An administrator enabled the iSCSI protocol on an SVM and created a LUN for a Windows 2016 system. After rescan, the LUN is not visible on the host.
Which two steps must the administrator take to solve this problem? (Choose two.)
A. Create an initiator group (igroup), add the WWPN of the host initiator, and then map the igroup to the LUN.
B. Disable the ALUA support from the host for the LUN.
C. Configure the iSCSI service on the Windows 2016 system.
D. Create an initiator group (igroup), add the iSCSI IQN, and map the igroup to the LUN.
Correct Answer: CD
Explanation/Reference:
D: An iSCSI qualified name (IQN) identifier is a worldwide unique name that each iSCSI initiator and iSCSI target must have. The IQN for an iSCSI initiator is available in Microsoft iSCSI Software Initiator or other iSCSI initiators. Typically the IQN is used by the iSCSI target to identify the iSCSI initiator.
Incorrect Answers:
A: A World Wide Port Name, WWPN, or WWpN, is a World Wide Name assigned to a port in a Fibre Channel fabric. Used on storage area networks, it performs a function equivalent to the MAC address in Ethernet protocol, as it is supposed to be a unique identifier in the network.
B: Asymmetric Logical Unit Access (ALUA), also known as Target Port Groups Support (TPGS), is a set of SCSI concepts and commands that define path prioritization for SCSI devices.
