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.

I'm not so sure it's an Adaptec controller if it's reporting itself as an Initio, but I suppose I could be wrong.

Chances are it's the initio.ko module.

Yeah, you're pretty well on the right track. Try running
modprobe initio
as root. 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

Thanks for noting, I CC'd you directly.

So. 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 ???

Doesn't matter where, but
alias scsi_hostadapter initio
should do it.

The alias is enough to tell modprobe to load the module, I believe. I don't have any install lines for my scsi modules on a couple different machines. If it doesn't work on reboot, you can always add that in, but I don't think it's necessary.

Thank you for your kind assistance. I have just completed a backup to the dlt and everything went fine. I have added the entry "alias scsi-host-adapter initio" to the /etc/modprobe.conf file and I will test whether this works as expected later this weekend.

If you put the card in, the OS should detect it automatically and do the right thing for you. 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.
