QUESTION: 5

Where is a kernel core file stored on a FAS9000 system that is running ONTAP 9.12.1 software?

on the partner root aggregate
on the root aggregate
on the mailbox disk
on the boot device

Answer(s): B

Explanation:

On a FAS9000 system running ONTAP 9.12.1, the kernel core file is stored on the root aggregate. This is the default location where ONTAP writes kernel core files for system-level failures.

Key Details:
The root aggregate is the aggregate that contains the root volume for a given node in the cluster. This aggregate is used for critical system files and logs, including kernel core files.
When a kernel panic or other critical failure occurs, the core dump is written to the root aggregate for later analysis by NetApp Support.

Why Other Options Are Incorrect:
A . on the partner root aggregate: The partner root aggregate is not used for storing core files unless explicitly configured (which is not the default behavior). C . on the mailbox disk: The mailbox disk is used for cluster quorum and configuration information, not for storing core files.
D . on the boot device: The boot device contains ONTAP software and boot files but does not store kernel core dumps.

Reference:

"ONTAP System Administration Guide" specifies that core files are stored on the root aggregate. NetApp's "Troubleshooting and Diagnostics Guide" confirms the default behavior for kernel core file storage.

QUESTION: 6

In the latest MANAGEMENT LOG AutoSupport message, you try to inspect the ENVIRONMENT section but find it empty.
In which section of AutoSupport can you find the reason?

AUTOSUPPORT-BUDGET.XML
HEADERS
AUTOSUPPORT-HISTORY.XML
MANIFEST.XML

Answer(s): A

Explanation:

If the ENVIRONMENT section of the latest MANAGEMENT LOG AutoSupport message is empty, the reason can typically be found in the AUTOSUPPORT-BUDGET.XML file. This file contains information about AutoSupport resource allocation, including what sections were processed and any limits that were hit.

Key Details:
AUTOSUPPORT-BUDGET.XML:
This file provides a summary of the resources (budget) allocated for different AutoSupport sections. If the ENVIRONMENT section is missing or empty, the AUTOSUPPORT-BUDGET.XML file will indicate whether it was skipped due to resource constraints or configuration limits.
Why Other Sections Do Not Apply:
B . HEADERS: This section only contains metadata about the AutoSupport message, such as timestamps and node details. It does not explain missing sections. C . AUTOSUPPORT-HISTORY.XML: This file tracks the history of AutoSupport messages but does not provide information about missing sections.
D . MANIFEST.XML: This file lists the contents of the AutoSupport bundle but does not provide details on why a specific section is empty.

Reference:

"ONTAP AutoSupport Troubleshooting Guide" explains the role of the AUTOSUPPORT-BUDGET.XML file in diagnosing missing or incomplete AutoSupport sections.

QUESTION: 7

You have created a case with NetApp Support for an issue with a DS4246 shelf on an ONTAP 9.12.1 system. They have requested that you provide shelf logs.
What action do you need to take to collect the shelf logs?

Provide the output of the nodeshell command rdfile/etc/log/shelflog.
Invoke an autosupport of type all using Active IQ Unified Manager.
Invoke a diagnostic AutoSupport with the subsystem storage.
Invoke a diagnostic autosupport with the subsystem log_files.

Answer(s): C

Explanation:

To collect shelf logs for a DS4246 shelf in an ONTAP 9.12.1 system, you must invoke a diagnostic AutoSupport specifically targeting the storage subsystem. This action ensures that detailed storage logs, including shelf logs, are included in the AutoSupport bundle.

Steps to Collect Shelf Logs:

Use the following command:
bash
Copy code system node autosupport invoke -node <node_name> -type diagnostic -subsystem storage Replace <node_name> with the name of the node experiencing the issue. This command generates an AutoSupport message that includes logs related to storage subsystems, such as disk shelves and adapters.
Provide the AutoSupport case number to NetApp Support for further analysis.

Why Other Options Are Incorrect:
A . Provide the output of the nodeshell command rdfile /etc/log/shelflog:
While this command allows manual reading of shelf logs, it is not a recommended or comprehensive approach for collecting logs for NetApp Support cases. B . Invoke an AutoSupport of type all using Active IQ Unified Manager:
This action generates a generic AutoSupport bundle, which may not include detailed shelf logs unless explicitly targeted.
D . Invoke a diagnostic AutoSupport with the subsystem log_files:
The log_files subsystem targets general system logs, not storage-specific logs like shelf logs.

Reference:

"ONTAP 9 AutoSupport and Diagnostics Guide" outlines the use of the subsystem storage option for collecting shelf logs.
The "Troubleshooting Storage Subsystems" documentation specifies diagnostic AutoSupport as the method for gathering shelf-related logs.

QUESTION: 8

What are two valid commands that can be used to trigger an AutoSupport? (Choose two.)

::> autosupport history show-upload-details node <nodename>
::> system node coredump upload node <nodename>
::> autosupport invoke node <nodename> type all
::> autosupport invoke-core-upload node <nodename>

Answer(s): C,D

Explanation:

To trigger an AutoSupport message in ONTAP, the following commands are valid:

1. ::> autosupport invoke node <nodename> type all
What it does:
This command manually triggers a complete AutoSupport message of type "all." This includes logs and system information from all subsystems.
How to use:
Run the command: autosupport invoke node <nodename> type all Replace <nodename> with the name of the node for which you want to generate the AutoSupport message.
Why it's relevant:

This is the primary method for triggering a full AutoSupport message manually. It is commonly used during troubleshooting to provide comprehensive system data to NetApp Support.

2. ::> autosupport invoke-core-upload node <nodename> What it does:
This command is specifically used to upload core files (e.g., kernel or user space cores) from a node to NetApp Support for analysis.
How to use:
Run the command: autosupport invoke-core-upload node <nodename>. Replace <nodename> with the name of the node for which you want to upload core files.
Why it's relevant:
If there is a system panic or other critical issue, this command ensures that core files are included in the AutoSupport message for detailed analysis.

Why Other Options Are Incorrect:
A . ::> autosupport history show-upload-details node <nodename>:
This command displays the history of AutoSupport uploads but does not trigger a new AutoSupport. B . ::> system node coredump upload node <nodename>:
This command uploads coredumps directly to a support server but does not trigger an AutoSupport message.

Reference:

"ONTAP 9 AutoSupport Configuration Guide" confirms autosupport invoke as a valid command to trigger AutoSupport messages.
"ONTAP CLI Reference Manual" specifies autosupport invoke-core-upload for core file uploads.
