in as superuser (root) on the head node.
2. Invoke the startsys command with the --force and --image_and_boot options:
# startsys --force --image_and_boot node
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 preferred for shutting down the system.
2. This step only applies if your system is configured for improved availability. Otherwise,
proceed to step 3.
If any of the following criteria applies to your system, enter the transfer_from_avail
command:
• You are shutting down the HP XC system with the intention of running the
cluster_config utility.
• You are rebooting the head node and you use the HP Serviceguard Quorum server.
Ignore this step (and proceed to step 3) if any of the following apply:
• You are not rebooting the head node.
• You are rebooting the head node, and you use LOC_LUN under HP Serviceguard.
The format of the transfer_from_avail command is as follows:
# transfer_from_avail
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).
