.SH "Description"
.PP
Use the \fBmmlsmgr\fR command to display which node is the file system
manager for the file system.
.PP
If you do not provide a \fIDevice\fR operand, file system managers for
all file systems within the current cluster for which a file system manager
has been appointed are displayed.
.SH "Parameters"

.RS +9
The device names of the file systems for which the file system manager
information is displayed. 
.PP
If more than one file system is listed, the names must be delimited by a
space. File system names need not be fully-qualified.
\fBfs0\fR is just as acceptable as \fB/dev/fs0\fR.
.PP
If no file system is specified, information about all file systems is
displayed.

If you are a root user:

1. You may issue the \fBmmlsmgr\fR command from any node in the GPFS
cluster.
.HP 3
2. 
When using the \fBrcp\fR and \fBrsh\fR commands for remote
communication, a properly configured \fB.rhosts\fR 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 either the
\fBmmcrcluster\fR
or the
\fBmmchcluster\fR command, you must
ensure:
.RS +3
.HP 3
a. Proper authorization is granted to all nodes in the GPFS cluster.
.HP 3
b. The nodes in the GPFS cluster can communicate without the use of a
password, and without any extraneous messages.

.HP 3
3. As root, a user can also issue the \fBmmlsmgr\fR on remote file
systems.

.PP
If you are a non-root user, you may specify only file systems that belong
to the same cluster as the node on which the \fBmmlsmgr\fR command was
issued.
.SH "Examples"
.RS +3
.HP 3
1. To display the file system manager node information for all the file
systems, issue this command:
.sp
.nf
mmlsmgr\ 
.fi
.sp
The system displays information similar to:
.sp
.nf
file system      manager node [from 199.114.68.69 (k156gn02)]
---------------- ------------------
fs1              199.114.68.70 (k154gn01)\ 
fs2              199.114.68.71 (k154gn02)\ 
fs3              199.114.68.72 (kolt2g_r1b42)
.fi
.sp
.sp
The output shows the device name of the file system and the file system
manager's node number and name, in parenthesis, as they are recorded in
the GPFS cluster data.
.HP 3
2. To display the file system manager information for file systems
\fBgpfs2\fR and \fBgpfs3\fR, issue this command:
.sp
.nf
mmlsmgr gpfs2 gpfs3
.fi
.sp
The system displays information similar to:
.sp
.nf
file system      manager node [from 199.114.68.69 (k156gn02)]
---------------- ------------------
gpfs2              199.114.68.70 (k154gn02)\
