Maintaining pairs during storage system maintenance
Switching off the power supply
1. Stop the host I/O.
2. Switch off the power supply.
When power is restored, the behavior of Fast Snap depends on the following:
• The power supply and having data in shared memory.
• The power supply and losing data in shared memory.

Power supply and existing shared memory
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:
1. Restore the power.
2. Recover the pools.
