Module Recovery Actions--BlackDiamond 8800 Series Switches and BlackDiamond X8 Series Switches Only

The following table describes the actions module recovery takes based on your module recovery setting.

For example, if you configure a module recovery setting of reset for an I/O module, the module is reset a maximum of five times before it is taken permanently offline.

From left to right, the columns display the following information:

Module Recovery Setting—This is the parameter used by the configure sys-recovery-level slot command to distinguish the module recovery behavior.
Hardware—This indicates the hardware that you may have installed in your switch.
Action Taken—This describes the action the hardware takes based on the module recovery setting.

Module Recovery Actions for the BlackDiamond X8 and 8800 Series Switches

Module Recovery Setting	Hardware	Action Taken
none
	Single MSM	The MSM remains powered on in its current state. This does not guarantee that the module remains operational; however, the switch does not reboot the module.
	Dual MSM	The MSM remains powered on in its current state. This does not guarantee that the module remains operational; however, the switch does not reboot the module.
	I/O Module	The I/O module remains powered on in its current state. The switch sends error messages to the log and notifies you that the errors are ignored. This does not guarantee that the module remains operational; however, the switch does not reboot the module.
reset
	Single MSM	Resets the MSM.
	Dual MSM	Resets the primary MSM and fails over to the backup MSM.
	I/O Module	Resets the I/O module a maximum of five times. After the fifth time, the I/O module is permanently taken offline.
shutdown
	Single MSM	The MSM is available for debugging purposes only (the I/O ports also go down); however, you must clear the shutdown state using the clear sys-recovery-level command for the MSM to become operational. After you clear the shutdown state, you must reboot the switch. For more information see, Clearing the Shutdown State.
	Dual MSM	The MSMs are available for debugging purposes only (the I/O ports also go down); however, you must clear the shutdown state using the clear sys-recovery-level command for the MSM to become operational. After you clear the shutdown state, you must reboot the switch. For more information see, Clearing the Shutdown State.
	I/O Module	Reboots the I/O module. When the module comes up, the ports remain inactive because you must clear the shutdown state using the clear sys-recovery-level command for the I/O module to become operational. After you clear the shutdown state, you must reset each affected I/O module or reboot the switch. For more information see, Clearing the Shutdown State.
