NAME

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

SYNOPSIS

Note
Two NUT websites

This version of the page reflects NUT release v2.8.1 with codebase commited 4ba352d8f at 2023-10-31T21:46:20+01:00

Options, features and capabilities in current development (and future releases) are detailed on the main site and may differ from ones described here.

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).

SUPPORTED HARDWARE

This driver should support a wide range of PSUs through local IPMI interface.

nut-ipmipsu currently use the GNU FreeIPMI project, for IPMI implementation.

EXTRA ARGUMENTS

This driver doesn’t support any optional settings.

INSTALLATION

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.

INSTANT COMMANDS

This driver doesn’t support any instant commands.

IMPLEMENTATION

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 (i.e. physically removed).
