PowerVault MD3820f - Controller Locked (SOD Lockdown)

Hi,

here are a few things you can try to get access to the console or clear the SOD Lockdown:

1. Change the baud rate on your serial connection from 115200 to 9600. That’s the correct setting for these controllers.
2. Try swapping the controller slots or booting with just the affected controller installed.
3. If you can access the working controller via serial, try running these commands:

   cmgrSetAltToOptimal
   altCtlReset 2
   resetController_MT 1
   

What I’d personally try next is connecting the serial cable directly to the affected controller and running lemClearLockdown. That command can sometimes clear the lockdown state.

However, if the controller reboots and still comes back in lockdown, then you’ll need to contact Dell Support. They can clear the error using internal tools and make sure it doesn’t get stuck again after reboot.

Just a heads up: the only way to fully clear a lockdown caused by database corruption is through VXshell, which requires Dell’s internal credentials. We can’t share the username/password, so a support call is usually necessary.

Hope that helps!

Sorry, unfortunately I’m not aware of any other method that would work in this situation. You may want to contact phone support for further investigation.
