Powering off disk enclosures
CAUTION:
Be sure that the server controller is the first unit to be powered down and the last to
be powered back up. Taking this precaution ensures that the system does not erroneously mark
the disk drives as failed when the server is later restarted. It is recommended to perform this action
with P6000 Command View (see below).
IMPORTANT:
If installing a hot-plug device, it is not necessary to power down the enclosure.
To power off a disk enclosure:
1.
Power down any attached servers. See the server documentation.
2.
Perform an orderly shutdown of the array controllers.
3.
Allow all components to enter standby power mode. Note that not all indicators may be off.
4.
Disconnect the power cords
The system is now powered down.
Shutting down the storage system from HP P6000 Command View
1.
Start HP P6000 Command View.
2.
Select the appropriate storage system in the Navigation pane.
The Initialized Storage System Properties window for the selected storage system opens.
3.
Click Shut down.
The Shutdown Options window opens.
4.
Under System Shutdown click Power Down. If you want to delay the initiation of the shutdown,
enter the number of minutes in the Shutdown delay field.
The controllers complete an orderly shutdown and then power off. The disk enclosures then
power off. Wait for the shutdown to complete.
5.
Turn off the power to the rack power distribution units. Even though the disk enclosures are
powered off in
, unless the power on the rack distribution units are turned off, the I/O
modules remain powered on in a standby state.
Shutting down the storage system from the array controller
CAUTION:
Use this power off method for emergency shutdown only. This is not an orderly
shutdown and cached data could be lost.
1.

callout 9 in
).
2.
Wait 4 seconds. The power button and the green LED start to blink.
NOTE:
Use this power off method for emergency shutdown only. This is not an orderly
shutdown and cached data could be lost.
3.
After 10 seconds, the power shuts down.
Starting the storage system
To start a storage system, perform the following steps:
1.
Turn on the SAN switches and wait for all switches to complete the power-on boot process.
It may be necessary to wait several minutes for this to complete.
NOTE:
Before applying power to the rack PDUs, ensure that the power switch on the controller
enclosure is off.
