 The ONTAP command that will help isolate a possible MTU mismatch is network ping -lif jumbo_01 -vserver svm1_cluster1 -destination 192.168.0.210 -disallow-fragmentation true -packet-size 5000. This command will send a ping packet of 5000 bytes from the logical interface (LIF) jumbo_01 to the destination IP address 192.168.0.210, without allowing fragmentation. If the ping fails, it means that there is an MTU mismatch somewhere along the path. If the ping succeeds, it means that the MTU is consistent and the problem is elsewhere12. References: 1: Check the MTU network setting on the storage system |NetApp Documentation 2: How to adjust the MTU for an ONTAP interface - NetApp Knowledge Base

 = The panic message indicates that the node encountered a fatal error while accessing the PCI card in slot 31. This could be due to a hardware failure, a firmware issue, or a driver problem. The first component to troubleshoot is the PCI card in slot 3, as it is the most likely source of the error. You can use the system node hardware pci show command to check the status of the PCI card and the system node hardware firmware update command to update the firmware if needed2. You can also use the Panic Message Analyzer tool from the NetApp Support Site to determine whether your panic was caused by a known software issue3. References = 1: REBOOT (panic) ALERT - AutoSupport message 2: [system node hardware pci show] 3: [Panic Message Analyzer tool]

= 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. References = https://kb.netapp.com/onprem/ontap/hardware/Handling_L2_Watchdog_Resets_on_the_FAS8200_and_AFF_A300_platforms
