The scsi_mod has this option max_luns which is the "last scsi LUN". How can I view the current setting and change it?

View current settings:

#systool -v -m scsi_mod

If not on your Debian system yet, you can install systool with

#apt-get install sysfsutils.

-If you don't have the file /etc/modprobe.d/local, create it.
-Add the following line:

options scsi_mod max_luns=n

n is the number you want to have.

Reboot, or remove (modprobe -r) and reinsert (modprobe) the module, and after that check with modinfo.

The modinfo command does not give the current settings (values), only the description of the parameters ... –  Aleksandr Levchuk Nov 13 '10 at 3:46
    
You're right, I overlooked said issue. Maybe try "systool -m scsi_mod"? It's provided in the package "sysfsutils" it seems. –  Hans Nov 13 '10 at 3:58
    
Yes, that works. The command is "systool -v -m scsi_mod" with the -v option. Please edit you answer so others won't have to read the comments. Thanks for your help! -Alex –  Aleksandr Levchuk Nov 13 '10 at 5:28
    
OK, I'm glad it works for you, and changed the answer accordingly. –  Hans Nov 13 '10 at 22:28
