[OpenIndiana-discuss] Replacing a faulty rpool disk

[EM - SC]

Hi, 
I followed these instructions here:
https://omnios.omniti.com/wiki.php/GeneralAdministration#MirroringARootPool

Resilvering ran ok, I have some chksum in the new disk but it is ONLINE. 

I'm a bit hesitant to remove the faulty disk because it was the original
boot disk. 
But maybe I shouldn't worry, and now that I have a mirror, it will
continue to run without complaining 'where is the boot disk'?

Thanks!
