Abstract
A method and apparatus are provided for implementing distributed (SCSI) devices using enhanced adapter reservations. A plurality of adapters is provided. Each adapter implements a plurality of logical devices with each logical device respectively coupled to a port of the distributed SCSI devices. The adapters manage reservations for the plurality of logical devices selectively using a no reservation state, an implicit reservation state, and an explicit reservation state. The adapters arbitrarily assign one adapter for managing each of the plurality of logical devices.
