When a scalable partition is powered on, you can use the IBM Director
Console to shut down and power off the scalable partition.
IBM Director notifies the operating system that the scalable partition
will be shut down and powered off in one of the following ways:
- If the device driver for the service processor on the primary scalable
node is available, the operating system attempts to exit from running applications
before it shuts down. Then, IBM Director powers off the servers that are represented
as scalable nodes.
- If the device driver for the service processor on the primary scalable
node is not available, the scalable partition is immediately powered off and
there is no attempt to exit from running applications. In this case, the operating
system can display only a message that it is shutting down. It then flushes
its disk caches before the servers that are represented as scalable nodes
in the scalable partition are physically powered off. Application processes
running on the system are not shut down.
Complete the following steps to shut down the operating system and
power off all servers that are represented as scalable nodes:
- From IBM Director Console, in the Group Contents pane, expand the
tree structure for the scalable system that contains the scalable partition.
- Right-click the active scalable partition that you want to power
off; then, click Shutdown and Power Off.
- Click Execute Now.
