A quick note, I did a similar thing w/scsi IDs on my alpha 200 4/166. I had
the internal NCR adapter set to initiate on SCSI id 6, and I added an
adaptec 2940UW to initiate on SCSI id 7. Then I chained the system disk,
the ncr and the adaptec together, and taught the kernel only about the aha.
This way I could boot off of the ncr via the SRM, and use the faster (ultra)
mode of the aha when I was booted. Pretty nifty for a one card hack, I
Maybe not relevant, but that's my $0.02.
And a second question: a year or two ago, I was working at a place where
they had bunches of Sequent machines. These machines could share disk packs
connected only via scsi - no proprietary busses AFAIK. Each machine was
able to mount the same volume read/write. What would be involved in doing
this? Is this just a filesystem feature, or is there a more complicated
SCSI locking protocol which takes place?
