Topic #: 4
[All NS0-093 Questions]

In which two sections of AutoSupport can you find information to analyze the following panic? (Choose two.)

Panic_Message: PCI Error NMI from device(s):ErrSrcID(CorrSrc(0xf00),UCorrSrc(0x18)), RPT(0,3,0):Qlogic FC 16G adapter in slot 1 on Controller

Show Suggested Answer Hide Answer
Suggested Answer: A, C

To analyze the provided panic error, the two sections of AutoSupport that are essential for investigation are:

1. HA-RASTRACE.TGZ

What it is: HA-RASTRACE.TGZ contains HA (High Availability) system trace logs. It records hardware diagnostics, error traces, and the HA system's response to hardware events. These logs are critical when analyzing hardware-related panics, including those caused by PCI errors.

Why it's relevant to the panic: In the given panic message, the NMI (Non-Maskable Interrupt) error originates from a Qlogic FC 16G adapter. HA-RASTRACE.TGZ will provide detailed diagnostics, including the error reporting from the HA interconnect and other hardware diagnostics. Specifically, it may include information about how the system detected the PCI fault and any actions taken to protect the system state.

How to analyze:

Extract the HA-RASTRACE.TGZ file from the AutoSupport bundle.

Review hardware-related trace messages for entries associated with the PCI bus or the Qlogic FC adapter.

Look for specific error codes or keywords like PCI Error, NMI, or Qlogic.


NetApp's 'AutoSupport Logs and Diagnostics Guide' highlights HA-RASTRACE.TGZ as a primary resource for debugging hardware faults.

The 'Panic Troubleshooting Guide' for ONTAP systems specifies HA-RASTRACE as a key source for identifying NMI-related errors.

2. SSRAM-LOG

What it is: SSRAM-LOG records low-level hardware error details, including PCI device register states and uncorrectable memory errors. It is particularly useful for analyzing errors originating in peripheral hardware like network or storage adapters connected via PCI.

Why it's relevant to the panic: The panic message explicitly references a PCI Error NMI caused by a Qlogic FC adapter. SSRAM-LOG captures detailed state information for PCI devices, which can help identify whether the fault originated in the adapter hardware, the PCI bus, or another related component.

How to analyze:

Extract the SSRAM-LOG from the AutoSupport bundle.

Search for PCI-related errors, including the specific error source IDs (e.g., ErrSrcID(CorrSrc(0xf00),UCorrSrc(0x18))).

Review the log entries to confirm the root cause of the NMI.

The 'Hardware Diagnostics and Troubleshooting Guide for ONTAP' lists SSRAM-LOG as a key file for debugging PCI errors.

NetApp's documentation on PCI diagnostics emphasizes the use of SSRAM-LOG for validating hardware-level faults.

This panic message sounds like a real head-scratcher. Time to put on my detective hat and dig through those log files! *adjusts imaginary hat*

I'm going to go with options A and D. The PCI-HIERARCHY.XML file should have the details on the PCI adapter, and the HA-RASTRACE.TGZ might have some additional logs that could be helpful.

I'm not sure, but I think PCI-HIERARCHY.XML could also have some useful information.

I agree with Lenna, those two sections seem relevant for analyzing the panic message.

I think the information can be found in HA-RASTRACE.TGZ and ALL-COREDUMP.XML.

Hmm, the HA-RASTRACE.TGZ and ALL-COREDUMP.XML files also seem like they could have relevant information. Better check those too just to be sure.

User 2: Yeah, and we should also look into the ALL-COREDUMP.XML file for more information.

The PCI Error NMI information would definitely be in the PCI-HIERARCHY.XML file. That's where I'd look first for any PCI-related errors.
