During which two operations is the NVRAM replayed by the high-availability (HA) partner?

Description:

When a negotiated takeover occurs (e.g., for maintenance or upgrades), NVRAM data is replayed by the HA partner to ensure no data is lost.

Relevance:

This ensures that all pending writes are safely processed by the partner node.

1. During a Negotiated Takeover:

Description:

If a node loses power unexpectedly, the HA partner replays the mirrored NVRAM data to protect active write operations.

2. When the Node Loses Power:

A. after triggering a sync core:

Triggering a sync core does not involve NVRAM replay; it captures the system state for debugging.

B. when a node is halted:

Halting a node does not trigger NVRAM replay unless it is part of a negotiated takeover.

Why Other Options Are Incorrect:

"ONTAP High Availability Guide" explains NVRAM mirroring and replay during failover scenarios.
