[Linux-HA] STONITH smart-ups 1500I

[Etienne van Tonder]

Hi Alan,

Thank you for all your help it's much appreciated.

I have one more problem, I'm running apcupsd to monitor for power failures
so that the system can shutdown cleanly. When I start the apcupsd daemon and
execute:

stonith -t apcsmart -p "/dev/ttyS0 beta" -S

it returns with the following error:

CRITICAL **: APC_open_serialport: Could not lock tty /dev/ttyS0 (rc: -1)

If I stop apcupsd then it all works ok.

Regards,

Etienne.
