Abstract
Method and apparatus for performing proactive input-output (IO) failover based on predicting optical transceiver module hardware failures in a host bus adapter (HBA) are described. An example method includes registering with an HBA to receive a notification that a first path via the HBA is predicted to fail. The notification is based on a set of parameters of an optical transceiver module coupled to the first path. A set of parameters of the optical transceiver module are monitored in accordance with the registration. At least one of the set of parameter is determined to satisfy a predetermined criteria. Responsive to the determination, the notification that the first path via the HBA is predicted to fail is sent, a second path via the HBA for issuing an IO operation is determined, and the IO operation is issued via the second path.
