The following workflow describes the Fast Snap pair status changes:
1. You choose two volumes that are in SMPL status and are not in use as a Fast Snap pair.
2. You create a pair. If the primary volume has not previously been paired with any secondary volume,
the pair status changes to "COPY" at first, and then to "PAIR" after the pair creation finishes.
• Creation of a Fast Snap pair may be time consuming if you create a pair immediately after deleting
the last snapshot data for the primary volume.
• If the pool threshold is exceeded when the Fast Snap pair is in "PAIR" status, the pair status
changes to "PFUL."
• Fast Snap pairs cannot be created when the pool threshold (warning threshold when snapshot data
is stored in a THP pool) is exceeded.
3. Snapshot data is stored when you split a pair in "PAIR" status. After snapshot data is stored, the pair
status is "PSUS." If the pool threshold is exceeded when the Fast Snap pair is in "PSUS" status, the
pair status changes to "PFUS."
4. If you only want to delete snapshot data but do not want to release the Fast Snap pair, you delete the
snapshot data for the pair in "PSUS" or "PFUS" status.
