Initialization of the GPFS daemon

GPFS daemon initialization can be done automatically as part of the node startup sequence, or manually by using the mmstartup command.

The daemon startup process loads the necessary kernel extensions, if they are not previously loaded by another process. The daemon then waits for the cluster manager to declare that a quorum exists. When quorum is achieved, the cluster manager changes the state of the group from initializing to active. You can see the transition to active state when the mmfsd ready message appears in the GPFS log file (/var/adm/ras/mmfs.log.latest) or by running the mmgetstate command. When this state changes from initializing to active, the daemon is ready to accept mount requests.
