Hi, apologies beforehand for the crosspost...
I have a UDB I am using for storage. I am using the NCR810 driver,
assigned to SCSI id 7. The device has been working properly with
the given configuration:
id 0 - IBM DCAS-34330 (4.3GB HDD)
id 1 - Seagate STT8000N (8GB Travan-4 Tape)
id 2 - Plextor PX-R412C (4x24 CD-R)
id 3 - Seagate Medalist ST39140N (9 GB HDD)
I recently acquired some new hardware
id 4 - Seagate ST4340... (~4GB? HDD)
id 5 - Seagate ST4340... (~4GB? HDD)
id 6 - Seagate ST410800N (~8GB HDD)
The ARC BIOS is able to identify all 6 devices, and MILO is also
able to detect all six. However, after the initial probe, the
system hangs. It will go through the entire "Detected scsi disk sdx
at scsi0, channel 0, id x, lun 0" list, but will stop just before
the summary printout where it states "ncr53c810-0-<0,*>: FAST-10
SCSI 10.0 MB/s (100 ns, offset 8)" etc.
I have removed ids 4 and 5 from the bus and the system will boot
with id 6 alone. It will not boot with ids 5 and 6 attached; I did
not try ids 4 and 6, nor 4 and 5 alone.
Does anyone have any ideas of what may be going on? Are there any
known problems with having a full bus? The new hard drives came out
of existing UDB systems where they worked well (two in one system,
one in the other) so I can only assume that the drives themselves
are working.
The SCSI chain is physically:
UDB (adaptor - id7)
3ft external HD50 cable to external CD-R (id2)
6ft external HD50 cable to secondary case
secondary case to ribbon cable
cable:
IBM HDD (id0, TERM)
Seagate Tape (id1)
Seagate HDD (id3)
(new stuff:)
Seagate HDD (id6)
Seagate HDD (id5)
Seagate HDD (id4)
Thanks for any help!
Chris
