How can I find information about the version of GPFS running on a cluster?

Our institution uses IBM’s GPFS for the file systems on all of our clusters. Is there a command, or set of commands, that will provide version (and other) information about each GPFS installation?

IBM answers these questions very well on its website. Here I offer two commands, and provide the appropriate IBM website links.

On Linux:

To display the GPFS version, type:

$ rpm -qa | grep gpfs

To list GPFS configuration information for the cluster, type:

$ mmlscluster
