Unshare a Dedicated Host that is shared with other AWS accounts
The Dedicated Host owner can unshare a shared Dedicated Host at any time. When you unshare a shared Dedicated Host, the following rules apply:
-
Consumers with whom the Dedicated Host was shared can no longer launch new instances onto it.
-
Instances owned by consumers that were running on the Dedicated Host at the time of unsharing continue to run but are scheduled for retirement. Consumers receive retirement notifications for the instances and they have two weeks to take action on the notifications. However, if the Dedicated Host is reshared with the consumer within the retirement notice period, the instance retirements are cancelled.
To unshare a shared Dedicated Host that you own, you must remove it from the resource share. You can do this by using one of the following methods.
