Notes On The Wake On Lan (Wol) Functionality - Hitachi Compute Blade 2000 User Manual

Notes on the Wake On LAN (WOL)
functionality
1 Enable the WOL functionality before you use power control via WOL in
ServerConductor/Deployment Manager or ServerConductor/Blade Server
Manager.
WOL is supported only by the server blade's on-

board local area network (LAN) controller. WOL
is not supported by the server blade's expansion
card or expansion adapter.
If you are using the LAN driver (igb) included as

standard in Red Hat Enterprise Linux 5.x, WOL
using port 1 of the server blade's on-board LAN
controller is not supported.
By using the LAN driver (igb) provided by Hitachi,
WOL can be used from port 1 of the on-board
LAN controller, even in a Red Hat Enterprise
Linux 5.x environment.
By executing the following command, you can
check whether the Hitachi LAN driver (igb) has
been applied:
# modinfo igb | grep version
version: xx.xx.xx-hx
If "-hx" (where x is a number) appears at the end
of the "version:" value, the Hitachi LAN driver
(igb) has been applied.
When you use Windows Server 2012 R2 on a

high-performance server blade, WOL function is
not supported.
2 WOL is not enabled immediately after a server blade's AC power is turned on.
To enable WOL on a server blade, enable the WOL setting on the OS
supporting the advanced configuration and power interface (ACPI), and then
shut down the OS. (WOL is enabled immediately after the OS shuts down.)
Note that WOL is disabled by the following:
(1) Turning off the AC power on the server chassis
(2) Inserting or removing a server blade
(3) A power outage
(4) Forcibly powering off the server blades and chassis (Power Button
Override)
The server blade and chassis are forcibly powered off by holding down the
power button for at least four seconds. WOL is also disabled by the
following forced power-off methods: (1) the Management Module's "PC
Command"; (2) remote power control provided through the server blade
