replace fail disk

a disk failed and has been replaced.

disk show -n

  DISK       OWNER                      POOL   SERIAL NUMBER         HOME 

------------ -------------              -----  -------------         ------------- 

0a.02.10     Not Owned                  NONE   WD-WCAW30940466    

what do I do to put this back?

Re: replace fail disk

Go to the system where you want this disk to be assigned and run command "disk assign 0a.02.10" and after that check in the spare disk section if this disk is visible.
