[OmniOS-discuss] Zpool export while resilvering?

Not an answer to your question, but the approach I'd take is renting a
portable 110V or 220V A/C unit from somebody like spot-coolers.com to get
you through the resilver, then apply the firmware update. (And then I'd
start trying to convince management that it's worth adding a unit
permanently -- our Office Pro 24 24000BTU/hr cost us under $4k back in
2011.)
