Drives Disappear After SCSI Reset
Right now I have two disks and one CD-ROM drive in my Alpha 433au (all
attached to the internal ribbon cable). The SRM recognises them correctly
thus:
dka0.0.0.1009.0 DKA0 COMPAQ ST32550W 6415
dka400.4.0.1009.0 DKA400 MATSHITA CD-ROM CR-508 XS03
dka600.6.0.1009.0 DKA600 IBM-PSG DDYS-T18350N M S96E
However, when I start the Debian installer (4.0R9), during the boot sequence
it does a SCSI reset and then only recognises the first disk, thus:
scsi(0:0): Resetting SCSI BUS
scsi0 : QLogic QLA1040 PCI to SCSI Host Adapter
Firmware version: 7.65.06, Driver version 3.26
Vendor: COMPAQ Model: ST32550W Rev: 6415
Type: Direct-Access ANSI SCSI revision: 02
So, for whatever reason, the CD-ROM and the other hard disk disappear. I
have checked the termination and it *seems* to be correct in that the disks
and the CD-ROM are not (or *should* not) terminating anything. There is a
terminator at the end of the SCSI cable, and I believe the QLA1040 SCSI
adapter does its own termination:
>>>sh pk*
pka0_host_id 7
pka0_mode ultra
pka0_soft_term diff
I have noticed that if there is a disk with an ID less than that of the
CD-ROM then only that disk is recognised after the reset and the CD-ROM and
higher disks are not. If there are no disks with an ID less than the CD-ROM,
then the CD-ROM and the higher disks are recognised.
Can anyone tell me if there is a way to resolve this?
Thanks
Rob
