Do you have just part of the RAID set, or enough disks to make a complete one? If the
latter then it's a matter of reverse engineering the RAID layout, which is likely to
be doable.

Oops. I guess the fingers work as good as the memory. Sorry
about that. I've got about 20 of them. I know they haven't
been used since they were taken out of the VAX Cluster I ran
at the University. Nothing I have used the SB boxes with since
then would know what to do with 9GB of disk space. :-)
But, if needed I could probably test them on a PC I have with
an Adaptec SCSI in it. It's intended for Ersatz-11 but I expect
does could use a disk that big. Too bad there's no way to read
them. Might be some interesting stuff left behind by the VAX.
Why is there no way to read them? If you have a PC with a SCSI card you can easily boot
into the Linux or BSD distro of your choice and make a dd (or ddrescue) image of the
entire drive, which could then be accessed by whatever means.
These disks were part of a really large RAID array in a SAN connected to
the VAX cluster. There is no way of reconstructing it and so no way to
extract usable information.
