Installing the Linux Driver

FCA2214/FCA2214DC PCI-X Host Bus Adapters for Linux, NetWare, and Windows Installation
Guide
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”
