nut-ipmipsu - Driver for IPMI Power Supply Units (PSU)


nut-ipmipsu -h nut-ipmipsu -a PSU_NAME [OPTIONS] Note This driver is experimental, and still a work-in-progress. Feedback is encouraged. Note This man page only documents the hardware-specific features of the nut-ipmipsu driver. For information about the core driver, see nutupsdrv(8).


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 --with-ipmi=yes". 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: [pdu] driver = nut-ipmipsu port = id2 This driver will report various information related to a PSU, including: · manufacturer, model, serial and part numbers, · 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: DELL 01/05/11 - 08:51:00 device.model: PWR SPLY,717W,RDNT device.part: 0RN442A01 device.serial: CN179721130031 device.type: psu nut-ipmipsu driver.parameter.pollinterval: 2 driver.parameter.port: id2 driver.version: 2.6.1-3139M IPMI PSU driver driver.version.internal: 0.01 input.current: 0.20 input.frequency.high: 63 input.frequency.low: 47 input.voltage: 232.00 input.voltage.maximum: 264 input.voltage.minimum: 90 2 ups.realpower.nominal: 717 ups.status: OL ups.voltage: 12
