NEW QUESTION # 46
What should be the first step taken after detecting a NetApp WAFL inconsistency?

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

Answer: D

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 # 47
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. 0a and 0d on both controllers should be connected
C. 0c and 0d on both controllers should be connected.
D. 0a and 0c on both controllers should be connected.

Answer: D

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 # 48
Which two of the following methods are valid ways to access a node which is not booting? (Choose two.)

A. node management port
B. Service Processor
C. serial console
D. cluster management port

Answer: B,C

Explanation:
If a node is not booting, the following methods can be used to access the system for troubleshooting:
* What it does:The SP provides out-of-band management access to the node, even if the node is not booting.
* How to use:
* Connect to the SP using SSH or a direct console connection.
* Use SP commands to gather logs or perform diagnostics.
1. Service Processor (SP)
* What it does:The serial console provides direct access to the node's bootloader or maintenance mode.
* How to use:
* Connect to the serial port using a terminal emulator.
* Use console commands to interact with the system.
2. Serial Console
* A. node management port:
* The node management interface is only accessible if the node is booted and ONTAP is running.
* B. cluster management port:
* The cluster management interface requires the cluster to be operational, which is not possible if the node is not booting.
Why Other Options Are Incorrect:
* NetApp "Service Processor and Serial Console Guide" provides instructions for accessing a non- booting node.

NEW QUESTION # 49
Which two commands confirm whether an aggregate is WAFL inconsistent? (Choose two.)

A. storage aggregate show
B. node run -node <node> sysconfig -r
C. node run -node <node> sysconfig -a
D. wafiron show <aggregate>

Answer: B,D

Explanation:
To determine whether an aggregate is WAFL (Write Anywhere File Layout) inconsistent, the following two commands can be used:
* What it does:This command directly checks the WAFL consistency status of the specified aggregate. If an aggregate is WAFL inconsistent, it will report the inconsistency in the output.
* How to use:
* Run the command: wafiron show <aggregate> (replace <aggregate> with the name of the aggregate).
* Look for indications of WAFL inconsistency in the output.
* Why it's relevant:The wafiron utility is specifically designed to provide WAFL status and diagnostics.
It is the most accurate and direct way to confirm whether an aggregate is inconsistent.
* References:
* "WAFL Troubleshooting Guide" from NetApp highlights the wafiron show command as a primary tool for checking aggregate consistency.
1. wafiron show <aggregate>
* What it does:This command displays RAID information for all aggregates on the specified node. If an aggregate is WAFL inconsistent, it will be explicitly mentioned in the output.
* How to use:
* Run the command: node run -node <node> sysconfig -r.
* Check the output for the phrase "WAFL inconsistent" under the corresponding aggregate.
* Why it's relevant:This command provides additional context, such as the RAID group details, which can help understand whether the inconsistency is isolated or part of a larger issue.
* References:
* "ONTAP CLI Commands Guide" specifies sysconfig -r as a method to verify aggregate status, including WAFL consistency.
2. node run -node <node> sysconfig -r
* C. storage aggregate show:
* This command displays aggregate configuration and usage information but does not report WAFL inconsistency.
* D. node run -node <node> sysconfig -a:
* While this command shows detailed hardware configuration information, it does not include WAFL consistency status for aggregates.
Why Other Options Are Incorrect:
