7 Power Off/On the Storage System
The following describes the procedures for powering off and on the storage system.
Powering Off the Storage System
When it is necessary to power off the storage system, use the following steps to safely remove
power from the storage system and the SP.
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. locatesys will blink all
node and drive cage LEDs. Note this information now, as it is needed for the last step in this
procedure.
To power off the storage system:
1. Connect the maintenance PC to the SP using the serial connection. Refer to the “Connecting
the Maintenance PC” chapter in the appropriate HP 3PAR Storage System Maintenance
Manual.
2. Start an spmaint session.
NOTE: If using SPOCC, on the SPOCC homepage, click Support > SPMAINT on the Web
> InServ Product Maintenance > Halt an InServ cluster/node and skip to step 7.
3. In the 3PAR Service Processor Menu, select option 4, InServ Product Maintenance.
4. Select option 6, Halt an InServ cluster/node.
5. Select the desired system and confirm all prompts to halt the system.
6. Press x to return to the 3PAR Service Processor Menu.
CAUTION: Failure to wait until all controller nodes are in a halted state as defined in Step
7could 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.
7. Allow 2-3 minutes for the system to halt, then verify the node status LEDs are flashing green
(at a rate of three blinks per second) and the node hot-plug LEDs are solid amber (for the
StoreServ 10000 Storage, the node service LED is blue) which indicate the nodes have halted.
For more information see the LED chapters in this manual.
8. Select option 1, SP Control/Status.
9. Select option 3, Halt SP.
10. When prompted, press Y to confirm halting the SP.
11. Wait approximately 30 seconds and verify if the LED on the front of the SP is no longer
illuminated.
12. Remove AC to the storage system by turning off all of the PDU circuit breakers in the cabinet.
13. If necessary, replace the bezel and close and lock the rear door.
Powering On the Storage System
NOTE: The system takes approximately 10-15 minutes to become fully operational providing it
was gracefully shut down. If the system was powered off abruptly, powering on could take
considerably longer.
If the TOC is over a day old, it is considered invalid, and the setsysmgr tocgen command
must be issued to select the appropriate TOC. Refer to the HP 3PAR OS CLI Reference for more
information.
