Administrator's Guide

Restrictions
• <bay#> must be 1 or 2.
• Use of the FORCE option can cause a server blade to lose data and possibly to become
unstable.
POWERON SERVER
Syntax
POWERON SERVER { ALL | <bay#>[{ , | - } <bay#>]} [{NORMAL | PXE | HDD
| RBSU }]
Description
Power on the specified server. Adding an optional boot argument forces the blade to ignore the
regular boot order and forces a boot using the specified method. If no blade is in the specified
bay, you are notified that the bay is empty.
Restrictions
This command functions only if the enclosure power is already on.
NOTE: Because the EMU hardware cannot determine if a blade is physically present unless
enclosure power is on, the EM reports the warning that the blade is not present if this command
is used when enclosure power is off.
REBOOT SERVER
Syntax
REBOOT SERVER { ALL | <bay#> [{ , | - } <bay#>]} [FORCE] [{NORMAL | PXE
| HDD | RBSU }]
Description
Sends an asynchronous request to the server to do a graceful shutdown of the OS. After the OS
has had sufficient time to perform a graceful shutdown, the server blade is power cycled. If the
FORCE option is specified, the server blade OS is not given the opportunity to perform a graceful
shutdown before power is removed but is cleanly powered off and then immediately powered
back on. The FORCE option can cause a server blade to lose data and possibly to become unstable.
Restrictions
This command functions only if the enclosure power is already on. Because the EMU hardware
cannot determine if a blade is physically present unless enclosure power is on, the EM reports the
warning that the blade is not present if this command is used when enclosure power is off.
SET SERVER UID
Syntax
SET SERVER UID { ALL | <bay#> [{ , | - } <bay#>]} { ON | OFF }
Description
Turns on or off the UID LED on the specified servers.
Restrictions
This command functions only if the enclosure power is already on.
