Power supply and losing data in shared memory
If you lose power and the data in shared memory is lost, the VSP G1000 storage system saves the data to SSD at the time the power supply is switched off, but for VSP G200, G400, G600, G800, you must recreate the pools and pairs.
You can still use the pool and Thin Image pairs with a VSP G1000 storage system, because the data is restored to shared memory from SSD after switching the power supply back on.
For a VSP G200, G400, G600, G800 storage system, first restore the power, then recreate the pools and pairs.
