View Full Version : scsi pci card not working

Hi, i'm running the latest version of fedora on a brand new dell optiplex 755 (core 2 quad processor)

I'm having trouble getting my adaptec aha-2940u PCI card to work. I should say right out that i'm an inexperienced linux user, although i understand the basics and am in general 'computer competent'. I know, for instance, that this card is supposed to use a aic7xxx driver which i is already included in my fedora build (a very vanilla build).

It's working somewhat - I can enter the BIOS when i reboot, and it even detects the name of the device I attach to it (which is an arcane thing: CAMAC crate controller - physicists use a 40 year old IEEE protocol for ADC's and other tasks. the crate talks to the computer via a 'crate controller' which connects to the computer via scsi. I'm sure the crate controller works cuz it was working on another, older, windows machine). However, after it detects the jorway crate controller, it says,

"
Int 13h Device Not Found
BIOS not installed
"

I am unaware even of a way to see if the hardware is detected once i'm in linux. I konw test programs I downloaded for talkign to the jorway aren't working, they say there's an 'error finding generic scsi device', which I know is a message generated specifically by the test program cuz i have the source code.

what can I do? perhaps more important at this stage is what do you need to know to help me? :)

thanks in advance.

That's normal, if you're not booting off a drive connected to the SCSI card. I assume you're booting off an IDE or SATA drive.

In Linux, you could either load the aic7xxx module manually (modprobe aic7xxx) or build it directly into the kernel. Run /sbin/lsmod to see which modules are loaded.

I've been using an Adaptec 2940UW for years in Fedora with no problem.

that sounds like good advice, but....

why isn't modprobe recognized?


[minerva@tesla example]$ modprobe aic7xxx
bash: modprobe: command not found
[minerva@tesla example]$ which modprobe
/usr/bin/which: no modprobe in (/usr/kerberos/bin:/usr/lib64/ccache:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/minerva/bin:.:/home/minerva/bin:.)
[minerva@tesla example]$ lsmod
bash: lsmod: command not found
[minerva@tesla example]$ which lsmod
/usr/bin/which: no lsmod in (/usr/kerberos/bin:/usr/lib64/ccache:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/minerva/bin:.:/home/minerva/bin:.)


i tried executing this commands as root as well, same null result. insmod and rmmod are also missing. friggin tcsh is missing. I am clearly teh n008zOr.

plz to help me escape my ignorance :)

I'm a noob. I apparently need to use modprobe to install a particular module to use a particular piece of hardware (see http://forums.fedoraforum.org/showthread.php?p=969792#post969792 for optional background)

however modprobe doesn't seem to be available, nor does lsmod, insmod, rmmod, leaving me confused. also, basics like tcsh are missing. is there a package i need to download?

I am running up-to-date fedora on a brand new dell optiplex 755

Hello:

Those commands are generally available and usable only to the root user (aka super-user, system administrator, etc.). You must run them as root user.

whereis found it, thanks! i wasn't aware of that command.

i found modprobe in /sbin/ . is there a reason not to put /sbin/ in PATH?

Hello:

Yes: the command will fail if you are not root user, since only root user can load kernel modules. That's why normal users by default don't have /sbin or /usr/sbin in their PATH.

V

ok, so modprobe is in /sbin/, as is lsmod.

so once i've got the aic7xxx module loaded, is there some simple way to test whether the computer sees the hardware and the two are getting along, all friendly-like?

dan, thanks for the heads up.

Locating command line utilities didn't/doesn't seem like a hardware problem (for all i knew there was a missing package in my OS or something), so I thought the software forum would be the appropriate place to look for help on that issue. I didn't intend to spam the board. My intent was to ask questions in the appropriate forum. While I may see the issue as separate, clearly it's up to the mods to determine protocol, chaos being the alternative.

in any case, the current status of my problem using my aha-2940u is that the module is loaded but i don't know if my compy can see the pci card or communicate with it, and i don't know how to find the answer.
