rp7410 running 11.11 - UPS issue

Hi All,

We recenlty replaced the battery of a power trust II ups connected to a rp7410 running 11.11.

we had a power glitch for couple seconds and the system rebooted right away it did not use the 5 minutes setting in /etc/ups_conf:


we tested again by unplugging replugging within 1 minute and the same issue happened again. the system rebooted.

ps -ef: shows that ups_mond is running.

#ioscan -funC tty:

Class I H/W Path Driver S/W State H/W Type Description


tty 1 1/0/0/0/0 func0 CLAIMED INTERFACE PCI BaseSystem (103c128d)

tty 0 1/0/0/0/1 asio0 CLAIMED INTERFACE PCI Serial (103c1048)

/dev/GSPdiag1 /dev/diag/mux0 /dev/mux0 /dev/tty0p0 /dev/tty0p1 /dev/tty0p2

ups_mond patch for 11.11 is installed.

Your help is much appreciated.
Thank you in advance.

The problem might not be with your HP-UX system or the ups_mond configuration.

The problem may be that you got a bad battery. The symptoms you are describing sound like the UPS is not providing sufficient power to keep your system up and running when you pull the plug on the UPS.

Double check the UPS and try to verify that the battery is good.
