Starting GPFS automatically

You can specify whether to start the GPFS daemon automatically on a node when it is started.

Whether or not GPFS automatically starts is determined using the autoload parameter of the mmchconfig command. The default is not to automatically start GPFS on all nodes. You may change this by specifying autoload=yes using the mmchconfig command. This eliminates the need to start GPFS by issuing the mmstartup command when a node is booted.

The autoload parameter can be set the same or differently for each node in the cluster. For example, it may be useful to set autoload=no on a node that is undergoing maintenance since operating system upgrades and other software can often require multiple reboots to be completed.
