Managing the Locator Indicator

Immediate Shutdown
An immediate shutdown of the server (also referred to as an emergency shutdown) should be
used only in situations when you know that the loss of data is nonexistent or acceptable. An
immediate shutdown does not warn users, does not properly close files, nor does it prepare the
file system for shut down to standby power mode.
Complete Power Removal
Shutting down the server from full power mode to standby power mode does not completely
remove power from the server. When it is in standby power mode, the server is in a low-power
state. This low-power state is enough to maintain the service processor (SP), which runs Oracle
ILOM. To completely remove power from the server, you need to remove the power cords.
Warm Reset or Reboot
A warm reset is a reboot or restart of the server. It involves cycling the server power from
full power mode to standby power mode and back to full power mode. For example, a warm
reset might be required after a software or firmware update or when you want to launch Oracle
System Assistant or the BIOS Setup Utility.
Cold Reset
A cold reset of the server is a restart of the server from a completely powered-off state. A cold
reset might be required to resolve a system issue. To perform a cold reset, place the server in
standby power mode, disconnect the server from its power source by performing a complete
power removal (see above), wait 30-60 seconds, and then connect the server to its power
source.
