Which of the following statements is true about giveback with storage failover?
The correct answer is C. The surviving partner returns ownership of the root aggregate first followed by the other. During storage failover giveback, aggregate ownership is returned in a specific sequence to ensure the recovered node initializes correctly before data access resumes.

- BThe surviving partner returns ownership of the all the aggregates and the data LIFS to its partner
- CThe surviving partner returns ownership of the root aggregate first followed by the other
- DI/O only resumes when all aggregates are returned to the partner node

Why each option
During storage failover giveback, aggregate ownership is returned in a specific sequence to ensure the recovered node initializes correctly before data access resumes.
Aggregates are not returned simultaneously; the root aggregate must be returned first to allow the node to reach an operational state before data aggregate ownership transfers.
Data LIFs are not part of the aggregate giveback sequence; LIF migration is a separate process that ONTAP manages independently of aggregate ownership transfers.
The giveback process returns the root aggregate first so the recovered node can boot and initialize its ONTAP operating environment. Once the root aggregate is online, data aggregates are returned sequentially, allowing I/O to resume on a per-aggregate basis rather than waiting for a full batch return.
I/O resumes on a per-aggregate basis as each aggregate is given back, so clients can access data progressively rather than waiting for all aggregates to be returned.
