If a
Lenovo Storage V7000 Gen2 control enclosure has been shut down with the GUI or CLI, you must
restart it by reseating the node canisters.
Note: If enclosure input
power was removed from both power supply units, the input power LED
of both PSUs is off. To restart the enclosure in this case, refer
to "Procedure: Powering on the Lenovo Storage V7000 Gen2 system".
