If a failure occurs while restoring Thin Image pairs, the pairs are suspended.
During a failure, the storage system does the following:
- Blocks and suspends the Thin Image pair ("PSUE" status), including pairs that have snapshot data in the pool.
- Writes data to the Thin Image pair volumes.
- Exceeds the data pool capacity of snapshot data.
If a failure occurs, delete the unneeded snapshot data by restoring the suspended pairs.
