Security
You must have root authority to run the mmsanrepairfs command.
When using the rcp and rsh commands for remote communication, a properly configured .rhosts file must
exist in the root user’s home directory on each node in the GPFS cluster. If you have designated the use
of a different remote communication program on the mmcrcluster or the mmchcluster command, you
must ensure:
1. Proper authorization is granted to all nodes in the GPFS cluster.
2. The nodes in the GPFS cluster can communicate without the use of a password, and without any
extraneous messages.
