SUPPORT Adaptec AIC 7880 PCI & Symbios Logic 8751SP SCSI host card

Post by root » Sun, 31 Dec 1899 09:00:00



Hi Folks

Sorry for the lengthy note , I did try a few things but no luck hence I
looking for yor help?

I am trying to get additional SCSI devices on the Symbios PCI SCSI  host
adaptor but unable to see/probe any devices.   I installed linux on the
onboard AIC 7880 PCI ultra-wide scsi disk but installed the additional
Symbios Logica PCI-SCSI interface host adaptor after  the linux install.

Linux  finds the scsi devices on the AIC 7880 host adaptor:

Dec 25 09:53:39 europa kernel: scsi0 : Adaptec AHA274x/284x/294x

The Symbios Logic SCSI Host adaptor is a 100/100BT + PCI Ultra Wide SCSI
combo-card.  The network interface is functioning fine using the PCnet32
driver.

Dec 25 09:53:39 europa kernel: pcnet32.c: PCI bios is present, checking
for devices...
Dec 25 09:53:39 europa kernel: Found PCnet/PCI at 0x7ce0, irq 18.

83 02 c3 cb assigned IRQ 18.
Dec 25 09:53:39 europa kernel: pcnet32.c:v1.23 6.7.1999

My /etc/conf.modules looks like this
alias scsi_hostadapter aic7xxx
alias eth0 pcnet32
alias scsi_hostadapter1 ncr53c8xx

 and "modprobe -c" shows the second host adaptor is loaded?

My system is a HP XU PII/450 and I received the Symbios Adaptor after a
week as it was not included
in the original box. These two adaptors are standard  on top of the IDE
for the CDROM etc.

During install ,linux loaded the SMP kernel as this box can take
another CPU.
Dec 25 09:53:38 europa kernel: Linux version 2.2.12-20smp

When I boot NT I am able to use both SCSI adaptors ( And SCSI disk
attached on Symbios ) and network interface . Lilo is my main boot prg
and is setup for NT and linux

boot=/dev/sda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
default=linux

image=/boot/vmlinuz-2.2.12-20smp
        label=linux
        initrd=/boot/initrd-2.2.12-20smp.img
        read-only
        root=/dev/sda5

image=/boot/vmlinuz-2.2.12-20
        label=linux-up
        initrd=/boot/initrd-2.2.12-20.img
        read-only
        root=/dev/sda5

other=/dev/sda1
        label=dos
I also checked on HP's Linux support site and my system checks out for
linux 6.1
http://hp-linux.cern.ch/support/KayakXUN.php3

Is there any utility under linux to , probe the host adaptors beside
"modprobe".  I also checked the /dev directory and only /dev/sd[a-p] is
available and the boot disk is in /dev/sda[1-nn]
Will linux create new device files? If the second adaptor is present (
How do I verify if it did ?, I expected
another set of /dev/s???[a-p] to be created ? Am I right to assume this
?)

I also read on
http://redhat.google.com/search?q=cache:hp-linux.cern.ch/SupportTable...

 that linux 2.0.36 is workaround to get both 100BT & Symbios working
concurrently, but is not required on 2.1.12? Or is this not the case? I
am a novic on linux

Any pointers or help would be appreciated ?.

regards
dl

 
 
 

1. Support for Adaptec AIC 7880/7890 SCSI host adapter

Folks,

  Does Linux support these adapters?  I tried the RedHat 5.1
  installation without supplying any parameters and it didn't seem to
  work.
