Thanks for all the replies. Turns out I missed a recent summary pointing out
the problems with Seagate Barracuda discs with Firmware Revision below 17.
(from Mr T. Crummey <tom@sos.bangor.ac.uk>). This will hopefully fix my disk
problem. If anyone missed that summary, and would like a copy, I'd be pleased to
send it on.
The Solaris 2.3 CD labelled "Hardware 5/94" contains more up-to-date patches
than my original (unlabelled) Solaris 2.3 CD.
No-one seems to know much about the Hitachi CDR-3750. I checked the CDROM FAQ,
which mentioned a CDR-1750. Anyway I'm trying a more explicit mailshot on this
problem.
Thanks to...

Original query:
Hello All!
I have just attempted (and failed) to install a headless SS20 PCNFS server
with Sol 2.3 using an internal ST31200W Sun 1Gbyte disk, internal CDROM, and 3
x ST151505 4Gbyte (Seagate Barracuda) external disks (3rd party).
I hit intermittant SCSI errors on power up, which I rationalised as being
caused by the ST15150N disks having different spin-up timer settings which were
quite long, and I didn't allow for. I got thro' the install with a few more
SCSI hiccuphs, but all seemed well. I had by this time formatted the 4Gbyte
disks each as 2 x 2Gbyte partitions. I even managed to
boot off the internal disk.
But subsequently I started to get a variety of SCSI errors for all the
disks, including the internal one. ("timeouts, "data transfer overrun", "data
ovr", "Cmd dump" etc). These are now causing the system to hang when I try to
do anything, even when the big disks are not directly involved.
"probe-scsi" always seems to work OK, correctly reporting the make/model of the big disks.
I ran install off CDROM from a Solaris2.3 CD, but noticed afterwards that the
SS2 had come with a CD labelled "Hardware 5/94". Is this significant?
SCSI-2 cable run to the external disks is 2metres.
I also have a (Sun) FSBE card in the SS20 - is this a legal config? It seems OK
with "probe-scsi-all", which correctly reports the 3 x HITACHI CDR-3750 drives
which are attached. However, with these connected, I get complaints about
illegal block size of 2048. I think there's a dip switch I can change on these
drives to fix this. can anyone help here?
NB the CD drives were not attached when the prior SCSI problems were
encountered!
Any help much appreciated. I will summarise.
