[Info-vax] 'Partitioning' raid controller for VMS on Integrity

[dthi...@gmail.com]

I forgot to mention that you can do the same logical disk partitioning with SCSI on Integrity as well.

I have an rx2600 with a 6402 SCSI RAID controller, and have cut a large 7-drive RAIDset into DKx0, DKx1, and DKx2.
