• Question 149:

  Click the Exhibit button.

  

  A 4-node cluster was expanded with two news nodes (Nodes 5 and 6). You are now attempting to set up four FC LUNs on the two new nodes that use the ps2 igroup name, although FC ping works. LUNs on the previous four nodes are discoverable, but the four new LUNs on the new controllers are not discoverable.

  Referring to the exhibit, what is the problem?

  A. The zones between the hosts and LIFs are from node-05 and node-06.

  B. Selective LUN Mapping (SLM) is not configured for this HA pair.

  C. The portset must be configured to reflect Nodes 5 and 6.

  D. Igroup ps2 has the portset configured with the LIFs.

  Correct Answer: C
