Special Instructions

A kernel compilation is not required when appending the

scsi_allow_ghost_devices parameter to /etc/modules.conf.

Follow these steps to enable the new parameter in

/etc/modules.conf:

1. Change to the appropriate directory and edit the file:

vi /etc/modules.conf

2. Append the following line to the file:

• For Red Hat distributions use:

options scsi_mod max_scsi_luns=255 scsi_allow_ghost_devices=1

Example:

alias parport_lowlevel parport_pc

alias scsi_hostadapter sym53c8xx

alias scsi_hostadapter1 lpfc

alias eth0 tlan

alias scsi_hostadapter2 lpfc

options scsi_mod max_scsi_luns=255 scsi_allow_ghost_devices=1

• For SuSE distributions use:

options scsi_mod scsi_allow_ghost_devices=1

Example:

alias parport_lowlevel parport_pc

alias scsi_hostadapter sym53c8xx

alias scsi_hostadapter1 lpfc

alias scsi_hostadapter2 lpfc

alias eth0 tlan

options scsi_mod max_scsi_luns=255 scsi_allow_ghost_devices=1

options lpfc lpfc_topology=0x02 lpfc_automap=0 lpfc_scan_down=0

lpfc_fcp_bind_WWPN=50060160006000ed:lpfc0t1,50060168006000ed:lpfc0t2,50060160060

00ed:lpfc1t1,50060168006000ed:lpfc1t2

3. Create a new ramdisk to reflect the changes made:

• For Red Hat distributions, use:

cd /boot

cp initrd-

.img initrd-

.img.orig

mkinitrd -v initrd-

.img

where

is the currently running v2.4.x kernel version.

Example:

cd /boot

cp initrd-2.4.21-15.0.4.ELsmp.img initrd-2.4.21-15.0.4.ELsmp.img.orig

mkinitrd –v initrd-2.4.21-15.0.4.ELsmp.img 2.4.21-15.0.4.ELsmp
