Hi,

today i added a second Adaptec SCSI-HA into my system. Previously I had
an AIC-7890 onboard adapter with the following devices (from
/proc/scsi):

Attached devices:
Host: scsi0 Channel: 00 Id: 02 Lun: 00
Vendor: IBM Model: DCAS-34330 Rev: S65A
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 03 Lun: 00
Vendor: SyQuest Model: SyJet-S Rev: 0095
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 04 Lun: 00
Vendor: HP Model: C4324/C4325 Rev: 1.20
Type: CD-ROM ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: TOSHIBA Model: CD-ROM XM-6401TA Rev: 1009
Type: CD-ROM ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 08 Lun: 00
Vendor: IBM Model: DDRS-34560D Rev: DC1B
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 10 Lun: 00
Vendor: IBM Model: DRVS09D Rev: 00F0
Type: Direct-Access ANSI SCSI revision: 03

Now I added another HA (AHA 2940 narrow) with a scanner (Mustek MFS
6000) on ID 5 hooked into it. /proc/scsi/scsi now reports:

Attached devices:
Host: scsi0 Channel: 00 Id: 02 Lun: 00
Vendor: IBM Model: DCAS-34330 Rev: S65A
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 03 Lun: 00
Vendor: SyQuest Model: SyJet-S Rev: 0095
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 04 Lun: 00
Vendor: HP Model: C4324/C4325 Rev: 1.20
Type: CD-ROM ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: TOSHIBA Model: CD-ROM XM-6401TA Rev: 1009
Type: CD-ROM ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 08 Lun: 00
Vendor: IBM Model: DDRS-34560D Rev: DC1B
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 10 Lun: 00
Vendor: IBM Model: DRVS09D Rev: 00F0
Type: Direct-Access ANSI SCSI revision: 03
Host: scsi1 Channel: 00 Id: 05 Lun: 00
Vendor: IBM Model: DRVS09D Rev: 00F0
Type: Direct-Access ANSI SCSI revision: 03

The last entry is definitely wrong, the HA recognizes the Scanner in his
BIOS-Scan correctly.

In /proc/scsi/aic7xxx/1 the device seems to be recognized correctly:

(scsi1:0:5:0)
Device using Narrow/Async transfers.
Transinfo settings: current(0/0/0/0), goal(0/0/0/0), user(25/15/0/0)
Total transfers 1 (1 reads and 0 writes)
< 2K 2K+ 4K+ 8K+ 16K+ 32K+ 64K+
128K+
Reads: 1 0 0 0 0 0 0
0
Writes: 0 0 0 0 0 0 0
0

There seems definitely to be a flaw either in the aic-driver or in the
scsi-system
