<font face="Helvetica, Arial, sans-serif">Hi guys,<br>
<br>
I do have two zpools of mirrored vdevs, where each vdev is spread
over two LSI 9207-8i HBAs. Is it possible to perform a round-robin
FW upgrade on the LSI HBAs, without rebooting the box? I'd like to
keep the zpools up while I am performing the upgrade and I thought
of breaking the mirrors, performing the FW upgrade on the first
9207, re-attaching the devices and doing the same again for the
other half of the zpools vdevs.<br>
<br>
Has anyone done this before, or is a host reboot mandantory?<br>
<br>
Thanks,<br>
