System Driver Parameter max_scsi_luns

Support for multiple LUNs can be configured in one of three ways. Currently, the
maximum number of LUNs that can be scanned for each device is 128.
The kernel must be configured to have multiple LUN support enabled for nonzero
LUNs to be configured and accessible. Use the make menuconfig command to
build a kernel that has the option under SCSI Support enabled to probe all LUNs
on SCSI devices. See the BUILD_KERNEL.txt file for more information on the make
menuconfig command.
NOTE:
To configure multiple LUN support during boot time, type the following at the boot
■
prompt:
boot: linux max_scsi_luns=128
If the SCSI Mid-Layer is compiled as a module, add the following line to the
■
/etc/modules.conf file to scan for multiple LUNs at each boot:
option scsi_mod max_scsi_luns=128
NOTE: You must create a RAMDISK image for this modification to take effect.
If the SCSI Mid-Layer is compiled in the kernel, the boot loader can be configured
■
to scan for multiple LUNs each time the system boots.
For LILO, perform the following steps:
1. Add the following line to each of the kernel images listed in the /etc/lilo.conf
IS0053302-00 7
now the default boot image.
title Red Hat Linux-newKernel (2.4.7-10)
root (hd0,0)
kernel /newKernel ro root=/dev/hda2
now the default boot image.
If you have multiple HBAs, set max_scsi_luns to the largest number of
LUNs supported by any one of these HBAs.
