[OpenIndiana-discuss] rpool mirror disk problems when moved to different slot

[Michelle]

Ah, if you're moving a live rpool, that's a bit more complex.

I'd have destroyed the mirror, moved the drive and then re-mirrored...
but only if I'd put another boot on the other drive.

After all, if you've mirrored your rpool, but there's no boot on the
mirror drive, then it will still not boot the mirror drive.
