Installing the Linux Driver

Note: HP recommends loading the driver using the modprobe command so that any driver parameter value specified in the /etc/modules.conf file takes effect.

e.For Redhat 7.2 with kernel 2.4.9-21 or later, rename the old binary included in the original distribution to ensure that it does not interfere with the updated version as follows:

#cd /lib/modules/<kernel version>/kernel/drivers/addon/qla2300

#mv qla2300.o qla2300_rh.o

After renaming the older driver version, load the new driver using modprobe after updating the dependency file.

2.To manually unload the qla2x00 driver, enter the following command at the command prompt:

# modprobe –r qla2300

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, enter the following command 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

■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”
