: The following message is a courtesy copy of an article
: that has been posted as well.
:
: I have a 256mb Sparc 20 with the following configuration:
:       4 SCSI cards
:             1 internal
:             1 on Ethernet Card
:             2 Single-Ended Wide Differential
:
: Off the internal controller, I have 2 internal and 2 external
: disks.  I do not have any disks off of the ethernet card.
: On the two diffs, I have 3 drives and 4 drives.  The problem
: I am having is that the computer only recognized one set
: of disks off of the diffs.  I have swapped the drives, and
: either comes up, also if only one card is in the machine, it
: works find.
:
: If I perform a probe-scsi-all at the boot prompt, again I see
: all controllers, but I only see the disks off the internal and
: one of the single ended controllers.  Am I hitting some type
: of bios restriction?  Has anyone run into this problem before?
:
: All help is appreciated.

Lets see if this works for ya:

make SURE to check the termination on those drives.
Sometimes you need to pull resistors or set some jumper.
(just for kix, try to stay between 0 & 7 on the SCSI ids.)

do a boot -r from the command-line.

Solaris seems to want that in order to create the new devices to
access the disks.
