- For an aggregate, all FlexVol volumes must be mounted before data can be served from any of the FlexVol volumes in the aggregate.
- If the aggregate contains a FlexVol volume with LUNs, then all LUNs within that FlexVol volume must complete their Phase 1 checks before any LUN in that FlexVol volume can be brought online.
- Verifies file system access by checking the necessary metadata. This includes checks of the aggregate metadata associated with each FlexVol volume contained in that aggregate, metadata tracking free space, and Snapshot copy sanity.
- Phase 1 will check the aggregate first and then each FlexVol volume on that aggregate. After all FlexVol volumes within the aggregate are checked, the aggregate and FlexVol volumes will be mounted.
