Paul M. Wright, jr. spake the following on 10/20/2006 8:49 AM:

I am running CentOS 4.4 and trying to bring up my tape library. When I do cat /proc/scsi/scsi, it shows only the drive and not the changer although both are shown when the Adaptec card initializes.

I recall in the distant past that I had to do "something" to get the kernel to properly scan the SCSI bus for the additional LUN but I cannot for the life of me recall what that was. It would have also been a much earlier kernel.

Can anyone here help me out?

Regards,

paul

add options scsi_mod "max_luns=16" to /etc/modules.conf and rebuilt the initrd image, then reboot. I think this was max_scsi_luns in 2.4 kernels. If one doesn't work, try the other.
