Omcong System Recovery Or Omcong Servermodule
Recovery
Use the omcong system recovery or omcong servermodule recovery command to set the action when the operating system hangs or
crashes. You can also set the number of seconds that must pass before the system is considered to have a hung operating system. The
following table lists the valid parameters for the command
NOTE: The upper and lower limits for the timer depend on the system model and conguration.
Table 74. Valid Parameters Of Omcong System Recovery Or Omcong Servermodule Recovery
name=value pair Description
action=none Takes no action when the operating system is hung or has crashed.
action=reboot Shuts down the operating system and initiates system startup, performing BIOS checks, and reloading the
operating system.
action=powero Turns o electrical power to the system.
action=powercycle Turns o electrical power to the system, pauses, turns on the power, and reboots the system. Power cycling
is useful when you want to reinitialize system components such as hard drives.
timer=<n> Number of seconds that must pass before the system is considered to have a hung operating system (from
20 seconds to 480 seconds).
Example Recovery Commands
To set the action on hung operating system detection to powercycle, type:
omconfig system recovery action=powercycle
or
omconfig servermodule recovery action=powercycle
To set the system to hang for 120 seconds, before a recovery action is initiated, type:
omconfig system recovery timer=120
or
omconfig servermodule recovery timer=120
Omcong System Shutdown Or Omcong Servermodule
Shutdown
Use the omcong system shutdown or omcong servermodule shutdown command to determine how the system shuts down. During
system shutdown, the default is to shut down the operating system before powering o the system. Shutting down the operating system
rst closes down the le system before powering the system down. If you do not want to shut down the operating system rst, use the
osrst=false parameter.
NOTE
: The parameter osrst=false is not available on 13th generation and later systems. By default, on 13th generation and later
systems, the operating system shuts down before turning o the server during a remote shutdown.
