[ILUG] Multiple SCSI host adapters

[ILUG] Multiple SCSI host adapters

[I'm going to play with this later when I go home,
but I'd like to hear other people's ideas before
I go blowing stuff up...]

In general, how well do SCSI disks (and SCSI stuff 
overall) like having two host adapters on a bus?

Specifically, I've got a VAX with a dead ethernet port
and working built-in SCSI.  I've got a Linux box with
a SCSI adapter.  And I've got a SCSI disk (RZ55, big,
noisy, 350MB brute).

Will I be able to (e.g.) dd a kernel image to the
disk and then boot the VAX from it?  Will the disk
get awfully confused with multiple host adapters?
(I don't expect so, but you never know...).

Don't worry about file system integrity and co-ordinating
writes between the two machines.  That's a problem for
another project...  Hmmm, LINUXclusters :-)

Later,
Kenn
