I am having a problem detecting an external scsi drive connected to the
scsi port on the system board of a SPARCstation 20 - Solaris 9 - SunOS
5.9. Also, I can no longer boot the system, even with this external
drive disconnected.
The external drive is a Sun X5237A 18.2GB 10K USCSI in a Sun 611 UniPack
enclosure, with a 68/50 pin cable. I have tried address 0 or 2 with the
same results, described below.
>From the OK prompt, 'test scsi' gives the following:
Dma register test -- succeeded.
Esp register test -- succeeded.
Dma read test -- succeeded.
Dma write test -- succeeded.
With the external drive _disconnected_, if I run probe-scsi-all, I can
see my two internal hard drives and CD-ROM drive:

With the external drive _connected_ and set at address 0, as soon as the
external drive is probed, the screen completely clears, the cursor goes
to the top of the screen, and all I can read is the tail end of the
information from the probe of the external drive:

(screen clears, cursor goes to top of screen)

If I change the address to 2, the screen clears between the information
for Target 1 and Target 3 appearing.

If I do a test-all (with the external drive either connected or
disconnected), the following occurs:
o the memory test passes ok
o floppy drive test passed ok
o font test starts to run, then:
the screen clears, a finely-detailed, colored plaid background
screen appears, then this becomes overlaid about half-way down
with the normal white screen. The first thing I can read is:
-- succeeded.

then one blank line with only the plaid background, then white screen
continues with the following:
Using AUI Ethernet Interface
Lance register test -- succeeded
Internal loopback test -- succeeded
External loopback test -- Lost Carrier (transceiver cable problem?)
send failed.
Using TP Ethernet Interface
Lance register test -- succeeded
Internal loopback test -- succeeded
External loopback test -- Lost Carrier (transceiver cable problem?)
send failed.
Self test failed. Return code = -1

Dma register test -- succeeded.
Esp register test -- succeeded.
Dma read test -- succeeded.
Dma write test -- succeeded.

Now I can not even boot the system from the ok prompt. Normally, I do:
'boot disk1:a'
but get an error that the boot program can not be found.
The external drive is not connected when I try to boot. I have powered
down the system several times, but I am still unable to boot.
Please excuse the length of this message, but I am trying to provide all
the relevant information to diagnose the problem.
Thanks,
Barry
