I am getting ready to start reinstallation of esxi 5.1 clusters to 5.5. In doing this I am getting all the firmware upgraded. We are System X so IBM has a pretty good bundler of everything. The one exception was for the Qlogic 2562 which was an optional update. I am bios 3.2 and firmware 5.1. Newer bios is 3.24 and I don't say any groundbreaking fixed. I cannot find any information on the newer firmware, so I was deciding to update it anyway when I came across this link which states that there is no need to update the firmware on the Qlogic HBA, the drivers do it themselves?

Can someone explain this is more depth to me, and is it true?
