NAME

powerman.conf - configuration file for PowerMan

CONTENTS

Description
Example

DESCRIPTION

The powerman.conf file typically includes one or more of the remote power controller (RPC) device files provided in the /usr/local/etc/powerman directory; sets a few global options; instantiates RPC devices with unique names, hostnames, and ports; and maps node names to RPC’s and plug numbers.

Network-attached RPC’s are instantiated with device lines of the form:
device "name" "type" "host:port"
Serial-attached RPC’s are instantiated with device lines of the form:
device "name" "type" "special file" "flags"
where special file is the full path to a tty device, and flags is a serial parameter specification in a form similar to that used by lilo, e.g. "9600,8n1". RPC’s that are accessed via coprocesses are instantiated as follows:
device "name" "type" "process |&"
where process is the full path to a process whose standard output and input will be controlled by powerman, e.g. "/usr/bin/conman -Q -j rpc0 |&".

EXAMPLE

The following example is a 16-node cluster that uses two 8-plug Baytech RPC-3 remote power controllers.

include "/usr/local/etc/powerman/baytech.dev"  # include def for "baytech" RPC

tcpwrappers yes # enable TCP wrappers

# listen "0.0.0.0:10101" # uncomment to listen on all interfaces

# Alias example - alias can be used in target specifications alias "pengra_service" "pengra[0-1]" alias "pengra_compute" "pengra[2-15]"

# Power controller: device <name> <type> <hostname:port> [<flags>] device "pow0" "baytech" "pow0:23" # instantiate pow0 device "pow1" "baytech" "pow1:23" # instantiate pow1

# Plugs: node <name> <device> [<plug>] node "pengra[0-7]" "pow0" "[1-8]" # map pengra0...pengra7 to pow0 plug 1-8 node "pengra[8-15]" "pow1" "[1-8]" # map pengra8...pengra15 to pow1 plug 1-8
