Just go to mydocs.emc.com You can generate those documents there. Just select Model and type (Unified) and it will generate PDFs for you for the power off and power-on procedures. Unisphere should have a Power Off option, then it can properly shut down everything. Power on order is: DAEs, then DPE, then Data Movers, then control station(s). The documents will show you what status to wait for until the next step. But what component do you need to replace that requires a complete shutdown?
Guys, I need to power down VNX 5300 unified completely. Replace the component and power back up.   Please share the procedure to power down the full storage and then power back up once ths task is completed.   Thank You
