Powering On The Server Or Cluster - Hitachi NAS Platform 4000 Series Hardware Reference Manual

When the system is properly shut down, depending on the battery charge level, the
battery may last up to one year without being charged or conditioned . See
backup battery pack (on page 38)
Contact your representative for special instructions if servers or NVRAM battery backup
packs will be in storage for more than one year. Special provisions are required for field
or factory recharging and retesting of NVRAM battery backup packs.
Procedure
1. From the NAS operating system (Bali) console, issue the command: shutdown –-
ship --powerdown
2. Wait until the console displays the message Information: Server has shut
down and the rear panel LEDs turn off.
3. Power down the server by removing the power cables from the PSU modules.
4. Wait 10-15 seconds, then check that the NVRAM Status LED on the rear panel of the
server is off.
If the NVRAM status LED is off, the battery backup pack no longer powers the
■
NVRAM, so that the battery does not drain.
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.

Powering on the server or cluster

To start/power on a server or cluster:
Procedure
1. Verify that all servers are switched off.
2. 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 details.
Note: The PSUs continue to run, and the PSU LEDs stay on.
Note: Use this state for server storage or shipment.
Note: The NVRAM contents are lost. The battery is re-enabled when
power is restored to the server.
