Hello out there,

today two new SCSI-disks and the HP-SCSI-EISA-Interface card arrived!
:)

First step. I installed the EISA-card as described in the manual to
the second slot in the HP9000/750.
After the reboot the eisa_config script was executed automatically.
The new interface-card was detected correctly.

Second step. The special files were made. 

Third step. I tried /etc/diskinfo to check the system.

Failure! :(

Then I read the manuals and checked cabling etc. nothing.
I checked that

the cable can be used with SCSI-2,

the terminator can be used with SCSI-2

the special files are made right for the EISA-Slot 2

Then I found the following messages with /etc/dmesg:

SCSI: sense key, lun 0, target 6, bus 0: Unit Attention
SCSI: sense code, lun 0, target 6, bus 0: Power On or Reset or Bus Device Reset
SCSI: Status bytes, lun 0, target 6, bus 0:
		70 0 6 0 0 0 0 a 0 0 0 0 29 0 0 0 0 0
SCSI: lun 0, target 6, bus 0, ASC 29, ASCQ 0, sense key 6, ASL a,
	   sense key specific bytes: 0 0 0

[...]

s0_timeout: sc = 0x42, tgt_id = 0x0
s0_timeout: sc = 0x42, tgt_id = 0x1
s0_timeout: sc = 0x42, tgt_id = 0x2
s0_timeout: sc = 0x42, tgt_id = 0x3
s0_timeout: sc = 0x42, tgt_id = 0x4
s0_timeout: sc = 0x42, tgt_id = 0x5
s0_timeout: sc = 0x42, tgt_id = 0x6


What does that mean. The s0_timeout-messages appear when I execute the
/etc/diskinfo command.
What is the meaning of the SCSI:...-messages?

My special interest is to know is the EISA-card installed in the right
way, are the special files ok, or is the problem caused by the
disks. They are not HP-Products. They are DEC-SCSI-disks (SCSI1!). In
the case with the SCSI-2 connectors is a small SCSI-1 <> SCSI-2 trans-
former. Could it be the troubles cause. The disks work properly with
SCSI-1 interfaces at our HP9000/710.
