A customer is testing a newly installed NetApp AFF A400 all-flash HA storage system. An SVM for FCP with a LUN on Node 1 has been configured, and a server has been connected as shown in the exhibit. For testing, the engineer plans to do a storage failover of Node 1.
After the failover, what is the expected status of the marked path?

In the scenario where a storage failover is performed on Node 1 in an HA pair, the path marked in the exhibit would become Active/Nonoptimized. After the failover, the LIFs from Node 1 that were active and optimized will switch to Node 2. Paths that were previously optimized will become nonoptimized because they are now served through the partner node.

This seems too straightforward, I have my doubts.

Nope, it should be Active/Optimized if everything's set up right.

Wait, are you sure? I thought it would be Unavailable.

Totally agree, that's how it works!

The marked path will be Active/Nonoptimized after the failover.

I feel like the path should definitely be Offline, but I need to double-check my notes on failover behavior.

This reminds me of a practice question where the path was still Active but not optimized. Could it be C?

I'm not entirely sure, but I remember something about paths being Active/Nonoptimized during failover scenarios.

I think the path will be marked as Unavailable after the failover since Node 1 is going down.

Hmm, I'm not entirely sure about this one. I'll need to review the NetApp documentation on failover behavior to make the best guess.

Based on my experience with NetApp storage, I'd say the expected status is Active/Nonoptimized. The path will be active, but not the optimal path.

I'm a bit confused by the options here. I'll need to double-check my understanding of how NetApp HA storage systems handle failover scenarios.

Hmm, this looks like a tricky one. I'll need to carefully review the exhibit and think through the storage failover process.

Okay, I think I've got this. After the failover, the marked path should be Active/Nonoptimized, since the LUN is now being served from the partner node.

This is a complex scenario, but I feel confident I can work through it. Identifying the right integration points between the systems is crucial, so Interface Analysis is likely the best technique.

I agree with Gabriele, I think the marked path will be Active/Optimized after the failover.
AL

That makes sense, but wouldn't it be safer to assume it will be Unavailable until confirmed otherwise?
GA
Gabriele

I disagree, I believe it will be Active/Optimized because the failover should ensure continuous access to the data.

That makes sense, but I'm not entirely sure. Maybe we should review the documentation to confirm.

I think the correct answer is C. The path should be Active/Nonoptimized after the failover, since the LUN will now be served by the partner node.
GL
Glenn

Yes, that's correct. The partner node will take over serving the LUN.

I agree with you, the path should be Active/Nonoptimized after the failover.
