15.9 Power Strip Control
The console server supports a growing list of remote power-control devices (RPCs) that you can
configure using the Management Console as described in Chapter 8. These RPCs are controlled using the
open source PowerMan and Network UPS Tools and with Black Box’s pmpower utility.
15.9.1 The PowerMan tool
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.
Synopsis
powerman [-option] [targets]
pm [-option] [targets]
Options
-1, --on Power ON targets.
-0, --off Power OFF targets.
-c, --cycle Power cycle targets.
-r, --reset Assert hardware reset for targets (if implemented by RPC).
-f, --flash Turn beacon ON for targets (if implemented by RPC).
-u, --unflash Turn beacon OFF for targets (if implemented by RPC).
-l, --list List available targets. If possible, output will be compressed into a host range (see TARGET
SPECIFICATION below).
-q, --query 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.
-n, --node Query node power status of targets (if implemented by RPC). If no targets 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.
-b, --beacon Query beacon status (if implemented by RPC). If no targets are specified, query all
targets.
-t, --temp 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.
-h, --help Display option summary.
-L, --license Show powerman license information.
-d, --destination host[:port] Connect to a powerman daemon on non-default host and optionally port.
-V, --version Display the powerman version number and exit.
-D, --device Displays RPC status information. If targets are specified, only RPC's matching the target
list are displayed.
-T, --telemetry Causes RPC telemetry information to be displayed as commands are processed. Useful
for debugging device scripts.
-x, --exprange Expand host ranges in query responses.
