Abstract
Embodiments are described for systems and methods that facilitate control of virtual endpoint failover/failback operations in a SCSI target network environment. During failover, SCSI target virtual endpoints failover to a secondary SCSI target port when the primary port fails, and failback to the primary port when the primary port is corrected. Embodiments include a method of efficiently controlling failover and failback operations of virtual endpoints where such operations may have different operating characteristics and be asynchronously initiated, and a method of globally or selectively cancelling failover and failback operations based on multiple system and operating conditions.
