[parisc-linux] Question about RAID array

[Bjørn Djupvik]

Hi, I am considering migrating a few boxes from hp-ux to parisc-linux as I
have done this successfully on a 712/100 already.. The boxes in question
are D-class servers (220,230,250,etc) and some of them have jurassic-era
(ancient) C2300 disk arrays attached to them, which I know very little
about. Can anyone confirm that this is going to work under parisc-linux,
I'd like to see a "success story" before I rip out hpux and install Linux
=)

1) D-class is quite a different beast than 712.
   Has anyone tried installing 0.9.3 on a D-class?
   Are all the interface cards you care about supported with linux drivers?

2) can someone confirm C2300 disk array  == "Cascade" from 1991-93?
   If so, it has utilities/daemon running that monitors the health of
   the array. I highly doubt that utility will ever get ported since it
   needs kernel driver support for a non-existant LUN 5 or 7 (I forgot).
   Consider replacing the array with SCSI JBOD. You'd get an order of
   magnitude increase in storage capacity and performance.

yeah - that's a good idea.

I've installed 0.9.3 successfully on a D270.  Just needed the
ncr53c8xx=burst:3 thing.

I can't comment on the disk array thing, though.
