SOLVED Help. Disk removed from pool with 4 mirrored vDevs - and need to repair

[salty_penguin]

Please help

See below -

I used to have 4 mirrored vdevs (da0+da1,da2+da3,etc), however I accidentally removed da3 from the hotswap bracket.
Now da2 is just showing as a single disk in a vDev, and I'd like to re-add da3 by mirroring it, restoring the prior config.
Any resources on how to do this? I have no redundancy on this vDev right now.

Thanks.
