[H-GEN] mounting sco hd's under linux

[Tony Melia]

 Normally Compaq and most other SCSI raid controllers have a different drive
geometry than a standard SCSI controller, so the answer is almost definitely
yes - you MUST access them through the original array controller.  You
should be able to access the partitions under linux if you have compiled the
sco filesystem support, so you don't need to boot SCO e.t.c, but in the long
run it may be easier to do that.

Howdy - I have got a couple of mirrored scsi hd's which contain a sco 5.05.
I need to mount them under a different linux box to access files without to
fire up the original box which has become a production linux server. Not a
good thing to take down just to access a bunch of old files for data
recovery purposes.

I can see both (sda,sdb) with sfdisk. There are four partitions/slices
sda(b)1 to sda(b)4. 1,2,4 are empty and 3 contains a 'Compaq diagnostics'
id(12) entry. A mount -t sysv on /dev/sda(b)3 does not mount anything.
It says - VFS: unable to find oldfs superblock on device sd(8,3)/sd(8,19)
respectively and the usual mount: wrong fs type, bad option etc thing.

Both drives used to be connected through a compaq array controller ran in
raid
1 mode. Google has not been too helpful here with very few information only.

Is there a way to mount either (I'd actually need only one I think) or both
of them to access the file system? Do I really have to connect them to the
actual compaq array controller going through a normal sco system boot-up?

Perhaps I should mention kernel 2.4.20 on i686 and the sym53c8xx scsi
driver. 

Cheers

Johannes
