Could you please elaborate on what exactly you mean by "do not fully
support HBA mode"?
HBA mode looks supported on P410i (at least to some degree) because:
*) There is an official method to enable/disable it on these
controllers. Only for itanium-based servers unfortunately.
*) This method is mentioned in various documents from HP regarding
Integrity servers.
*) Controller reacts on the change of corresponging bit in nvram_flags
by immediately removing any configured RAID arrays and by refusing to
configure new arrays. Which is totally expected for HBA mode.
*) HBA mode works for me on P410i with patched driver.
