Installing the Linux Driver
32 A6826A PCI-X Host Bus Adapter for Linux 64-bit Systems 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. If your system has a previous version of the qla driver, 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_release_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
