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

NEW QUESTION # 53
What are the two steps to unfail a disk in maintenance mode? (Choose two.)

  • A. Use the "disk unfair command.
  • B. Reseat the disk.
  • C. Remove it from the Failed Disk Registry.
  • D. Use the disk remove command.

Answer: A,C

Explanation:
Steps to Unfail a Disk in Maintenance Mode:
* When a disk is marked as "failed," it is added to the Failed Disk Registry and marked as unusable by the system. Unfailing a disk involves removing it from this registry and resetting its state.
Step 1: Remove the Disk from the Failed Disk Registry
* Use the command: registry remove <disk> to delete the disk from the Failed Disk Registry. This clears its "failed" status.
Step 2: Use the Disk Unfail Command
* Execute the disk unfail <disk> command to reset the disk status and make it available for use.
Key Notes:
* After unfailing, the disk will be treated as a spare and must be reassigned or re-added to an aggregate.
* If the disk remains failed after these steps, physical hardware issues may need to be addressed.
NetApp Reference Documentation:
* The "ONTAP Maintenance Mode Guide" and "Disk Management Guide" provide detailed instructions for handling failed disks and using the disk unfail command.


NEW QUESTION # 54
What are two options to remove Failure Byte on disks that are marked as failed? (Choose two.)

  • A. Reseat the disk.
  • B. Update the disk firmware.
  • C. Power cycle the disk shelf.
  • D. Unfail the disk

Answer: A,D

Explanation:
If a disk is marked as failed, the Failure Byte on the disk indicates that the disk has been flagged for failure.
This can be cleared using the following methods:
* What it does:Physically remove the disk from the shelf and reseat it. This action can trigger the system to re-evaluate the disk's status and clear the Failure Byte if the failure was transient or due to connection issues.
1. Reseat the Disk
* What it does:Using the disk unfail command in maintenance mode clears the Failure Byte and returns the disk to service.
* Command Example:
2. Unfail the Diskdisk unfail <disk_name>
* A. Power cycle the disk shelf:
* Power cycling the shelf may clear other transient hardware issues but does not specifically clear the Failure Byte.
* C. Update the disk firmware:
* While updating firmware can prevent future issues, it does not address disks already marked as failed.
Why Other Options Are Incorrect:
* NetApp "Disk Maintenance Guide" explains procedures to address failed disks.
* The "ONTAP Command Reference" covers the disk unfail command for clearing the Failure Byte.

NEW QUESTION # 55
What should be the first step taken after detecting a NetApp WAFL inconsistency?

  • A. Stabilize the system.
  • B. Force offline the affected aggregate.
  • C. Run wafliron.
  • D. Run a dump to null.

Answer: A

Explanation:
When a WAFL inconsistency is detected, the first step is to stabilize the system before attempting any repairs or recovery.
* Stabilize the System:
* Ensure that the system is not experiencing ongoing hardware or software issues.
* Avoid making changes to the affected aggregate or volume until the system is stable.
* Assess the Impact:
* Determine which aggregates or volumes are affected and the severity of the inconsistency.
Steps to Handle WAFL Inconsistency:
* A. Run wafliron:
* Running wafliron should only be done after stabilizing the system and under guidance from NetApp Support.
* C. Force offline the affected aggregate:
* Forcing an aggregate offline without proper assessment can lead to data loss.
* D. Run a dump to null:
* Dumping data is not relevant for resolving a WAFL inconsistency.
Why Other Options Are Incorrect:
* "NetApp WAFL Troubleshooting Guide" specifies that stabilization is the first step after detecting inconsistencies.
* NetApp Support documentation provides guidelines for handling WAFL inconsistencies safely.

NEW QUESTION # 56
Which two of the following are field replaceable units (FRUs) on an AFF A220 system? (Choose two.)

  • A. NVMEM battery
  • B. chassis fan
  • C. mSATA boot device
  • D. NVME Flash Cache feature

Answer: A,C

Explanation:
* A. NVMEM battery
* Explanation:The NVMEM (Non-Volatile Memory) battery is a critical component for retaining data in case of a power failure. It is classified as a Field Replaceable Unit (FRU) in an AFF A220 system.
* Replacement Notes:
* Replacement can be performed by field engineers.
* The system will typically alert you when the battery requires replacement.
* B. mSATA boot device
* Explanation:The mSATA (mini-SATA) boot device contains the ONTAP operating system and is also a FRU in the AFF A220. It is critical for the system's boot process and can be replaced if it becomes faulty.
* Replacement Notes:
* Boot devices are easily replaceable while ensuring ONTAP is reinstalled on the new device.
Why the Other Options Are Incorrect:
* C. NVMe Flash Cache feature:
* Incorrect. NVMe Flash Cache is not a physical FRU but a feature for accelerating read performance. It is implemented via software and NVMe-based SSDs, which are not specifically field replaceable in AFF A220.
* D. Chassis fan:
* Incorrect. The AFF A220 does not classify chassis fans as FRUs. These are usually part of the cooling system, but their replacement may require system shutdown or is integrated into the design.
References:
* NetApp Hardware Documentation: AFF A220 Component Replacement Guide.
* NetApp Knowledge Base: Articles on replacing NVMEM batteries and mSATA boot devices.


NEW QUESTION # 57
An aggregate has experienced a multiple disk failure due to a failing I/O module (IOM). The module has been replaced and the aggregate is still failed.
What step can be taken to recover the aggregate?

  • A. Unfail the drives from maintenance mode.
  • B. Use diskcopy from maintenance mode.
  • C. Run wafliron from the boot_menu.
  • D. Unfail the drives in the order that they failed from the clustershell

Answer: A

Explanation:
When an aggregate fails due to multiple disk failures caused by a faulty I/O module (IOM), the first step after replacing the faulty IOM is to manually unfail the affected drives. This process is done in maintenance mode.
* Enter Maintenance Mode:
* Reboot the node and interrupt the boot process to access maintenance mode.
* Identify Failed Drives:
* Use the command:
Steps to Recover the Aggregate:sql
Copy code
storage show disk -broken
This command lists all failed (broken) drives.
* Unfail the Drives:
* Use the following command for each failed drive:
php
Copy code
disk unfail <disk-name>
* Reconstruct the Aggregate:
* Once all drives are unfail, the system should begin reconstructing the RAID groups in the aggregate.
* A. Use diskcopy from maintenance mode:
* Diskcopy is used for cloning or copying data between disks, not for recovering failed aggregates.
* B. Run wafliron from the boot_menu:
* wafliron is used to repair WAFL inconsistencies, but it does not help recover failed aggregates due to disk issues.
* D. Unfail the drives in the order that they failed from the clustershell:
* Drives must be unfail in maintenance mode, not from the clustershell.
Why Other Options Are Incorrect:
* NetApp's "Aggregate and RAID Troubleshooting Guide" explains the process of recovering aggregates and using maintenance mode commands.
* "ONTAP Disk Recovery Guide" outlines steps to unfail disks and recover RAID groups.
