EMC VNXe 3100 Power Button

Just in case you also get caught by this, this particular storage array does not have a power button. Instead, once power is cycled (unplug the cords and replug), it will boot up and run internal diagnostics prior to powering back up. It took about 15-20 minutes for it come online again after it was safely shutdown.

If you have other hosts/services that depend on it to be online first, it is probably a good idea to wait for the array to come online first before powering them on, otherwise you’ll have to restart any services that depend on it.
