IJ28161: MMCHFS -W FAILS TO CHANGE THE DEVICE NAME.

APAR status

• Closed as program error.

Error description

• Changing the file system name via
  mmchfs -W option does not work if the
  file system manager is on another
  node that is not a Linux node.
  This is due to the new device name
  not being created in /dev at the
  time the daemon open the file system
  with the new device name.
  

Local fix

• Ensure the next file system appointment
  is on a Linux node.  This can be done
  by rearranging the list of quorum nodes.
  If there are no Linux nodes
  in the cluster, run the mmchfs command
  on the file system manager node.
  

Problem summary

• Changing the file system name via
  mmchfs -W option does not work if the
  file system manager is on another
  node that is not a Linux node.
