When i was checking at the hba adapters, noticed that all of them have the same FRU number except for two of them? will this be cauising the problem. is this normal?

fcs0 & 1 has FRU number 03N5029 while the rest fcs2 -fcs8 10N8620

i would like some suggestions on tunning the hba's to make them achieve their max performance on our system.


Please shed some light on it.
