use disks from another HA pair

What is the process of using Disks from another controller of the same model and type as replacements.

I have been trying to add disks that came from another controller and I am able to get the incoming disk in an unowned state.

NAMIA01*> disk show -n
DISK OWNER POOL SERIAL NUMBER HOME
------------ - ------------ ----- ------------- -------------
0d.02.10 Not Owned NONE YFGU75UA

However when ever I try to add to the currentl controller I get this msg

disk assign 0d.02.10 -o NAMIA01
Wed Dec 14 10:15:58 EST [NAMIA01:diskown.changingOwner:info]: changing ownership for disk 0d.02.10 (S/N YFGU75UA) from unowned (ID 4294967295) to NAMIA01 (ID 142241680)
NAMIA01*> Wed Dec 14 10:15:59 EST [NAMIA01:raid.assim.rg.missingChild:error]: Aggregate foreign:aggr1, rgobj_verify: RAID object 0 has only 1 valid children, expected 10.
Wed Dec 14 10:15:59 EST [NAMIA01:raid.assim.plex.missingChild:error]: Aggregate foreign:aggr1, plexobj_verify: Plex 0 only has 0 working RAID groups (1 total) and is being taken offline
Wed Dec 14 10:15:59 EST [NAMIA01:raid.assim.mirror.noChild:ALERT]: Aggregate foreign:aggr1, mirrorobj_verify: No operable plexes found.
Wed Dec 14 10:15:59 EST [NAMIA01:raid.assim.tree.foreign:error]: raidtree_verify: Aggregate aggr1 is a foreign aggregate and is being taken offline. Use the 'aggr online' command to bring it online.
Wed Dec 14 10:15:59 EST [NAMIA01:raid.assim.tree.dupName:notice]: Duplicate aggregate names found, an instance of foreign:aggr1 is being renamed to foreign:aggr1(1).

How can I completly wipe this disk and any other from the Offlined controller so I can use these disks as replacements?

'disk zero spares' ?

You may need to destroy the aggr1(1) aggr before it will zero ...

NAMIA01*> disk show -n
disk show: No disks match option -n.
NAMIA01*>
