Netapp NS0-093 Dumps Questions Answers

To confirm the successful completion of an ONTAP upgrade, the cluster image show-update-progress command provides the necessary details.

Command:

Key Command:cluster image show-update-progress

Displays the status of the cluster upgrade, including which nodes have successfully upgraded and whether the process has completed.

A. system controller sp upgrade show:

This command displays information about SP (Service Processor) firmware upgrades, not ONTAP upgrades.

C. job show –jobtype upgrade:

While this command shows upgrade jobs, it does not confirm the completion of the cluster-wide ONTAP upgrade.

D. system node upgrade-revert upgrade-task –node <nodename> –version <ontap Version>:

This command reverts an upgrade task, not confirms completion.

Why Other Options Are Incorrect:

NetApp "ONTAP Upgrade Guide" specifies the cluster image show-update-progress command as the primary method to verify upgrade completion.

If the root volume runs out of space, it can cause operational issues and require recovery.

The root volume must always have sufficient space for system logs, configuration files, and core dumps.

1. Root Volume Ran Out of Space:

When a mainboard is replaced, the system configuration stored in the root volume may need to be restored or recovered.

2. Mainboard Was Replaced Following an NMI Panic:

C. Root volume migrate was performed:

Root volume migration is a normal operation and does not typically cause the need for root volume recovery.

D. The cluster configuration is out of sync on the volume:

While this can cause configuration issues, it does not directly lead to root volume recovery.

Why Other Options Are Incorrect:

"ONTAP Root Volume Management Guide" explains scenarios leading to root volume issues and recovery procedures.

When using wafliron to repair WAFL inconsistencies on an aggregate, the aggregate becomes available after Phase 4 of the wafliron process is complete.

Phase 1: Initial scan to identify inconsistencies.

Phase 2: Corrects directory and inode structure issues.

Phase 3: Repairs blocks and metadata.

Phase 4: Completes final repairs and verification, after which the aggregate can be made available.

Phases of wafliron:

A. when the administrator manually onlines the aggregate:

The aggregate cannot be manually brought online until wafliron completes Phase 4.

B. when wafliron is started:

Starting wafliron does not make the aggregate available; repairs need to be completed first.

D. after the mounting phase of wafliron is complete:

WAFLiron does not have a specific "mounting phase." Mounting happens after Phase 4 completes.

Why Other Options Are Incorrect:

"NetApp WAFLiron Troubleshooting Guide" explains the availability of the aggregate after Phase 4.

NetApp Support documentation outlines the phases of wafliron and aggregate recovery.
