When you switch off the power supply, data in the shared memory is usually saved to SSD. Then, when you switch the power supply back on, the data is restored to shared memory from SSD, so you can continue to use the pools and Thin Image pairs.
When you switch on the power supply, the storage system checks the status of the pool and pool-VOLs. If the pool-VOLs are blocked, the pool is blocked and the pairs are suspended ("PSUE" status). In this case, you need to restore the pool after the power supply is switched on.
If you interrupt the workflow of storing snapshot data by consistency groups by switching off the power supply and the status of all the pairs in a consistency group has not completely changed, the workflow does not resume when you switch the power supply on again. If the status of some pairs remain unchanged, delete and re-create the pairs or delete snapshot data, and then store snapshot data by consistency groups again.
