After you switch off the power supply, you can use the pools and pairs if data in the shared memory exists and the data is not blocked.
The storage system checks the status of the pool and pool-VOLs. If the pool-VOLs are blocked at the time you switch off the power supply, the pool is blocked and the pairs are suspended ("PSUE" status).
If you interrupt the workflow of storing snapshot data or cloning pairs 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. The status of some pairs may remain unchanged.
If the pool is blocked and the pairs are suspended, complete the following:
- Restore the power.
- Recover the pools.
