Failure during Thin Image pair restore
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.
