With ZFS, that are 4 identical labels on each physical vdev, in this case a single hard drive. L0/L1 at the start of the vdev, and L2/L3 at the end of the vdev.
As I understand it, part of the reason for having four identical labels is to make it difficult to completely loose the information in the labels. In this case, labels L0 & L1 look ok, but labels L2 & L3 'failed to unpack'. And status says "..the label is missing or invalid." Ok, my theory is that some setting in the bios has got confused about the size of the hard drive, and thinks it's smaller that it was originally. Maybe it thinks the geometry is changed. If it thinks the size of the hard drive has reduced, then maybe that is why it cannot read the labels at the end of the vdev. And maybe it think the two readable labels are invalid because now the 'asize' does not match what the bios is currently reporting. I would switch back to you original bios and try looking at settings for the hard drive geometry. (BTW, this is the sort of situation, where it would have been good to have noted the reported size of the hard drive BEFORE the update.) (And if the above theory is right, having a mirrored pair of identical hard drives would not help, as the bios update may cause an identical problem with each drive.)
