Disconnected UPS and controller cannot boot

[Joshua Goi]

Hi all,

I have just disconnected my UPS from B180L and now it doesn't boot. I see the error message,
Start CheckUPS Data Server Daemon.............................................OK
CheckUPS reports: Unable to find UPS on [IP address]

It looks like the system is looking for the UPS that is no longer there. Is there anyway I can disable the daemon or tell the system not to look for the UPS?

Thanks!

Yes, bring the system up in single-user mode and then edit the corresponding file in /etc/rc.config.d OR remove the symbolic links in the /sbin/rc.N/directory that links the 'S' startup scripts to the actual file in /sbin/init.d. Editing the configuration file in /etc/rc.config.d is considered the better approach. Note: You will need to manually mount /var and /usr in single-user mode in order to use vi.

PS: It is considered good practice to disable daemons BEFORE removing related hardware.
