The mmdiag command

The mmdiag command displays diagnostic information about the internal GPFS state on the current node.

Use the mmdiag command to query various aspects of the GPFS internal state for troubleshooting and tuning purposes. The mmdiag command displays information about the state of GPFS on the node where it is executed. The command obtains the required information by querying the GPFS daemon process (mmfsd), and thus, functions only when the GPFS daemon is running.
