621. You may issue the \fBmmlsmgr\fR command from any node in the GPFS
63cluster.
64.HP 3
652.
66When using the \fBrcp\fR and \fBrsh\fR commands for remote
67communication, a properly configured \fB.rhosts\fR file must exist
68in the root user's home directory on each node in the GPFS
69cluster. If you have designated the use of a different remote
70communication program on either the
71\fBmmcrcluster\fR
72or the
73\fBmmchcluster\fR command, you must
74ensure:
75.RS +3
76.HP 3
77a. Proper authorization is granted to all nodes in the GPFS cluster.

87If you are a non-root user, you may specify only file systems that belong
88to the same cluster as the node on which the \fBmmlsmgr\fR command was
