I have an IDE based PC running Linux/CentOS4 to which I wish to
attach a scsi dlt. The host controller is an Adaptec AHA3940
something that lspci reports as:
SCSI storage controller: Initio Corporation 360P (rev 02).
I would like to have the system load the driver for this adapter at
boot but I have two problems: 1. I am not sure which driver to use;
and 2. I do not know how to force Linux to load a driver module.
My research to date indicates that the driver module for this
device likely is one of:
/lib/modules/2.6.9-11.EL/kernel/drivers/scsi/aic7xxx/aic7xxx.ko
/lib/modules/2.6.9-11.EL/kernel/drivers/scsi/aic7xxx/aic79xx.ko
/lib/modules/2.6.9-11.EL/kernel/drivers/scsi/initio.ko
My reading of man modprobe.conf and modprobe lead me to conclude
that the following needs to be added to /etc/modprobe.conf
install <name of one of the above drives>
alias scsi_host_adapter <name used for install>
Can somebody confirm whether I am on the right track or not and
provide some advice has to how to proceed? Which is the preferred
driver for this card? Do I have to make additional entries for the
tape drive itself an HP surestore dlt vs80? How do I create the
necessary /dev/st# and /dev/mt# entries? Is there a Linux utility
program like kudzu that can probe the hardware and automate any of
this?
I am a digest subscriber so replies that only go to the list will
reach me in about 24 hours.
Regards,
Jim

Then run dmesg to see if it reports success. Should see something similar to: SCSI subsystem driver Revision: 1.00 scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36 <Adaptec 3960D Ultra160 SCSI adapter> aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36 <Adaptec 3960D Ultra160 SCSI adapter> aic7899: Ultra160 Wide Channel B, SCSI Id=7, 32/253 SCBs if it is successful. At that point, make your changes to modprobe.conf and you should be fine for reboots. The OS should create the /dev/*st0 files for you. In dmesg you should see something like: st: Version 20040102, bufsize 32768, max init. bufs 4, s/g segs 16 Attached scsi tape st0 at scsi0, channel 0, id 6, lun 0> I am a digest subscriber so replies that only go to the list will > reach me in about 24 hours. >Thanks for noting, I CC'd you directly.

You then want to rebuild your initrd so the SCSI module is loaded at startup. However you are correct in that you want to use: alias scsi_host_adapter aic7xxx I'm guessing it's going to be the aic7xxx anyway. To rebuild your ramdisk you can (At minimum): mkinitrd -f /boot/initrd-`uname -r`.img `uname -r` When you install new kernels this will be done for you automatically. -- Jason

That seems to have worked. What is the precise line to put into /etc/modprobe? Should it go at the start or the end of the file or does it much matter? install initio ??? Regards, Jim
