Locally-mounted File Systems (LMFS) under HP-UX 8.0 are globally visible
throughout the cluster. The degree of heterogeneity of the cluster matters
not; if the configuration is supported, it works. CDFs are no problem, and
work the expected way.

There are limitations in how you can mount filesystems; you cannot mount a
disk from one client onto a mountpoint on another client; that is, once the
mount tree descends into a given client, that client must be able to handle
the rest of the path (notwithstanding symlinks, of course).

HP-IB disks on the 700 are not known not to work. Classic HP doublespeak, I
know. In other words, we haven't yet found troubles, but we didn't
exhaustively test it, and we won't support it, and we're uncomfortable
saying "it should work". Be advised that performance will not be as good as
for the SCSI drives even accounting for raw disk performance differences,
since we didn't optimize for them.

I don't know if the same can be said about the HP-IB DAT drive, though.

Best of luck to you; hope you like the system!
