Abstract
An apparatus, system, and method are disclosed for adapter card failover. A switch module connects a first processor complex to an adapter card through a first port as an owner processor complex. The owner processor complex manages the adapter card except for a second port and receives error messages from the adapter card. The switch module further connects a second processor complex to the adapter card through the second port as a non-owner processor complex. The non-owner processor complex manages the second port. A detection module detects a failure of the first processor complex. A setup module modifies the switch module to logically connect the second processor complex to the adapter card as the owner processor complex and to logically disconnect the first processor complex from the adapter card in response to detecting the failure.
