    The IDD can be accessed exclusively in the multi-host or multi-initiator environment by using the reserve and release functions. (10) Enclosure service function The IDD supports the enclosure service interface (ESI), which complies with SFF-8067. The ESI interface enables use of the SCSI-3 enclosure
