Reducing application downtime during failover including identifying a critical line in the startup of an application, the critical line comprising the point in the startup of the application in which the application begins to use dependent resources; checkpointing the application at the critical line of startup; identifying a failure in the application; and restarting the application from the checkpointed application at the critical line.

Reducing application downtime during failover

Provided are systems and methods for accessing a storage device from a node when a local connection failure occurs between the node and the storage device. A failure is determined to have occurred at a first node access path between a first node and a storage device that prevents an application at the first node from accessing the storage device from the first node access path. An access request is sent from the first node to a second node. The second node has a second node access path to the storage device. A determination is made that the second node can communicate with the storage device. The storage device is accessed by an application at the first node via the second node access path.
