A system panic due to an "L2 watchdog timeout hard reset" error occurred. You have found a FIFO message in the SP log.

Which FIFO message Is useful for Investigating this Issue?

Abefore NMI BBSP:C=00 L=00 FIFO: F3 F2 F1 F0 5 B2 0 0 0 80 20 E F E3 C0 C2 3 4 6 7 9 9 A

BBIOS exit BBSP:C=2F L=20 FIFO: 2 C8 C9 C4 24 4 6 18 7 8 11

Cbefore Reset BBSP:C=00 L=00 FIFO:

DONTAP Shutdown BBSP:C=00 L=2F FIFO:

Show Suggested Answer

Suggested Answer: A

= The FIFO message before NMI is useful for investigating the issue because it shows the state of the system before the non-maskable interrupt (NMI) was triggered by the L2 watchdog timeout. The FIFO message contains information about the CPU registers, the stack pointer, the instruction pointer, and the last executed instructions. This can help identify the cause of the system hang or deadlock that led to the watchdog reset. The other FIFO messages are not useful because they show the state of the system after the reset or shutdown, which may not reflect the original problem.Reference=https://kb.netapp.com/onprem/ontap/hardware/Handling_L2_Watchdog_Resets_on_the_FAS8200_and_AFF_A300_platforms

I'm not sure, but option A seems to have the most detailed FIFO message.

Option A looks promising for investigating the L2 watchdog timeout issue.

I recall a similar practice question where we had to analyze FIFO logs, and I think the "before NMI" message had some critical data.

I feel like the BIOS exit message could also provide some context, but I’m not confident if it’s directly related to the watchdog timeout issue.

I think the "before Reset" message might be useful since it could show what was happening right before the panic occurred.

I remember we discussed FIFO messages in class, but I'm not entirely sure which one is most relevant for a watchdog timeout.

The "before Reset" message in option C seems like it could be a good place to start. If the system panicked due to an L2 watchdog timeout, there might be some relevant information in the FIFO right before the reset occurred.

I'm not entirely sure which FIFO message would be the most helpful, but I'll start by looking for any references to the L2 watchdog or reset in the options. That might give me a better idea of where to focus my investigation.

Okay, I think the "before NMI" message in option A might be the most relevant one here. The NMI (Non-Maskable Interrupt) is likely related to the system panic, so that FIFO message could provide some useful clues.

I'm a bit confused by all the hex codes and abbreviations in these FIFO messages. I'll need to make sure I understand what each part of the message represents before I can decide which one to focus on.

Hmm, this looks like a tricky one. I'll need to carefully review the FIFO message details to see which one might be most useful for investigating the L2 watchdog timeout issue.
