Updating Qlogic HBA firmware? Or bundled with the Driver?

Jump to solution

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?

I can confirm it's bundled, too.

Before I install ESXi 5.1, I upgraded firmware to 7.0 manually. Once ESXi is installed, I found firmware was downgraded to 5.0 which comes with stock driver. Then I upgraded the driver, firmware was upgraded to 7.0 again.

Neat article.  I hate to say it but I would post a reply to Cormac that guy knows his stuff.  I assume this means that Qlogic got sick of the drive / firmware being out of sync so during a ESXi load it flashes the firmware if needed to match the driver being loaded... but best to ask Cormac.

Thanks. I tested it to in a 5.5 host. and then checked everything via /proc/scsi/etc before and after. Pretty cool. Now if only all my emulex cards would this Smiley Happy
