NetApp NS0-521 Exam - Topic 7 Question 10 Discussion

Actual exam question for NetApp's NS0-521 exam

Question #: 10
Topic #: 7

An administrator configured an SVM with LUNs with two WWPNs per node. The administrator accidentally created a WWPN on node1 that needs to move to node2. The SAN hosts use ALUA.

Based on this requirement, what must be taken offline to correct the situation?

ALIF

BLUN

CSVM

DVolume

Show Suggested Answer

Suggested Answer: A

To move a WWPN from node1 to node2 in a NetApp ONTAP SAN environment where ALUA is used, you must take the Logical Interface (LIF) offline. Modifying LIFs involves changing their assignment between nodes, which requires them to be temporarily offline. This ensures that the path states are correctly updated without causing disruption to the SAN hosts.

This seems tricky, but LIF sounds correct!

I thought it might be the SVM, but LIF makes more sense.

Wait, are we sure it's not the LUN?

You need to take the LIF offline.

I’m leaning towards the volume needing to be taken offline, but I can't recall the specifics on how that impacts the WWPNs.

Could it be the SVM itself? I feel like we discussed how changes to the configuration might require that to be offline.

I'm not entirely sure, but I remember something about needing to take the LUN offline in a similar practice question.

I think we might need to take the LIF offline since it's related to the network interface for the SVM.

Hmm, I'm not sure. I'll need to review the ALUA details again to determine if the LIF or Volume would also need to be considered.

I'm pretty confident the answer is B. The LUN would need to be taken offline to correct the WWPN issue without impacting the other hosts.

Wait, I'm a bit confused. Wouldn't the SVM need to be taken offline instead? That seems like the logical step to me.

Okay, I think I've got this. Since the WWPN needs to move between nodes, the LUN would need to be taken offline to make that change.

Hmm, this seems like a tricky one. I'll need to think through the ALUA configuration and how that impacts the WWPN changes.

B) LUN is the way to go. Hopefully, the admin doesn't mix up the WWPN again - that would be a real clown show!

I agree with Nan, moving the WWPN to node2 would require taking the LUN offline.

I'll go with B) LUN as well. Can't believe the admin made that mistake, but at least it's an easy fix.

Hmm, B) LUN sounds right. Doesn't make sense to take the whole SVM or volume offline just to fix a WWPN on one node.

I think the correct answer is B) LUN. We need to take the affected LUN offline to correct the WWPN issue without disrupting the entire SVM or other volumes.
