Installing or Updating the HBA Driver

Install or Update the HBA

Driver

1. Install any updates, such as hot fixes or patches, to the server’s

operating system that are required for the HBA driver version
you are installing.

2. After installing any updates, reboot the server.

3. Install the driver following the instructions on the HBA vendor’s

website.

4. If you installed the QLogic HBA driver, set the parameters in the

/kernel/drv/qla2xxx.conf

file to the values required for

PowerPath as described in the HBA driver instructions.

5. Reboot the server when the installation program prompts you to

Some driver updates may require you to reboot the server.

6. If the installation program did not prompt you to reboot, reboot

the server when the driver installation is complete.
