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.

QUESTION: 9

You are replacing a boot device on a FAS8300 system that is running ONTAP 9.10P6 software. You attach a USB memory stick to the external USB port on the storage controller but cannot access the memory stick.
What step needs to be performed to access the boot device?

Set the port to "enabled" with setenv.
You need to use ONTAP 9.11 or later software.
Add the boot device before the BIOS is loaded.
The external USB port is not activated on NetApp systems.

Answer(s): A

Explanation:

When replacing a boot device on a FAS8300 system and using a USB memory stick for recovery or installation, the external USB port must be explicitly enabled. This is done through the setenv command in the boot environment.

Steps to Enable the External USB Port:
Reboot the system and interrupt the boot process to access the bootloader prompt.
At the bootloader prompt, use the following command:

arduino
Copy code setenv usbport_enabled true
Save the configuration and proceed with the boot process.

Why Other Options Are Incorrect:
B . You need to use ONTAP 9.11 or later software:
ONTAP 9.10P6 fully supports external USB recovery. There is no need to upgrade to ONTAP 9.11 for this functionality.
C . Add the boot device before the BIOS is loaded:
While the USB device must be inserted during the boot process, this alone will not enable access unless the port is enabled via setenv.
D . The external USB port is not activated on NetApp systems:
This is incorrect. The external USB port is supported but must be explicitly enabled in the bootloader environment.

Reference:

NetApp Hardware Installation Guide for FAS8300 systems outlines the steps for enabling the USB port during recovery.
"ONTAP Boot Troubleshooting Guide" specifies the use of the setenv command to activate USB ports.

QUESTION: 10

Which type of core file is generated when a node panics?

mgwd core
user space core
sync core
kernel core

Answer(s): D

Explanation:

When a node panics in ONTAP, a kernel core file is generated. This core file contains information about the kernel's state at the time of the panic and is essential for debugging system crashes.

Key Details:
A kernel core file is produced during a node panic to capture information about the kernel, memory, and processes that led to the crash.
The core file is stored on the root aggregate by default and can be uploaded to NetApp Support using the autosupport invoke-core-upload command.

Why Other Options Are Incorrect:
A . mgwd core:
This is related to the Management Gateway daemon, which handles management traffic. It does not generate a core file during a panic.
B . user space core:
User space cores are generated for processes running in user space, not for kernel panics.

C . sync core:
Sync cores refer to synchronized cores for debugging but are not the primary type generated during a node panic.

Reference:

"ONTAP Panic Troubleshooting Guide" specifies kernel core files as the output of a node panic. "ONTAP Core File Management Guide" details the handling of kernel core files after a crash.
