I've got a problem with a new DN3500 with the 690MB disk ...
if I shut down the node, I can't salvage the disk. If I
boot the machine diskless off of another node, I can bring up
AEGIS and then run SALVOL, but the stand-alone version of
SALVOL just hangs (whether the machine is booted off of its
own disk or it's booted diskless). If I boot the machine
off of another node, I am able to run the winchester disk
diagnostic under DEX (using the default settings) with no
problems. If I try to run DEX off of the DN3500's disk, the
winchester diagnostic will not execute (I get a message about
a bad PV label (?)), but the other diagnostics (CPU, FPU, MEM,
RING) all seem to run OK.

If I bring the machine up as a diskless machine, salvage the
disk, shut it down again, and boot it off of it's own disk it
seems to be fine. I get no disk errors, I can run SAX -CIT,
I can do a backup  -- no problems -- but if I then shut the
machine down again and try running salvol, it hangs again.

I've checked the SR9.7 and SR9.7.1 release notes, and I don't
see anything about bugs in either salvol or the winchester
diagnostics for DEX. I've called this in as a possible 
hardware problem, but I'm not really certain that there is
anything wrong with the disk. Does anyone have any knowledge
of problems with salvol/DEX and the 690MB disks?
