I encountered on a CX4-120 storage array the situation whereby some “stale” hosts were unable to be deleted. I tried using the console, but it’s in my opinion unstructured and difficult to use.
During troubleshooting I found out the “Engineering mode” password is “messner” (without the quotes). This mode can be accessed by opening the Navi GUI (Enterprise Storage) and pressing ctrl+shift+F12. This mode allows some additional functionalities.
The purposes of my my actions was to re-initialize the array (clear the configuration and startover). I used the navisecCLI to assist me in this matter.
