Method, apparatus, and computer usable program code for migrating virtual adapters from source physical adapters to destination physical adapters

An apparatus, in a data processing environment, that includes a plurality of host computer systems that are coupled to a plurality of adapters using a fabric for migrating a virtual adapter from a source physical adapter to a destination physical adapter, said apparatus comprising:

• said apparatus including a configuration manager;
• said configuration manager causing said virtual adapter to stop processing transactions;
• said configuration manager capturing all in-flight transactions that are associated with said virtual adapter;
• said configuration manager migrating said virtual adapter to said destination physical adapter by moving configuration information for said virtual adapter from said source physical adapter to said destination physical adapter;
• said configuration manager restoring said in-flight transactions;
• and
• said configuration manager restarting said virtual adapter on said destination physical adapter, wherein said virtual adapter is included in said destination physical adapter and wherein said virtual adapter begins processing transactions.
