We are working on a project to safely shutdown a cluster. We are using
an APC Back-up UPS ES 500. We have found a driver called apcupsd, which
is documented to work only with a usb interface for Linux.
We are wondering if anyone is working on porting apcupsd with the usb
interface to Mac OS X?
You shouldn't need to port anything.
Mac OS X 10.3.x supports most UPS devices with USB ports without any
additional drivers. New information appears in the Energy Saver prefs
panel when a UPS is connected.
You'll probably need to write a script on the machine connected to
the UPS to shut down the other machines in the cluster.
See the first section in
http://developer.apple.com/documentation/Hardware/Developer_Notes/Servers/XserveG5/1Introduction/chapter_2_section_4.html
*UPS support: Mac OS X Server contains an enhanced version of UPS
support that supports serial and USB UPS devices. The Power Manager
has been enhanced to allow UPS vendors to communicate directly with
the Power Manager to control their UPS hardware. UPS settings can be
made in the Energy Saver preference pane and with the pmset command.
See man pmset for more infomation.
The Server Monitor application shows status of the UPS.
An editable UPS shutdown script that will run when the machine
powers down because of UPS is available in the
/user/libexec/upsshutdown directory.
