3 Powering Off/On the Storage System The following describes how to power the storage system on and off. Powering Off NOTE: PDUs 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 begin, use either SPMAINT or SPOCC to shut down and power off the system (see section Service Processor Onsite Customer Care in the HP 3PAR StoreServ 7450 Storage Service Guide). The system can be shutdown before powering off by any of the following three methods: Using SPOCC 1. Select InServ Product Maintenenace. 2. Select Halt an InServ cluster/node. 3. Follow the prompts to shutdown an 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 an Inserv Cluster Do not shut down individual Nodes. NOTE: The shutdown procedure must be repeated for each node in the system. 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 - halt. Confirm all prompts. 2. Allow 2-3 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 "Understanding LED Indicator Status" (page 12). CAUTION: Failure to wait until all controller nodes are in a halted state could cause the 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 1. Set the circuit breakers on the PDUs to the ON position. 2. Set the switches on the power strips to the ON position. Powering Off 25

3 Powering Off/On the Storage System
The following describes how to power the storage system on and off.
Powering Off
NOTE:
PDUs 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 begin, use either SPMAINT or SPOCC to shut down and power off the system (see
section
Service Processor Onsite Customer Care
in the
HP 3PAR StoreServ 7450 Storage Service
Guide
).
The system can be shutdown before powering off by any of the following three methods:
Using SPOCC
1.
Select
InServ Product Maintenenace
.
2.
Select
Halt an InServ cluster/node
.
3.
Follow the prompts to shutdown an 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 an Inserv Cluster Do not shut down individual Nodes.
NOTE:
The shutdown procedure must be repeated for each node in the system.
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
–
halt
. Confirm all prompts.
2.
Allow 2-3 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
“Understanding LED Indicator Status” (page 12)
.
CAUTION:
Failure to wait until all controller nodes are in a halted state could cause the
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
1.
Set the circuit breakers on the PDUs to the ON position.
2.
Set the switches on the power strips to the ON position.
Powering Off
