[OpenIndiana-discuss] Duplicate devices in zpool, degraded

[Günther Alka]

Hello David
If you want to move disks around with a controller port based detection, 
you should not just move the disk but insert a new disk on a new 
location followed by a disk replace for a bad disk.

You can replace a disk in the same port but should not insert the 
removed disk in another port (or do a pool export, switch disk and a 
pool import to read new locations)

In your case I would power off and switch the disk in port c2t0d0 to 
another conroller port. After a power on every disk should be on a 
different port what allows a remove of the faulted disk.

If you will find a pool with two missing disks, do a pool export + 
import to re-read all disks with their positions.
