Network Appliance NetApp Accredited Hardware Support Engineer Sample Questions (Q17-Q22):

NEW QUESTION # 17
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 0c on both controllers should be connected.
  • B. 0a and 0d on both controllers should be connected
  • C. 0a and 0b on both controllers should be connected.
  • D. 0c and 0d on both controllers should be connected.

Answer: A

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 # 18
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. PCI-HIERARCHY.XML
  • B. ALL-COREDUMP.XML
  • C. HA-RASTRACE.TGZ
  • D. SSRAM-LOG

Answer: C,D

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


NEW QUESTION # 19
What is the default amount of time that a volume is available for recovery from the volume recovery queue following a volume deletion?

  • A. 72 hours
  • B. 48 hours
  • C. 12 hours
  • D. 24 hours

Answer: C

Explanation:
When a volume is deleted in a NetApp ONTAP system, it is placed in the Volume Recovery Queue. By default, the volume remains in this recovery queue for 12 hours before being permanently deleted. This allows administrators to recover mistakenly deleted volumes within the set retention period.
Explanation of Default Behavior:
* Volume Recovery Queue:
* This is a feature in NetApp ONTAP that acts as a safety mechanism, providing a grace period for recovering deleted volumes.
* The default retention period for volumes in the recovery queue is 12 hours, as confirmed by the NetApp KB: "How to use the Volume Recovery Queue."
* How to Recover a Deleted Volume:
* Administrators can recover a deleted volume as long as it remains in the recovery queue and the retention period has not expired.
* Use the ONTAP CLI command:
arduino
Copy code
cluster::> volume recovery-queue recover -vserver <vserver_name> -volume <volume_name>
* This command restores the volume back to its original state.
* How to Check the Volume Recovery Queue:
* To view volumes in the recovery queue and their expiration times, use:
arduino
Copy code
cluster::> volume recovery-queue show
* Changing the Default Retention Period:
* While the default period is 12 hours, it can be adjusted by administrators to fit specific organizational requirements. This is done via system settings or policies.
Why the Other Options Are Incorrect:
* B. 48 hours: Incorrect. The default retention period is not 48 hours; it is 12 hours by default.
* C. 72 hours: Incorrect. While a custom configuration could allow this, it is not the default.
* D. 24 hours: Incorrect. Although this was previously thought to be the default, NetApp documentation explicitly states it is 12 hours.
References:
* NetApp Knowledge Base Article: "How to use the Volume Recovery Queue".
* NetApp ONTAP Documentation: Volume Recovery and Data Management Procedures.


NEW QUESTION # 20
In maintenance mode, which of the following commands shows disk ownership?

  • A. aggr status
  • B. storage show disk -p
  • C. sysconfig -v
  • D. disk show -v

Answer: D

Explanation:
In maintenance mode, the command disk show -v provides detailed information about disk ownership. This includes the current owner, previous owner, and disk health status.
* Enter maintenance mode, and run:
How to Use:disk show -v
* The output will display ownership information for each disk, including its RAID group and current assignment.
* A. sysconfig -v:
* This command provides system configuration details but does not show disk ownership.
* C. aggr status:
* This command shows the status of aggregates, not individual disks or their ownership.
* D. storage show disk -p:
* This command is not valid in maintenance mode.
Why Other Options Are Incorrect:
* NetApp "Maintenance Mode Commands Guide" highlights disk show -v as the command to check disk ownership.
References:


NEW QUESTION # 21
After a panic, the customer asks you to explain the error "watchdog timeout." Which explanation would be appropriate?

  • A. An optional software that monitors system performance.
    An overloaded system fails to reset the watchdog and watchdog induces a system panic.
  • 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. A service that monitors network activity and protects data.
    A watchdog induces system panic to protect data if malicious activity is detected.

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.
