A company uses iSCSI for host-to-storage data transfers and iSNS to perform name service. Two storage arrays from the company’s domain recently were taken offline for maintenance. How will the iSCSI hosts be made of aware of that event?
Storage arrays de-register themselves before going offline
iSNS generates Entity Status Inquiry to notify about the event
iSNS server issues change state notification to alert devices
iSCSI hosts poll the iSNS server at pre-established intervals to monitor target availability
