A new feature with the release of VNX Rockies(Block OE 5.33 & File OE 8.1) was the ability to Shutdown the Entire Array using either a single command or via the ‘Power Off’ button in the Unisphere GUI. This feature is also available for first generation VNX storage system’s, from VNX OE code release 05.32.000.5.209 & 18.104.22.168 onwards.
These options are supported on Unified, Block and File systems.

The new CLI option extends the nas_halt command to include a new switch to power down the entire system :
nas_halt –f –sp now
This will power off Control Stations, Data Movers and the Storage Processors.
usage: nas_halt [-f] [-sp] now
Perform a controlled halt of the Control Station(s) and Data Mover(s)
