• If the NVRAM status LED is off, the battery backup pack no longer
powers the NVRAM, so that the battery does not drain.
Note: Use this state for server storage or shipment.
• If the NVRAM status LED is on (either on steady or flashing), press
and hold the reset button for five seconds until the NVRAM Status LED
begins to flash rapidly. Release the reset button to disable the battery.
The NVRAM Status LED goes out.
Note: The NVRAM contents are lost. The battery is re-enabled when
power is restored to the server.
Verify that all servers are switched off.
Start all storage subsystems, beginning with the expansion enclosures.
Wait until the disk LEDs on all of the expansion enclosures have stopped
blinking (which indicates that they are spinning up) or two minutes,
whichever comes first, then start the storage subsystem RAID controller
enclosures. Note that the disk drives in some storage enclosures will not
spin up until commanded to do so by the RAID controller, so the LEDs
may continue to blink until after the RAID controller enclosure has sent
those commands and the drives have spun up.
For a cluster configuration, or when using an external System
Management Unit (SMU), start the SMU by depressing the red button
located on the right of the unit.
Wait one minute to allow the external SMU to start.
Power up the server or the first node in the cluster:
a. If the power cables are not connected to the PSU, plug in the power
cables.
b. If, after 10 seconds, the PSU LEDs are lit but the Power Status LED on
the rear panel is not lit, press the PWR button on the MFB to restore
the power to the system boards. Report this as a problem to the
Hitachi Data Systems Support Center.
c. If the power cables are connected to the PSU, press the PWR (power)
button on the rear of the server.
If you are starting a cluster, wait 5-10 seconds before powering on the
next node in the cluster.
Rebooting, shutting down, and powering off
