Patent ID: 7937617

Claim:
A method comprising: determining that access by a first node in a computation cluster through a first controller to a storage resource has been restored; querying each node in a plurality of nodes to determine whether access to the resource through the first controller has been restored for each node in the plurality of nodes, wherein the plurality of nodes comprises nodes in the computation cluster for which the first controller is a fail-back target, wherein the querying is performed in response to the determining that access by the first node through the first controller to the resource has been restored; receiving a response to the querying, wherein the response indicates that access to the resource through the first controller has been restored for each node in the plurality of nodes; and instructing, based at least in part on the response, the first node to communicate with the resource through the first controller, wherein the instructing the first node to communicate with the resource through the first controller is performed in response to determining that the access to the resource through the first controller has been restored for each node in the plurality of nodes.
