According to this page, cciss is replaced by hpsa.

http://cciss.sourceforge.net/

Also:

"NOTE: The hpsa driver is a SCSI driver, while the cciss driver is a block driver. This means that logical drives which would be presented with devices nodes like "/dev/cciss/c0d0", etc. will now be presented as "/dev/sda", etc
...
The hpsa driver is available in the kernel.org kernels, and in RHEL6 by default."

Does HP offer driver? They tend to have some of the best linux support.

This means that if you are currently using cciss with the above controllers and decide to switch to hpsa, you've got to adjust your /etc/fstab, grub configuration files, etc. to make this work.

can change generic driver to HPSA ?

For a new install of a distribution using the hpsa driver, the "cciss.cciss_allow_any=1" boot parameter should allow hpsa to be used easily.

can install centos with cciss driver ? (if i add this option in boot)

Looks like hpsa is now the default in the kernel. If you want to go back to cciss, you may have to build the module yourself and load it instead of hpsa using modprobe. If you are booting from these drives then grub and initrd have to include the right module.
