Network Appliance NetApp Accredited Hardware Support Engineer Sample Questions (Q33-Q38):

NEW QUESTION # 33
Where is a kernel core file stored on a FAS9000 system that is running ONTAP 9.12.1 software?

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

Answer: D

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 # 34
You are reviewing the output of disk show and one of the disks is reporting a container type of "unknown".
What is causing this status?

A. The disk is not owned by a member of the high-availability (HA) pair.
B. The disk does not have an owner.
C. The disk is failed.
D. The disk is in the maintenance center.

Answer: B

Explanation:
Understanding "Container Type: Unknown" in Disk Show Output:
* The "unknown" container type typically indicates that the disk is not properly configured or recognized by ONTAP.
* This status often occurs when a disk does not have an owner assigned.
Root Cause:
* For a disk to be used in an ONTAP system, it must be owned by a member of the high-availability (HA) pair.
* If no ownership is assigned, the disk will not be initialized, resulting in an "unknown" container type.
Steps to Resolve:
* Use the disk assign command to manually assign ownership of the disk.
* Example: storage disk assign -disk <disk_name> -owner <node_name>
NetApp Reference Documentation:
* "ONTAP Disk Management Guide" explicitly states that unowned disks report "unknown" container type until they are assigned to a node.
* This is further detailed in the "ONTAP Troubleshooting Guide" under disk configuration issues.

NEW QUESTION # 35
When you add a new disk to an ONTAP 9.1 system, you see an error that the disk "has raid label with version (16), which is not within the currently supported range (14-15)." What is one possible cause of this error?

A. The disk is a non-zeroed spare.
B. The disk needs to be assigned to the new system.
C. The disk was in a system with a newer version of ONTAP software
D. The disk firmware is too new for ONTAP software.

Answer: C

Explanation:
Explanation of RAID Label Versions:
* Disks in ONTAP systems contain metadata known as RAID labels. These labels store critical information such as ownership, aggregate membership, and versioning.
* The error indicates a mismatch between the RAID label version on the disk and the supported versions of the ONTAP system.
Why Option D Is Correct:
* If a disk has a RAID label created by a newer version of ONTAP (e.g., version 16) and is then inserted into a system running an older version of ONTAP (e.g., supporting versions 14-15), the label will not be recognized.
* This mismatch causes ONTAP to reject the disk.
Resolution:
* Upgrade the ONTAP version to match the RAID label on the disk.
* Alternatively, zero the disk to reset its RAID label, but this will erase all data on the disk.
NetApp Reference Documentation:
* The "ONTAP Disk Management Guide" and "ONTAP Compatibility Matrix" explain RAID label versions and compatibility issues when moving disks between ONTAP systems.

NEW QUESTION # 36
You are using wafliron on an aggregate named homedir on a production system.
When is the data on homedir available?

A. when wafliron is started
B. when the administrator manually onlines the aggregate
C. after the mounting phase of wafliron is complete
D. after Phase 4 of wafliron is complete

Answer: D

Explanation:
When using wafliron to repair WAFL inconsistencies on an aggregate, the aggregate becomes available after Phase 4 of the wafliron process is complete.
* Phase 1: Initial scan to identify inconsistencies.
* Phase 2: Corrects directory and inode structure issues.
* Phase 3: Repairs blocks and metadata.
* Phase 4: Completes final repairs and verification, after which the aggregate can be made available.
Phases of wafliron:
* A. when the administrator manually onlines the aggregate:
* The aggregate cannot be manually brought online until wafliron completes Phase 4.
* B. when wafliron is started:
* Starting wafliron does not make the aggregate available; repairs need to be completed first.
* D. after the mounting phase of wafliron is complete:
* WAFLiron does not have a specific "mounting phase." Mounting happens after Phase 4 completes.
Why Other Options Are Incorrect:
* "NetApp WAFLiron Troubleshooting Guide" explains the availability of the aggregate after Phase 4.
* NetApp Support documentation outlines the phases of wafliron and aggregate recovery.

NEW QUESTION # 37
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

A. HA-RASTRACE.TGZ
B. ALL-COREDUMP.XML
C. SSRAM-LOG
D. PCI-HIERARCHY.XML

Answer: A,C

Explanation:
To analyze the provided panic error, the two sections of AutoSupport that are essential for investigation are:
* 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.
* References:
* 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.
1. HA-RASTRACE.TGZ
* 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.
* References:
* 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.
2. SSRAM-LOG
