nut-ipmipsu - Driver for IPMI Power Supply Units (PSU)
This driver is experimental, and still a work-in-progress. Feedback is
This man page only documents the hardware-specific features of the nut-ipmipsu
driver. For information about the core driver, see nutupsdrv
This driver should support a wide range of PSUs through local IPMI interface.
nut-ipmipsu currently use the GNU FreeIPMI project, for IPMI implementation.
This driver doesn’t support any optional settings.
This driver is not built by default. You can build it by using "configure
You also need to give proper permissions on the local IPMI device file
(/dev/ipmi0 for example) to allow the NUT user to access it.
An udev rules file (nut-ipmipsu.rules) is provided and automatically installed
on udev enabled system. This file is generally installed in /etc/udev/rules.d/
or /lib/udev/rules.d/ on newer systems, to address the permission settings
problem. For more information, refer to nut/scripts/udev/README.
This driver doesn’t support any instant commands.
The "port" value is used to identify the PSU. For instance, to target
FRU 0x2, use the following in ups.conf
driver = nut-ipmipsu
port = id2
This driver will report various information related to a PSU, including:
•manufacturer, model, serial and part
•nominal voltage and frequency,
•actual current and voltage,
•status of the PSU:
•OL means that the PSU is
present and providing power,
•OFF means that the PSU is
present but not providing power (power cable removed),
•stale (no data) means that the
PSU is not present (ie physically removed).
Here is an example output for a Dell r610 server:
device.mfr.date: 01/05/11 - 08:51:00
device.model: PWR SPLY,717W,RDNT
driver.version.data: IPMI PSU driver
