Power supply and losing data in shared memory
If you lose power and the data in shared memory is lost, the VSP G1x00 and VSP F1500 storage systems save the data to SSD at the time the power supply is switched off, but for VSP Gx00 models and VSP Fx00 models, you must recreate the pools and pairs.
You can still use the pool and Thin Image pairs with a VSP G1x00 or VSP F1500 storage system, because the data is restored to shared memory from SSD after switching the power supply back on.
For VSP Gx00 models and VSP Fx00 models, first restore the power, then recreate the pools and pairs.
