NetApp Certified Implementation Engineer – NVMe — Question 52

After adding two nodes to an FC-enabled cluster, the storage administrator wants to ensure that existing LUNs can use paths on the new nodes.
What is required to complete this task?

Answer options

• A. Use the storage port rescan command.
• B. Use the lun mapping add-reporting-nodes command.
• C. Use the lun bind create command.
• D. Rescan the bus on the hosts by using the rescan-scsi-bus.sh script.

Correct answer: B

Explanation

The correct answer is B, as the lun mapping add-reporting-nodes command specifically enables existing LUNs to recognize and utilize the paths from newly added nodes. Option A only rescans the storage ports, which does not ensure LUN accessibility through the new nodes. Option C is irrelevant as it creates new LUN bindings rather than adding existing ones. Option D focuses on rescanning SCSI buses on hosts, which is not the necessary step in this context.
