NetApp Certified Support Engineer (NCSE) – ONTAP — Question 23

You have replaced a failed boot device. You perform boot_recovery and receive no errors. However, when the node reboots, it reports that it has no disks.
What are two possible causes? (Choose two.)

Answer options

• A. The SAS cables were incorrectly reconnected after reinstalling the motherboard.
• B. The disks that are owned by this node have been marked as failed.
• C. The node is booting a lower version of ONTAP software than was last used.
• D. The interconnect is down.

Correct answer: A, B

Explanation

The correct answers are A and B because if the SAS cables are not connected properly, the node will not detect the disks. Additionally, if the disks are marked as failed, they will not be recognized by the system. Options C and D are less likely causes in this scenario, as they do not directly relate to the node's ability to detect installed disks after a boot recovery.
