To check autoloader/library detected or not, give command

root@indiangnu.org:/home/arun# cat /proc/scsi/scsi

If it is not show changer, Do following steps

Check the version of Redhat Linux

If it is Redhat Linux 3

Add following line in /etc/modules.conf

“options scsi_mod max_luns=255”

“options scsi_mod scsi_noreportlun=1”

If it is Redhat Linux 4

Add following line in /etc/modprobe.conf

“options scsi_mod max_luns=255”

“options scsi_mod scsi_noreportlun=1”

Then create new initrd file…..

root@indiangnu.org:/home/arun# cd /boot

Rename initrd file

root@indiangnu.org:/home/arun# mv initrd-`uname –r.img initrd-`uname-r.main

e.g. mv initrd-2.6.9-42.EL.img initrd-2.6.9-42.EL.main

root@indiangnu.org:/home/arun# mkinitrd initrd-`uname –r`.img `uname –r`

e.g. mkinitrd initrd-2.6.9-42.EL.img 2.6.9-42.EL

At the end REBOOT your Linux box.

and again you have to re-scan. using first command cat /proc/scsi/scsi
