Procedure: Powering on the Storwize V7000 Gen2 system

After installing all hardware components, you must power on the Storwize V7000
Gen2 system and check its status.
About this task
Attention: Do not power on the system with any open bays or slots.
v Every unused drive bay must be occupied by a filler panel.
v Filler plates must be installed in all empty host interface adapter slots.
Open bays or slots disrupt the internal air flow, causing the drives to receive
insufficient cooling.
Procedure
To power on the system, complete the following steps.
1. Power on the control enclosure by connecting both power supply units of the
enclosure to their power sources, using the supplied power cables. If the power
sources have circuit breakers or switches, ensure that they are turned on. The
enclosure does not have power switches.
Note: Each enclosure has two power supply units. To provide power failure
redundancy, connect the two power cords to separate power circuits.
2. Check the LEDs on each node canister in the control enclosure, as displayed in
Figure 77.
Figure 77. Node canister LEDs
1 Power
2 Status
3 Fault
The canister is ready with no critical errors when Power is illuminated, Status
is blinking, and Fault is off. If a canister is not ready, refer to the "Procedure:
Understanding the system status using the LEDs" topic in the troubleshooting
section of the Storwize V7000 Unified information center.
Procedure: Powering off a Storwize V7000 Gen2 control
enclosure
To service a Storwize V7000 Gen2 control enclosure, you must safely power off
both of the node canisters in the enclosure.
Before you begin
Host connectivity for hosts that are connected to the control enclosure is lost when
the control enclosure is shut down. You must quiesce I/O activity of these hosts
before doing this procedure.
About this task
If your system has a single control enclosure, complete the steps in "Procedure:
Powering off your system" on page 280 instead of following this procedure. Doing
so provides a more coordinated shutdown of the whole system.
