Network Appliance NetApp Accredited Hardware Support Engineer Sample Questions (Q36-Q41):

NEW QUESTION # 36
What are two options to remove Failure Byte on disks that are marked as failed? (Choose two.)

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

Answer: B,C

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 # 37
Which two steps are required to replace a drawer in a DS460c shelf? (Choose two.)

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

Answer: B,C

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.

NEW QUESTION # 38
Your customer notices that their AFF A220 high-availability (HA) system is showing Single-Path HA.

How do you make the system into multipath HA?

  • A. 0a and 0b on both controllers should be connected.
  • B. 0c and 0d on both controllers should be connected.
  • C. 0a and 0c on both controllers should be connected.
  • D. 0a and 0d on both controllers should be connected

Answer: C

Explanation:
In a NetApp high-availability (HA) configuration, multipath HA ensures redundancy by providing two independent paths from each controller to the connected storage. If the system is currently showing Single- Path HA, it means only one path is operational or connected, which is a potential single point of failure.
To convert the configuration to multipath HA, additional cabling must be configured to establish the second path. For the AFF A220 system, the correct connections are as follows:
Explanation of the Correct answer:
* AFF A220 Port Configuration for HA:
* Each controller in an AFF A220 has ports labeled 0a, 0b, 0c, and 0d for connectivity.
* In a multipath HA configuration, each controller must have two independent paths to the connected storage via the partner controller's disk shelves.
* Correct Cabling for Multipath HA:
* Port 0a on both controllers must be connected to the corresponding port (e.g., disk shelf stack or Inter-Switch Link).
* Port 0c on both controllers must also be connected to complete the redundant path.
* These connections ensure that there are two independent data paths between the controllers and the storage system, providing fault tolerance in case one path fails.
* Single-Path HA to Multipath HA:
* If the system currently shows Single-Path HA, it is likely that only one set of ports (e.g., 0a and
0b) are cabled.
* Adding the additional connections on 0a and 0c establishes the second path required for multipath HA.
Why the Other Options Are Incorrect:
* A. 0a and 0b on both controllers should be connected:
* This option only connects ports 0a and 0b, which does not establish a multipath HA configuration. Port 0c is also required for redundancy.
* C. 0c and 0d on both controllers should be connected:
* Connecting only 0c and 0d would leave ports 0a disconnected, failing to establish a proper multipath HA setup. Both 0a and 0c are required.
* D. 0a and 0d on both controllers should be connected:
* Connecting 0a and 0d is not the standard configuration for multipath HA in an AFF A220 system. Port 0c is part of the required configuration.
How to Verify the Configuration:
* Use the following ONTAP command to verify the HA status:
cluster::> storage failover show -fields multipath-ha
* This will display whether the system is in multipath HA or single-path HA mode.
* Check the port connectivity:
cluster::> network port show -node <node_name>
References:
* NetApp Hardware Installation and Setup Guide for AFF A220.
* NetApp Knowledge Base: "Configuring Multipath HA for AFF Systems."
* ONTAP 9.x System Administration Guide: "High Availability Configurations." Understanding Single-Path HA vs. Multipath HA:
* Single-Path HA indicates that only one path exists between the controllers and the connected shelves, leading to limited redundancy.
* Multipath HA requires both controllers to have redundant SAS connections to the shelves.
Cabling for Multipath HA in AFF A220 Systems:
* To achieve multipath HA, you must connect 0c and 0d on both controllers to the appropriate stack ports on the shelves.
* This ensures dual paths for each controller to access the storage shelves.
NetApp Reference Documentation:
* Refer to the "ONTAP Multipath HA Configuration Guide" and the "NetApp Hardware Installation Guide" for AFF A220 systems for cabling diagrams and best practices.


NEW QUESTION # 39
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 does not have an owner.
  • B. The disk is failed.
  • C. The disk is in the maintenance center.
  • D. The disk is not owned by a member of the high-availability (HA) pair.

Answer: A

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 # 40
After a panic, the customer asks you to explain the error "watchdog timeout." Which explanation would be appropriate?

  • A. A service that monitors network activity and protects data.
    A watchdog induces system panic to protect data if malicious activity is detected.
  • B. An optional component included with Active IQ Unified Manager.
    It notifies a user if watchdog fails to reach the storage system within a certain period.
  • C. A service that detects and recovers from computer malfunctions.
    A hardware or software error prevents update of watchdog and it induces a system panic.
  • D. An optional software that monitors system performance.
    An overloaded system fails to reset the watchdog and watchdog induces a system panic.

Answer: C

Explanation:
What Is a Watchdog Timeout?
* The watchdog is a software or hardware mechanism that monitors the system's health and ensures it is operating correctly.
* If the system fails to respond or update the watchdog timer within the specified time, the watchdog triggers a system panic to avoid further corruption or damage.
Cause of Watchdog Timeout:
* This usually occurs due to:
* A hardware failure (e.g., CPU or memory issue).
* A software bug causing a system hang or crash.
* The panic ensures the system stops operation to preserve data integrity and aid in troubleshooting.
NetApp Reference Documentation:
* "ONTAP Troubleshooting Guide" and "Core Dump Analysis Guide" provide details on interpreting watchdog timeouts and recommended actions.
