Latest NetApp NS0-093 Practice Questions BY Rojas

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:

1. Reseat the Disk

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.

2. Unfail 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:

disk unfail <disk_name>

Why Other Options Are Incorrect:

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.

NetApp 'Disk Maintenance Guide' explains procedures to address failed disks.

The 'ONTAP Command Reference' covers the disk unfail command for clearing the Failure Byte.
