scsi support?

[tecknophreak]

I want to turn on scsi tape support in my comp. How do I go about doing this?
RH 7.1

i'm gonna take a wild guess, but there may be a howto on it. (/usr/doc/HOWTO or someplace similar on your system).

also you can try asking google (http://www.google.com/linux?site=search&restrict=linux&hl=en&safe=off&q=scsi+howto)

i think there's a seperate boot img for scsi stuff when you are installing, so it may end up being something you need to compile into the kernel (or set up as a loadable module, whatever). i just don't know enough about it.

[tecknophreak]

Okay, I've narrowed it down to working with the Kernel, one step at a time, but I don't know where the config file is in RH. It's at /usr/src/linux/.config but not in RH. damn bastards

[teeitup]

You are correct. You need to add scsi support to your kernel.
Simply cd to /usr/src/linux/
Choose your tool...
make config
make menuconfig
make xconfig
Go to the scsi section and add what you need. It's your choice if you use modules or not. I always compile scsi into my kernels.
The config program should start with the last saved configuratation. If not take the time and build a true custom kernel for yourself.

I keep an entry in my /etc/lilo.conf for testing new kernels...

image=/usr/src/linux/arch/i386/boot/bzImage
label=Linux-Fresh
read-only
optional

Depending on how you changed the module configuration you'll need to make the modules and install them or not..

Run lilo and reboot. If it doesn't work your original kernel is untouched and you can try again.

Good Luck,

When I did a make modules I got errors -

missing whitespace
parse error,
make[2] dummy.o Error 1
make[1] modsub_dir_net Error 2
make _mod_drivers Error 2

Should I try to fix them myself? HAHA Or what? I got the source off of my RedHat cdrom, so it should be right, right? All I changed was the scsi tape support and adaptec driver

[tecknophreak]

I've added the scsi tape support on my new kernel, but it's doing the same thing it was doing before! :rolleyes:

I can't write correctly to the tape drive. Where can I go to get hardware compatibility, as in a list, not the HOWTO?

Where can I go to get hardware compatibility

If you are using Redhat, then I would try RH's site for the HCL.

Does the SCSI or Ftape how-to not have what you need?

[tecknophreak]

Well the Redhat hardware only lists one or two dell tape drives, that I can see. The SCSI-HOWTO helped me configure the tape support into my new kernel, but that's all. I want to be able to use the st and mt ioctl commands along with the read/write commands.

A while ago when I was looking for either a ethernet or modem card I found a really good hardware site, just can't find it anymore

[gwhitney]

This probably won't help but I tried something similar. I was trying to add a Dell SCSI RAID array to RH 7.1. Couldn't do it. No drivers for 7.1 and the kernel wasn't seeing the hardware properly. Plus Dell doesn't support 7.1 yet. 7.1 found it but wouldn't talk to it.

I loaded 7.0 and everything works like a charm upon install.

Redhat's on-line knowledge base is pretty ridiculous.

can somebody have an idea for this problem also ...

resource:
OS -> RedHat 6.2
Tape -> HP Surestore DDS3 DAT tape drive
SCSI -> INITIO(W) SCSI

what has been done:
recompiled the kernel with SCSI support and INITIO(W) driver.

situation:
mt -f /dev/st0 status (or) rewind is still cannot execute due still havn't seen the tape drive in dmesg yet !!

i will be very much appreciate if anyone assists my problem...

^-^

According to the Google search (http://www.google.com/linux?site=search&restrict=linux&hl=en&lr=lang_en&safe=off&q=HP+Surestore+DDS3&btnG=Google+Search) that drive is supported.

If you don't like reading manuals and HOWTO's, I predict that your Linux experience will prove to be very frustrating. Good luck.
