Question

A storage administrator is configuring an iSCSI deployment on a Cisco Nexus/MDS environment and wants to reduce the frequency of full LUN rescans on hosts. A new storage array with additional targets has just been added to the same portal IP. Which iSCSI mechanism allows an already-logged-in initiator to learn about the newly added targets without manually reconfiguring each host?

Accepted Answer

The initiator issues a SendTargets discovery session to the portal, which returns the full list of available targets including the newly added ones

Answer

The initiator relies on iSNS to push a broadcast to all hosts forcing an immediate LUN-level rescan

Answer

The target array sends an unsolicited FLOGI to the initiator advertising the new LUNs

Answer

The initiator uses CHAP renegotiation to trigger automatic discovery of new targets
