Software for Linux Owner's manual

15 Remote server controls
The menu items on the Tools→Server Controls menu enable you to remotely manage power control
on a physical managed system.
IMPORTANT: Be aware that the Insight Control for Linux server controls operate by contacting
the management processor of the server directly and executing the requested power function. That
means that servers are powered off or cycled abruptly without a graceful shutdown.
If you use these tools on a server with a running operating system, that operating system is powered
down without running the normal shutdown commands.
This chapter addresses the following topics:
• “Powering off a managed system” (page 141)
• “Powering on a managed system” (page 141)
• “Rebooting a managed system” (page 141)
• “HP Insight Control power management” (page 141)
15.1 Powering off a managed system
NOTE: Before powering off a virtual host, perform a graceful shutdown on all its virtual guests.
Use the Tools→Server Controls→Power Off Server... option to power off one or more target
managed systems.
This task makes a remote call to the management processor to set power status to off.
15.2 Powering on a managed system
Use the Tools→Server Controls→Power On Server... option to power off one or more target managed
systems.
This task makes a remote call to the management processor to set power status to on.
15.3 Rebooting a managed system
Use the Tools→Server Controls→Reboot Server... option to reboot one or more target managed
systems.
The reboot operation reboots the server by using the power off functionality of the management
processor, waiting a predetermined amount of time, and using the power on functionality of the
management processor. These operations require the management processor credentials to be set
in order to perform power control. For more information on management processor credentials,
see “Management Processor Credentials” (page 198).
15.4 HP Insight Control power management
Insight Control for Linux incorporates the Insight Control power management plug-in to HP SIM.
Insight Control power management is an integrated power monitoring and management application
that provides centralized control of server power consumption and thermal output. It enables you
to reduce the amount of power and cooling required for ProLiant servers.
