SOL7550: Resetting the BIG-IP system configuration to the factory default settings using the sys-reset command
Updated: 7/22/09 2:52 PM
Beginning with BIG-IP LTM version 9.4, you can restore all system configurations to factory default values using the sys-reset command.
Note: The sys-reset command was removed in BIG-IP version 10.0.1.
Note: For information about resetting the BIG-IP system for versions 9.0 through 9.3, refer to SOL6887: Resetting the BIG-IP system configuration to the default settings.
Restoring the BIG-IP LTM to factory default values using the sys-reset command removes all system configuration settings, including the licensing information. All files that are not recorded in the RPM database will also be removed.
The sys-reset command runs the sys-icheck utility, which identifies any unintended modifications to BIG-IP system files. If the sys-icheck utility does not find any system integrity issues, it returns the system to the factory default state.
Note: For more information, refer to SOL9118: Overview of the sys-icheck utility.
Description of the sys-reset command
When you reset the BIG-IP LTM to factory defaults, the sys-reset command performs the following tasks:
- Removes all BIG-IP system configuration and restores the factory default values
- Removes system licensing information
- Resets system passwords and the hostname to default settings
- Removes all files in the /shared partition
- Preserves management interface settings

Running sys-reset
To run the sys-reset command, perform one of the following procedures based on the configuration of your BIG-IP system:
- A system with multiple partitions
- A system with single partitions
- A system with hotfix packages installed
Running sys-reset on BIG-IP systems with multiple partitions
You can run the sys-reset command on systems with single or multiple partitions. When you run the sys-reset utility on systems with multiple partitions, all BIG-IP system configuration information is removed from the partition on which sys-reset was run. Configuration information on other partitions is not altered.
The following BIG-IP systems contain multiple partitions:
- BIG-IP 520 and 540 (D35)
- BIG-IP 1500 (C36)
- BIG-IP 1600 (C102)
- BIG-IP 3400 (C62)
- BIG-IP 3410 (C100)
- BIG-IP 3600 (C103)
- BIG-IP 6400 (D63)
- BIG-IP 6800 (D68)
- BIG-IP 8400 (D84)
- BIG-IP 8800 (D88)
Note: You must be local to the BIG-IP system with a console connection to perform this procedure.
To run the sys-reset utility on systems with multiple partitions, perform the following procedure:
- Log in to the command line from the system console.
- Boot the BIG-IP system to the partition from which you want to run the sys-reset command.
Note: For more information, refer to SOL5658: Overview of the switchboot utility. - Back up the system license file to a remote location.
- Set the system run level to single user mode by typing the following command:
init 1
Important: The procedure outlined in SOL4178: Booting BIG-IP in single-user mode should not be used to set the machine to single-user mode when running the sys-reset utility. - From the prompt, type the following command:
sys-reset
A message will display indicating that the system reset is complete. - Reboot the device by typing the following command:
reboot
The BIG-IP system configuration has been restored to the factory default values.
Running sys-reset on BIG-IP systems with single partitions
You can run the sys-reset command on systems with single or multiple partitions. When you run the sys-reset utility on systems with a single partition, all BIG-IP system configuration information is removed from the partition.
The following BIG-IP systems contain a single partition:
- BIG-IP 1000 D39
- BIG-IP 2400 D44
- BIG-IP 5100 D51
- BIG-IP 5110 D51
Note: You must be local to the BIG-IP system with a console connection to perform this procedure.
To run the sys-reset utility on systems with a single partition, perform the following procedure:
- Log in to the command line from the system console.
- Back up the system license file to a remote location.
- Set the system run level to single user mode by typing the following command:
Note: This step is not required in BIG-IP version 10.0.0 and later. Proceed to step 4.
init 1
Important: The procedure outlined in SOL4178: Booting BIG-IP in single-user mode should not be used to set the machine to single-user mode when running the sys-reset utility. - From the prompt, type the following command:
sys-reset
A message will display indicating that the system reset is complete. - Reboot the device by typing the following command:
reboot
The BIG-IP system configuration has been restored to the factory default values.
Running sys-reset with the -p option
The sys-reset -p option runs sys-reset ignoring any hotfixes that have been applied to the system.
Note: F5 Networks does not recommended running sys-reset on a system in which a hotfix is installed. If you plan to run the sys-reset utility to restore a system to factory default values, you should first uninstall the hotfix. For more information about managing hotfixes, refer to SOL6845: Managing F5 Networks product hotfixes.
Preserving the /shared partition
By default, the sys-reset utility removes all files in the /shared partition. You can run the sys-reset command and have the system preserve all files in the /shared partition by typing the following sys-reset command:
sys-reset -s
