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.
We had 3 hosts which were stuburn and we did not get removed from the console. In first case we executed the command:
naviseccli -h 10.32.76.44 port -removeHBA -all. Please note we do not pass any username and password in this command. This is because we opted to create a password file to ease the operations.
During the execution we were able to delete 2 of the 3 hosts in the console. The 3rd one gave us the error “only logged out but registered initiator records will be removed”. Eventually I noticed the ports were still logged in. The zoning configuration still exist and the particular server still had access to the storage box. After removing the configuration and executing the
naviseccli -h 10.32.76.44 port -removeHBA -all again, the server was successfully removed.
