omconfig system recovery

Use the omconfig system recovery command to set the action that is to be taken when the operating system has hung or crashed. You can also set the number of seconds that must pass before the system is considered to have a hung operating system. Table 4-28 shows the valid parameters for the command.

NOTE: Upper and lower limits for the timer are dependent on your system model and configuration.

Table 4-28. Recovery Parameters

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=poweroff

Turns off electrical power to the system.

action=powercycle

Turns off electrical power to the system, pauses, turns the power on, 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 a 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

To set the amount of time that the system must be hung before a recovery action is initiated to 120 seconds, type:

omconfig system recovery timer=120

omconfig system shutdown

Use the omconfig system shutdown command to determine how the system shuts down. During system shutdown, the default is to shut down the operating system before powering off the system. Shutting down the operating system first closes down the file system before powering the system down. If you do not want to shut down the operating system first, you can use the parameter osfirst=false. Table 4-29 shows the valid parameters for the command.
