12.10.2 Shutting down and starting up the infrastructure
To shut down an entire infrastructure (storage, servers, and applications), complete the
following steps:
1. Power off your servers and all applications.
2. Power off your IBM Storwize V5000 Gen2 system by using either the GUI or the CLI.
3. Remove the power cords that are connected to both power supplies in the rear of the
enclosure on every control and expansion enclosure.
4. Power off your storage area network (SAN) switches.
To start an entire infrastructure, complete the following steps:
1. Power on your SAN switches and wait until the boot completes.
2. Power on any expansion enclosures by connecting the power cord to both power supplies
in the rear of the enclosure or by turning on the power circuit.
3. Power on the control enclosures by connecting the power cords to both power supplies in
the rear of the enclosure and by turning on the power circuits.
The system starts. The system starts successfully when the status LEDs of all node
canisters in the control enclosure are permanently on, which takes no longer than 10
minutes.
Power on your servers and start all applications.
Note: When you power off an IBM Storwize V5000 Gen2, it does not automatically
restart. You must manually restart the system by removing and reapplying the power /
power cords.
