Network Appliance NetApp Accredited Hardware Support Engineer Sample Questions (Q53-Q58):

NEW QUESTION # 53
A node has panicked with a PCI/NMI error. Giveback has not been performed.
Which two commands should you run to collect the logs to determine the cause? (Choose two.)

A. show pci -v
B. event log show
C. rdfile /mroot/etc/log/SSRAM
D. pelog -a -g=2

Answer: C,D

Explanation:
To diagnose a PCI/NMI error and collect logs, use the following commands:
* What it does:This command collects PCI error logs, including detailed information about PCI devices and the errors that caused the panic.
* How to use:Run the command from the nodeshell to capture the required PCI log entries.
1. pelog -a -g=2
* What it does:This command reads the SSRAM log file, which contains low-level error information related to PCI and other hardware subsystems.
* How to use:Run the command to view the log entries directly for detailed troubleshooting.
2. rdfile /mroot/etc/log/SSRAM
* B. show pci -v:
* While this command displays PCI device information, it does not provide detailed error logs.
* D. event log show:
* This displays event log entries but does not contain the specific PCI or NMI-related logs required for diagnosing the panic.
Why Other Options Are Incorrect:
* "ONTAP Hardware Troubleshooting Guide" lists pelog and SSRAM as tools for analyzing PCI errors.
* "ONTAP Panic Analysis Guide" emphasizes the importance of collecting detailed hardware logs.

NEW QUESTION # 54
Which two tools can be used to recover an inconsistent aggregate? (Choose two.)

A. wafl snapiron
B. file check
C. wafliron
D. wafl_check

Answer: C,D

Explanation:
To recover an inconsistent aggregate, the following tools can be used:
* What it does:This tool is used to perform a consistency check on WAFL metadata. It identifies and attempts to fix WAFL inconsistencies in aggregates.
* When to use:Run wafl_check after identifying WAFL inconsistencies to repair minor metadata issues.
1. wafl_check
* What it does:This tool repairs WAFL inconsistencies by reconstructing metadata. It is more powerful than wafl_check and should only be run under NetApp Support guidance, as improper use can result in data loss.
* When to use:Use wafliron for severe WAFL inconsistencies that cannot be resolved by wafl_check.
2. wafliron
* A. file check:
* This is not a valid NetApp tool.
* C. wafl snapiron:
* While similar in name, snapiron is used for snapshot recovery, not aggregate recovery.
Why Other Options Are Incorrect:
* "ONTAP Aggregate Troubleshooting Guide" details the usage of wafl_check and wafliron.
* NetApp Support documentation provides guidelines for recovering inconsistent aggregates.

NEW QUESTION # 55
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?

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

Answer: 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.
* Use the following command:
Steps to Collect Shelf Logs: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.
* 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.
Why Other Options Are Incorrect:
* "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.

NEW QUESTION # 56
Where is a kernel core file stored on a FAS9000 system that is running ONTAP 9.12.1 software?

A. on the root aggregate
B. on the mailbox disk
C. on the boot device
D. on the partner root aggregate

Answer: A

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.
* 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.
Key Details:
* 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.
* "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.

NEW QUESTION # 57
Which two steps are required to replace a drawer in a DS460c shelf? (Choose two.)

A. Disconnect the cable chains from the chassis.
B. Shut down both nodes.
C. Power off the shelf.
D. Evacuate all drives in the drawer.

Answer: A,D

Explanation:
To replace a drawer in a DS460c shelf, the following steps must be taken:
* Why this is required:Cable chains connect the drawer to the shelf and must be disconnected to safely remove the drawer.
1. Disconnect the cable chains from the chassis
* Why this is required:Drives must be removed to avoid damage during the drawer replacement process and to reduce the weight of the drawer for safe handling.
2. Evacuate all drives in the drawer
* A. Shut down both nodes:
* This is unnecessary because DS460c shelves support online replacement, and the system can remain operational.
* C. Power off the shelf:
* This is also unnecessary. DS460c shelves are hot-swappable, meaning they do not require the shelf to be powered down.
Why Other Options Are Incorrect:
* "DS460c Hardware Service Guide" explains the procedure for replacing a drawer.
* NetApp's "Field Replacement Guide" for DS460c shelves emphasizes online and hot-swappable replacements.
