Hi all,
Perhaps someone could help me with a problem I have. I cannot seem to
configure the AIC7xxx driver to work in Ultra SCSI mode. I have several
disks in the systm, one of which is Ultra SCSI (the Quantum fireball):
[root@macpress /root]# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: QUANTUM Model: LPS525S Rev: 3110
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: CONNER Model: CFA540S Rev: 13B0
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 03 Lun: 00
Vendor: QUANTUM Model: LPS525S Rev: 3110
Type: Direct-Access ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: QUANTUM Model: FIREBALL_TM3200S Rev: 300X
Type: Direct-Access ANSI SCSI revision: 02
The driver tells me it is not in Ultra SCSI mode:
[root@macpress /root]# cat /proc/scsi/aic7xxx/0
Adaptec AIC7xxx driver version: 4.0/3.2/4.0
Compile Options:
AIC7XXX_RESET_DELAY : 15
AIC7XXX_TWIN_SUPPORT : Enabled
AIC7XXX_TAGGED_QUEUEING: Disabled
AIC7XXX_PAGE_ENABLE : Disabled
AIC7XXX_PROC_STATS : Disabled
Adapter Configuration:
SCSI Adapter: AHA-2940A Ultra
(AIC-785x chipset)
Host Bus: Single
Base IO: 0x6000
IRQ: 12
SCBs: Used 3, HW 3, Page 3
Interrupts: 3181041
Serial EEPROM: True
Extended Translation: Enabled
SCSI Bus Reset: Enabled
Ultra SCSI: Disabled
Target Disconnect: Disabled
I have enabled Ultra SCSI in the BIOS setup page for the Adaptec card, for
both the controller and SCSI id 6 (the fireball).
I am running RedHat 4.2, using the initrd option to load the driver (?I
don't completely understand this?), and I have a lilo boot block on my IDE
drive to boot linux:
[root@macpress /root]# cat /etc/lilo.conf
boot=/dev/hda6
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
image=/boot/vmlinuz
label=linux
root=/dev/sdd1
initrd=/boot/initrd
read-only
image=/boot/vmlinuz.orig
label=orig
root=/dev/sdd1
initrd=/boot/initrd.orig
read-only
image=/boot/vmlinuz.orig
label=recover
root=/dev/hda6
initrd=/boot/initrd.orig
read-only
image=/boot/vmlinuz.test
label=test
root=/dev/sdd1
initrd=/boot/initrd.orig
read-only
I have built a new initrd image, the configuration file is I believe:
[root@macpress /root]# cat /etc/conf.modules
alias scsi_hostadapter aic7xxx
options aic7xxx ultra
alias eth0 ne
options ne io=0x340 irq=10
I have also tried passing the aic7xxx=ultra option to LILO at boot time,
but to no avail. I have also tried setting all my SCSI devices in the
Adaptec BIOS page to Ultra mode, but this makes no difference.
Using hdparm -Tt I test my fast drive, and it is only marginally faster
than my existing SCSI drives, and actually significatly slower than my IDE
drive, so it seems clear that Ultra SCSI is not enabled.
Kernel version:
[root@macpress /root]# cat /proc/version
Linux version 2.0.30 (root@macpress.demon.co.uk) (gcc version 2.7.2.1) #2
