If configured and the switch detects a hardware fault and enters the shutdown state, this command clears the shutdown state and renders the switch, I/O, or MSM/MM module(s) operational.
This command has no arguments or variables.
N/A.
If you configure the switch or one or more modules to shutdown upon detecting a hardware fault, and the switch or module enters the shutdown state, you must explicitly clear the shutdown state and reset the switch or the affected modules for the switch to become operational.
To clear the shutdown state, use the following command: clear sys-recovery-level
The switch prompts you to confirm this action. The following is a sample confirmation message:
Are you sure you want to clear sys-recovery-level? (y/n)
Enter y to confirm this action and clear the shutdown state. Enter n or press [Enter] to cancel this action.
On a modular switch, after using the clear sys-recovery-level command, you must reset each affected module.
If you configured only a few I/O modules to shutdown, reset each affected I/O module as follows:
Disable the slot using the disable slot slot command.
Re-enable the slot using the enable slot slot command.
Note
You must complete this procedure for each module that enters the shutdown state.If you configured all I/O modules or one or more MSMs/MMs to shut down, use the reboot command to reboot the switch and reset all affected modules.
After you clear the shutdown state and reset the affected module, each port is brought offline and then back online before the module and the entire system is operational.
On a Summit family switch, after you clear the shutdown state, use the reboot command to bring the switch and ports back online. After you use the reboot command, the switch is operational.
When an exclamation point (!) appears in front of the command line prompt , it indicates that one or more slots of a modular switch or the entire stand-alone switch is shut down as a result of your hardware recovery configuration and a switch error.
The following is truncated sample output of the command line prompt for a modular switch:
The I/O modules in the following slots are shut down: 1,3 Use the "clear sys-recovery-level" command to restore I/O modules ! BD-8810.1 #
The following is sample output for a Summit switch:
All switch ports have been shut down. Use the "clear sys-recovery-level" command to restore all ports. ! SummitX #
The following example clears the shutdown state:
clear sys-recovery-level
This command was first available in ExtremeXOS 11.5.
This command is available on all platforms.
