Mounting SCO unix partition

I need to mount the root partition on a SCO Unix system and I'm using the RedHat rescue disks.  What type of filesystem does SCO use?  And assuming the system has 1 scsi harddrive will the root partition be /dev/sda1?
The mount commmand:
mount /dev/sda1 /mnt/disk
yeilds a error saying the system (linux) cannot determine if that partition is a block device, so I assume I must use the -t flag to fill in the filesystem, but that is unknown.  Please help.  Thanks.

SCO uses something called HTFS (I think).

In any case, you need a kernel with the optional support for "System V and Coherent filesystem support" compiled in, for it to support SCO partitions.

Close, but no cigar...

First of all, don't try Linux for that. SCO offers to
build a set of emergency disks for you (type "mkdev fd" and follow instructions).  Older SCO OpenServer versions (up to and including 3) need system specific emergency disks, younger ones (5 and up) can generate generic or specific emergency disks.

If you have OpenServer 5, forget Linux. HTFS (or DTFS, AFS or EAFS, for that matter) are not supported by Linux. Period. Only if you (or someone) installed OpenServer on S51K filesystems (which no one in their right minds does nowadays, no offense meant), you might get lucky, but I still doubt it. Why, you ask? OpenServer subdivides partitions not by using logical partitions in an extended partition, but by having "divisions" (created by divvy) in a "normal" primary partition. I don't think Linux knows this concept. Somewhere hidden in the kernel config is support for BSD slices which is a similar concept, but I don't think you'll get Linux mount to fly on SCO divisions. Sad, but true...

If you have UnixWare, you might stand a chance, but as I don't know that OS very good, I'm afraid I can't help you there.
Fair enough, that's certainly the way to do it, using SCO - although I thought that could create/cope with generic startup disks.

I was assuming that the support in Linux (it actually says SCO!) would cope with the partitions created by fdisk/divvy, but there
you go :)

If all else fails, you can break into a shell from the SCO
Openserver 5 setup floppies, but I can't remember how.

I don't know Unixware either.
