Example Of Output From Df Command Showing Multiple Mounts - IBM RS/6000 SP Problem Determination Manual

For further information on Amd options, refer to the man pages in
/usr/lpp/ssp/public/amd920824upl75.tar.Z. The man pages can be extracted with
the commands:
zcat amd920824upl75.tar.Z | tar -xvf - amd920824upl75/amd/amd.8
zcat amd920824upl75.tar.Z | tar -xvf - amd920824upl75/amq/amq.8
mv amd920824upl75/amd/amd.8 /usr/man/man8
mv amd920824upl75/amq/amq.8 /usr/man/man8

If multiple mounts of the same filesystem have occurred (as in Figure 93),
then try to unmount all the Amd-mounted filesystems. The command

/etc/amd/amd-maps are correctly configured. See Figure 93 as an example
of a map file. Ensure that the map files are the same on all the nodes (use
