❍ Verify if SCSI functionality is loaded as a module by using the following command:

lsmod

■ If scsi_mod and sd_mod are listed in the output, add the following line to the modules.

conf file:

options scsi_mod max_scsi_luns=255 scsi_allow_ghost_devices=1

■ If scsi_mod and sd_mod are not listed in the output of the lsmod command, modify

the kernel line of the new boot record in the grub.conf file:

kernel /vmlinuz-kernel_version ro root=LABEL=/ max_scsi_luns=255 scsi_allow_ghost_devices=1

Below is an example of the grub.conf entry if SCSI functionality is built into the kernel.

title Red Hat Linux with Emulex driver (2.4.21-4.ELsmpl)

root (hd0,0)

kernel /vmlinuz-2.4.21-4.ELsmp ro root=LABEL=/ max_scsi_luns=255

scsi_allow_ghost_devices=1

initrd /initrd-2.4.21-4.ELsmp-elx.img

Note

The lpfc_skip_luns parameter located in the/etc/lpfc.conf

file must be set to 1 when the driver is built.

8. The boot image new_image_name must match the name specified in the /etc/grub.conf file. Run the

following command to build the boot image:

# /sbin/mkinitrd -f /boot/new_image_name `uname -r`

9. Reboot the system to incorporate the new driver. At the shell prompt, type the following:

# sync

# reboot

10. As the system reboots, you are prompted with GRUB boot. At this point enter the name of the label of

your boot image, new_label in the above example, or just press enter and the default boot image will

be loaded.
