3 Powering Off/On the Storage System

This chapter describes how to power the storage system on and off.

Powering Off the Storage System

NOTE: Power distribution units (PDU) in any expansion cabinets connected to the storage system
may need to be shut off. Use the locatesys command to identify all connected cabinets before
shutting down the system. The command blinks all node and drive enclosure LEDs.
Before you power off, use either SPmaint or SPOCC to shut down the system (see Service Processor
Onsite Customer Care in the HP 3PAR StoreServ 7000 and 7000c Storage Service Guide).
The system must be shut down before powering off by using any of the following three methods:
Using SPOCC
1. Select InServ Product Maintenance.
2. Select Halt an InServ cluster/node.
3. Follow the prompts to shutdown a cluster. Do not shut down individual nodes.
4. Turn off power to the node PCMs.
5. Turn off power to the drive enclosure PCMs.
6. Turn off all PDUs in the rack.
Using SPmaint
1. Select option 4 (InServ Product Maintenance).
2. Select Halt an InServ cluster/node.
3. Follow the prompts to shutdown a cluster. Do not shut down individual nodes.
4. Turn off power to the node PCMs.
5. Turn off power to the drive enclosure PCMs.
6. Turn off all PDUs in the rack.
Using CLI Directly on the Controller Node if the SP is Inaccessible
1. Enter the CLI command shutdownsys
2. Allow 2 to 3 minutes for the node to halt, then verify that the node Status LED is flashing green
and the node hotplug LED is blue, indicating that the node has been halted. For information
about LEDs status, see
CAUTION:
system to view the shutdown as uncontrolled and place the system in a checkld state upon
power up. This can seriously impact host access to data.
3. Turn off power to the node PCMs.
4. Turn off power to the drive enclosure PCMs.
5. Turn off power to all PDUs in the rack.

Powering On the Storage System

1. Set the circuit breakers on the PDUs to the ON position.
2. Set the switches on the power strips to the ON position.
3. Power on the drive enclosure PCMs.
