modprobe and lsscsi commands are not working
 

Hello,

I have Fedora 2.6.29. When Im trying to laod a kernel module by using modprobe, its throwing an error message 'Module not found'.
Also, when I use 'lssci' command to see the list of SCSI devices, this also doesn't work, and throws an error 'Command not found'.

However, I have used insmod to load my module and I am able to see its entry in /proc/scsi/scsi file, but why 'modprobe' and 'lssci' are not working. Is there any way to resolve this problem?

Many Thanks.

Hi,

How are you implementing the commands? As root?
:hattip:

Yes, Im running them as root only.

Thanks

When you do 'su' , the commands are :

/sbin/lspci
/sbin/modprobe

To have lspci , modprobe in your path, 'su -' is required.
.....

I have tried using /sbin/modprobe and /sbin/lsscsi also , but they are still not working.
Is there any package which I can install, if there is any, how I can install that. When I do 'rpm -q modutils', it says 'modutils is not installed'.

The package : 'module-init-tools' provides /sbin/modprobe

'pciutils' will provide /sbin/lspci

..

For modprobe to work, your module needs to be in this directory or a subdirectory therein:

If that is true, then you need to execute

which builds a list of modules that modprobe uses to find by name. Then try modprobe again.

-AM

Could you type, as root, on your terminal the fallowing lines:

And give us the output? Also, which Fedora you're using? 13? 12? ...?

Post # 1 :
That is Fedora 11.
But there are no differences between versions,
for 'module-init-tools' + 'pciutils', so far concerns
the commands, they provide.
The two packages are also usualy installed by default.
..

But, is lsscsi a part of lspci? I don't know for Fedora, but for Slackware is in a separate package.

Sorry , I misread the lsscsi part.

# yum install lsscsi
.. will install the package.

Hello,

Thanks to everyone for helping me till this time. I have installed the packages for lsscsi and module-init-tools. I am able to use lsscsi successfully now but still facing some issue with modprobe. When I use modprobe <module name>, its gives an error, <module name> doesn't exist.
I have tried this with and without root, and with and without /sbin path, but still its not working. However, I could install my module properly and able to see it in 'lsscsi' output,and also in /proc/modules file. I have tried evrything what all is suggested here in above comments, but something is still missing!!

Thanks.

If it is a 3rd part module you should tell us how you installed it so we can point out what's missing. Generally, for a 3rd part module, you should build and install it. Afterwards, you should issue a "depmod -a" and then try to use "modprobe <module name>".

I have installed the package 'yum install module-init-tools' for modprobe and when I do 'whereis modprobe', I am able to find it in /sbin/... path. But, still I am not able to load my module using 'modprobe <module name>.It's giving the same error '<module-name> not found'.
I have tried 'depmod-a' command also, but still its not getting through.

Thanks.

Hi,

Just curious, show us the complete 'modprobe' line that you are entering. What is the module you are attempting to load?

If you 'man modprobe' then all the information is there.
