3.7.0 HP StorageWorks HP Scalable NAS File Serving Software installation guide HP Scalable NAS for Linux (AG513-96004, October 2009)

common HP Scalable NAS configurations. You may need to take certain steps to
ensure that the HBA driver is booted at the correct point.
HBA provided with HP Scalable NAS
If you will be using an HBA driver provided with HP Scalable NAS, the HBA drivers
should not be loaded during the initial boot of the kernel. Instead, when HP Scalable
NAS is started, it will load its own HBA driver. The HP binary kernel is preconfigured
to support this operation; you do not need to take any further action.
NOTE:
Although the HP binary kernel automatically removes the HBA drivers from the initrd
image, you will likely see the HBA drivers loaded after the first reboot of the kernel.
The kernel's HBA modules will be exempted from loading after the HP Scalable NAS
rpm is installed and the blacklist is updated.
Third-party MPIO solution
If you will be using a third-party MPIO solution such as EMC PowerPath or IBM RDAC,
the HBA driver must be loaded during the initial booting of the kernel. (The MPIO
drivers are dependent on the HBA drivers and require that they be loaded first.)
When HP Scalable NAS starts later in the boot process, it recognizes the third-party
MPIO driver and does not try to load its own HBA driver. (You may need to take
steps to ensure that the appropriate HBA driver is loaded. See your vendor
documentation for more information.)
SAN boot disk
With certain storage arrays, the boot disk can be on the SAN. In this case, the HBA
driver must be loaded with the kernel so that the boot disk can be located. (You may
need to take steps to ensure that the appropriate HBA driver is loaded. See your
vendor documentation for more information.) You will need to use non-fabric fencing
with this configuration.
Install other HBA drivers
If your configuration requires either an HBA driver version that is provided with HP
Scalable NAS but is not the default, or an HBA driver version that is not provided
with HP Scalable NAS, you can install that version after HP Scalable NAS is installed
