Hello,
In my experience, this problem is often due to "/tmp" being 100% full.

It appears GPFS 4.1.1 now displays a meaningful message in such a case:
  # df -h /tmp | grep %
                        985M  985M     0 100% /tmp
  # /usr/lpp/mmfs/bin/mmgetstate
  mmgetstate: Unable to obtain the OS name.  The tmp file system may be 
full.
