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.

NOTE: If you have multiple HBAs, set max_scsi_luns to the largest number of

LUNs supported by any one of these HBAs.

■

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 not compiled as a module, 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

file:

append="max_scsi_luns=128"
