    Hey Steve,

    My University has a nice 7410 cluster that has a bunch of J4400 disk arrays attached to it. When I applied this latest update to my production cluster, one head at a time, it went through and updated all the 1TB drives to new firmware. I am wondering how the drives can get firmware updates while they are actively spinning/sharing their data?

    Thanks for the great blog, keep those posts coming!

    Great question. Anytime someone says "Great question", that is code for "I don't know". No joke, remember that for everything in life. Now, I do know some of it... if the pool is a mirror or RAID stripe, it can easily update the disk firmware one drive at a time and offline a drive with no problem. I have sent a question out to the rest of my group to ask what happens in the case of a pure stripe (RAID 0) pool, where even one drive coming off-line will kill you. I will post the answer when I find out.
