Power Strip Control; Powerman - Tripp Lite B092-016 Owner's Manual

Chapter 15: Advanced Configuration

15.9 Power Strip Control

The Console Server supports a growing list of remote power-control devices (RPCs) which can be configured using the
Management Console as described in Chapter 8. These RPCs are controlled using the open source NUT and PowerMan tools
and the pmpower utility.

15.9.1 PowerMan

PowerMan provides power management in a data center or compute cluster environment. It performs operations such as
power on, power off, and power cycle via remote power controller (RPC) devices. Target hostnames are mapped to plugs on
RPC devices in powerman.conf

Target Specification
powerman target hostnames may be specified as comma-separated or space-separated hostnames or host ranges. Host
ranges are of the general form: prefix[n-m,l-k,...], where n < m and l < k, etc., This form should not be confused with
regular expression character classes (also denoted by ''[]''). For example, foo[19] does not represent foo1 or foo9, but rather
represents a degenerate range: foo19.
This range syntax is meant only as a convenience on clusters with a prefix NN naming convention and specification of ranges
should not be considered necessary -- the list foo1,foo9 could be specified as such, or by the range foo[1,9].
Power ON targets.
Power OFF targets.
Power cycle targets.
Assert hardware reset for targets (if implemented by RPC).
Turn beacon ON for targets (if implemented by RPC).
Turn beacon OFF for targets (if implemented by RPC).
List available targets. If possible, output will be compressed into a host range (see TARGET
SPECIFICATION below).
Query plug status of targets. If none specified, query all targets. Status is not cached; each
time this option is used, powermand queries the appropriate RPC's. Targets connected to RPC's
that could not be contacted (e.g. due to network failure) are reported as status "unknown". If
possible, output will be compressed into host ranges.
Query node power status of targets (if implemented by RPC). If no targets are specified, query all
targets. In this context, a node in the OFF state could be ON at the plug but operating in standby
power mode.
Query beacon status (if implemented by RPC). If no targets are specified, query all targets.
Query node temperature (if implemented by RPC). If no targets are specified, query all targets.
Temperature information is not interpreted by powerman and is reported as received from the
RPC on one line per target, prefixed by target name.
Display option summary.
Show powerman license information.
Display the powerman version number and exit.
Displays RPC status information. If targets are specified, only RPC's matching the target list are
displayed.
Causes RPC telemetry information to be displayed as commands are processed. Useful for
debugging device scripts.
Expand host ranges in query responses.
