NS0-093 Dumps With Exact Questions and Answers

When a node fails to boot and loads the previous version of ONTAP, it usually indicates that the primary boot location is incorrect. To resolve this:

Enter the LOADER Prompt:

Interrupt the boot process to access the LOADER prompt.

Set the Primary Kernel URL:

Use the following command:

Steps to Boot the Correct ONTAP Version:setenv GX_PRIMARY_KERNEL_URL

Boot the Node:

Run the boot command to load the correct version.

B. From the loader prompt of nodeA1, run boot_backup:

Booting the backup image may result in an outdated version of ONTAP, not the desired version.

C. From the clustershell of the partner, run system node image modify:

Modifications to the ONTAP image must be done from the LOADER prompt, not the clustershell.

D. From the clustershell of nodeA1, run system node image modify:

NodeA1 cannot load ONTAP, so this command cannot be run.

Why Other Options Are Incorrect:

"ONTAP System Boot Guide" explains how to resolve boot issues using the LOADER prompt.

NetApp documentation on environment variables includes the use of GX_PRIMARY_KERNEL_URL.

References:

The Upgrade Advisor is a NetApp tool that generates a detailed, step-by-step plan for upgrading an ONTAP system. This tool is available through the Active IQ portal and helps ensure a smooth and risk-free upgrade process.

Provides a tailored upgrade plan based on the current ONTAP version, cluster configuration, and desired target version.

Identifies potential risks, compatibility issues, and pre-requisite tasks for the upgrade.

Offers detailed instructions for each stage of the upgrade process.

Key Features of Upgrade Advisor:

A. ONTAP System Manager:

While System Manager can be used to initiate upgrades, it does not generate a detailed upgrade plan.

B. Active IQ Unified Manager:

Unified Manager focuses on monitoring and management but does not provide upgrade plans.

D. Active IQ Config Advisor:

Config Advisor checks for best practices and configuration issues but is not used for generating upgrade plans.

Why Other Options Are Incorrect:

NetApp’s "ONTAP Upgrade Guide" emphasizes the use of Upgrade Advisor for planning upgrades.

Active IQ documentation provides detailed instructions on accessing and using the Upgrade Advisor tool.

Reverting to a previous ONTAP version requires careful preparation because ONTAP upgrades often introduce irreversible changes. To successfully revert, the following actions are needed:

C. Reinstall your boot media and install ONTAP 9.5 software

Explanation:You need to reinstall the older version of ONTAP (9.5) on the boot media because the current version (9.7) has been installed as part of the upgrade. The reinstallation ensures that the system boots with ONTAP 9.5.

Steps:

Boot the node into maintenance mode.

Perform the reinstallation using the appropriate ONTAP 9.5 image.

D. Wipe your config and restore from backup

Explanation:A revert requires wiping the configuration because ONTAP upgrades may have made changes to the cluster configuration or WAFL metadata. Restoring the configuration from a backup ensures consistency with the older ONTAP version.

Steps:

Back up the current cluster configuration before proceeding.

Use the restored backup after the revert is complete to reconfigure the system.

Why the Other Options Are Incorrect:

A. Revert from ONTAP 9.7 software to ONTAP 9.6 software and then to ONTAP 9.5 software:

Incorrect. ONTAP reverts must directly target the desired version. You cannot perform multi-step reverts.

B. Delete all Snapshot copies from the past two days:

Incorrect. Deleting Snapshot copies is not a prerequisite for reverting ONTAP. While older Snapshot copies might not be compatible with the reverted version, they do not need to be deleted before the revert.
