We have a number of Ricoh IS50 scanners attached to an equal number of
4D/35s, and are having the following problem: on some of the hosts
with scanners, we get (SCSI) disk errors, and the following in the
syslog (this from a host named june):

Dec  3 09:16:35 june unix: sc0,1,0: cmd=0x2A Unexpected info phase 46, state 48.  Resetting SCSI bus
Dec  3 09:16:37 june unix: dks0d1s6 (/usr): retrying request
Dec  3 09:19:55 june unix: sc0,1,0: cmd=0x2A Unexpected info phase 46, state 48.  Resetting SCSI bus
Dec  3 09:19:56 june unix: dks0d1s6 (/usr): retrying request
Dec  3 09:21:11 june unix: sc0,1,0: cmd=0x2A timeout after 30 sec.  Resetting SCSI bus
Dec  3 09:21:12 june unix: dks0d1s6 (/usr): retrying request

If the scanner and cable is moved to another 4D/35, all is well with
both hosts.  We are using the cable SGI told us to (Qualtronix's 8-ft.
SCSI cable part# 018-8019-008), and are terminating the bus.  Any ideas
what the cause could be?

If it is on a 35, and you are sure that the problem doesn't 
follow a particular cable, terminator, or scanner (some
scanners might have different firmware), the most likely
remaining cause is that the termpower fuse on the SCSI
board has been burned.  The fuses are all in a group
down near the audio board on the 30 and 35.
