Suggested answer: B, D

Explanation:

Understand Pre-Upgrade Health Check:

Purpose: The pre-upgrade health check is designed to ensure the system is in a stable state before proceeding with firmware or software upgrades. This helps to avoid disruptions and data loss.

Volumes on Non-Preferred Path (B):

Issue: If volumes are reported on a non-preferred path, it indicates that there might be a pathing issue or an imbalance in the I/O load.

Impact: Non-preferred paths can lead to performance degradation and increased latency, which might cause issues during the upgrade process.

Resolution: Ensure that all volumes are accessible through their preferred paths before initiating the upgrade.

I/O Being Processed (D):

Issue: Active I/O during the upgrade process can lead to incomplete or failed upgrades.

Impact: Processing I/O during an upgrade can result in data corruption or loss, and may also cause the upgrade to fail.

Resolution: Suspend or stop all I/O operations on the system before starting the upgrade.
