3.7.0 HP StorageWorks HP Scalable NAS File Serving Software upgrade guide HP Scalable NAS for Linux (AG513-96005, October 2009)

The installation creates the directory structure /opt/polyserve/lib/kernels.
RPMs for the binary, source, and debug kernels are in the kernels directory.
Then build the kernel using the appropriate source kernel RPMs from the kernels RPM
that you just installed. See Appendix B, page 99 for more information.
3. HBA drivers and HP Scalable NAS
When configuring the operating system, you will need to consider whether the HBA
driver should be loaded either during the initial booting of the kernel or when HP
Scalable NAS is started. The following scenarios describe the appropriate action for
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 os documentation
for more information.)
