Hitachi NAS Platform 4000 Series - Powering on the Server or Cluster

When the system is properly shut down, depending on the battery charge level, the
battery may last up to one year without being char
ged or conditioned . See
NVRAM
backup battery pack (on page 38) for details.
Contact your r
epr
esentative for special instructions if servers or NVRAM battery backup
packs will be in storage for more than one year. Special provisions are required for eld
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 o.
Note: The PSUs continue to run, and the PSU LEDs stay on.
3. Po
wer down the server by removing the power cables from the PSU modules.
4. W
ait 10-15 seconds, then check that the NVRAM Status LED on the rear panel of the
server is o.
■ If the NVRAM status LED is o, 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 ashing), pr
ess and hold the
r
eset button for ve seconds until the NVRAM Status LED begins to ash r
apidly.
Release the reset button to disable the battery. The NVRAM Status LED goes out.
Note: The NVRAM contents are lost. The battery is r
e-enabled when
power is restored to the server.
Powering on the server or cluster
T
o start/po
wer on a server or cluster:
Procedure
1. Verify that all servers are switched o.
2. Start all stor
age subsystems, beginning with the e
xpansion 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 rst,
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.
