An administrator enabled the iSCSI protocol on an SVM and created a LUN for a Windows 2012 server. When the administrator uses Windows Disk Management, the LUN cannot be found. What are two…
The correct answer is C. Define the iSCSI IQN in the igroup and map to the LUN. D. Start the iSCSI service on the Windows 2012 server. To make an iSCSI LUN visible to a Windows server, the server's iSCSI service must be running, and its iSCSI Initiator Name (IQN) must be defined and mapped to the LUN within an igroup on the NetApp storage system.
Question
An administrator enabled the iSCSI protocol on an SVM and created a LUN for a Windows 2012 server. When the administrator uses Windows Disk Management, the LUN cannot be found. What are two solutions for this problem? (Choose two.)
Options
- ASet up the Windows 2012 server to serve as an iSCSI target for the LUN.
- BDefine the iSCSI Send Targets in the igroup and map to the LUN.
- CDefine the iSCSI IQN in the igroup and map to the LUN.
- DStart the iSCSI service on the Windows 2012 server.

Why each option
To make an iSCSI LUN visible to a Windows server, the server's iSCSI service must be running, and its iSCSI Initiator Name (IQN) must be defined and mapped to the LUN within an igroup on the NetApp storage system.
The Windows 2012 server needs to act as an iSCSI initiator to consume the LUN from the NetApp storage, not as an iSCSI target.
"iSCSI Send Targets" is a discovery method used by an iSCSI initiator to find available targets, but it's not a configuration step on the NetApp igroup itself that would grant access; defining the IQN and mapping the LUN are the necessary steps.
For a Windows server to access an iSCSI LUN, the server's iSCSI Initiator Name (IQN) must be added to an initiator group (igroup) on the NetApp SVM, and that igroup must then be mapped to the LUN, granting the server access.
The iSCSI Initiator service on the Windows 2012 server must be running to discover and connect to iSCSI targets; if the service is stopped, the LUN will not be found.
