Changing the Emulex HBA Inbox Driver Parameters
See “Modifying the /etc/modprobe.conf File and Building the Ramdisk” (page 33) of this document
for changing the Emulex HBA parameters and rebuilding the ramdisk.
Installing the New QLogic Driver
To install a new QLogic driver to replace the Linux inbox driver, complete the following steps:
1. Go to the following website:
QLogic
Download the driver package qlafc-linux-<version>-install.tgz to the RHEL host.
2. To extract the files, run the following command:
# tar xvzf qlafc-linux-<version>-install.tgz
3. From the directory where the file was extracted, change to the driver directory:
# cd qlafc-linux-<version>-install
4. Run qlinstall --upgrade to install the new driver:
# ./qlinstall --upgrade
Required
You must use the --upgrade requirement for a successful driver installation.
NOTE: You can also use the -up option with the qlinstall command. Make sure the
-up or the -upgrade option is used when installing the new driver. Upgrade builds and
installs the QLogic HBA driver, installs the SNIA HBA API library, creates ramdisk to load
driver at boot time, does not load and unload current drivers and does not do persistent
binding.
5. After the installation completes, reboot the RHEL host. When the host comes back up, check
the driver version:
# modinfo qla2xxx |grep version
version: xx.yy.zz
NOTE: Modify the HBA parameter to set qlport_down_retry to 10 if the HP 3PAR
StoreServ Storage array is running HP 3PAR OS 3.1.1 or later. But if the HP 3PAR StoreServ
Storage array is running an HP 3PAR OS version earlier than 3.1.1, set qlport_down_retry
to 1 rather than 10. However, do NOT use the procedure to rebuild the ramdisk as described
in “Building the QLogic Driver” (page 38). Instead, use the scli utility that was installed during
the driver install process to change this HBA parameter value.
