I'd guess removing the SLOG altogether might be the safest, so for this
configuration logs mirror-7 ONLINE 0 0 0 c2t22d0 ONLINE 0 0 0 c2t23d0 ONLINE 0
0 0 just `zpool remove zwimming mirror-7`, run `cfgadm -a` to find the full
device path, do `cfgadm -c unconfigure devpath`, replace the drive, run
devfsadm for good measure, check if it's connected with cfgadm -a, and add the
SLOG again. roy ----- Original Message -----
