What I was thinking...
Which reminds me of a comment I saw somewhere
about the possibility of
having a SCSI bus with more than one host adapter on it. Is that even
possible?
Absolutely, as long as the two (or more) host adapters have different
addresses. There are some computer systems that share disk units in
that manner. Of course, the driver software on all hosts needs to be
aware of the need. AFAIK, one can even talk controller-to-
controller. The problem with multiple controllers arises when
low-end or spottily
implemented driver software is used.
I guess that depends on what platform we're talking too. I really hate the
idea of having to just go out and snag a driver off the 'net for something
and hope it works (the usual windoze approach?) but with linux being one of
the platforms in question the source is right at hand.
For example, it's the rare cheap SCSI card that
will respond to an
IDENTIFY--
That a software or hardware issue? (It's been a *really* long time since I've
looked at the details of that stuff.)
or even allow one to change the host address.
I don't think I've had too much of a problem with that, but then most of what
I have on hand here is Adaptec stuff, some of it ISA, some PCI. And then
as I mentioned in that other post, there's the SASI port on the BIgboard II,
which at this point is nothing at all, but seems to offer some nontrivial
potential...
Let's see ya do that with IDE/ATA!
:-)
The only reason I use as much of that stuff as I do is because I keep getting
it basically for free. And it's handy. But I am accumulating a pile of
SCSI stuff too. Including a whole mess of 2G drives -- anybody have a need
for those?
