Have you check if your aacraid module is correctly loaded ?

You can check it thru “lsmod” command.

If not, you probably need to recompile your kernel with this option :
CONFIG_SCSI_AACRAID=m
And comment this one if you have it :
CONFIG_SCSI_AIC7XXX=m

I remember that there is conflict between the both modules which doesn’t manage the same PERC version card.

Thanxs for your quick answer.

I’ve checked entries in my /proc/devices files and effectly there isn’t any aac entry in it…

I think there is an hardware error or perhaps my configuration isn’t compatible with aac!

Bye.

I suggest you to check for an “aac” entry in your /proc/devices. If you don’t have this entry there is probably a mistake in the hardawre detection :)

If you have it, you can try to add the node entry manually by this command:
mknod afa0 c XXX 0
chmod 600 afa0

Where XXX equal the value in your /proc/devices for “aac”.

Take a look at the script /dev/MAKEDEV.afa

When I run the “/MAKEDEV.afa afa0″ command, I’ve the error “./MAKEDEV.afa: Can not derive the major number for device afa.” which appear. I have changed the devname value to ‘aac’ in the MAKEDEV.afa file but the problem persist. Is someone have an idea to resolve it ? Thanks.

P.S. : I’m running under Centos 4.4 (Redhat 9).
