I can confirm that da10 is still the new disk I put into place of prior da3.

So list out what diskid/DISK-K1GMBN9D, diskid/DISK-K1GMEDMD... to diskid/DISK-3WJ7ZMMJ are in terms of /dev/da* actually are. I have some controllers that will re-order the disks on every reboot. glabel status and camcontrol devlist should help verify
camcontrol devlist lets me know that the three HGST drives making up
zraid1-1 are da3,da4,da5 and the three WD drives making up
zraid1-2 are da6,da7,da8. So, like before, just moved down a
number because the prior da3 went away and a new disk in that
physical slot became da10. (da9 is a loose JBOD single with ufs
on it, previously da10, in slot 12 of 12)
da10 is in fact still the disk in slot3 of the chassis, zdb -l shows
the below. I did add and remove it as a spare while trying things,
that may be why it shows up this way.
