NAME

       powerman - power on/off nodes

SYNOPSIS

       pm [-options] -action [targets] [-action [targets] ...]

DESCRIPTION

       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(5).

OPTIONS

       -1, --on targets
              Power ON targets.

       -0, --off targets
              Power OFF targets.

       -c, --cycle targets
              Power cycle targets.

       -r, --reset targets
              Assert hardware reset for targets (if implemented by RPC).

       -f, --flash targets
              Turn beacon ON for targets (if implemented by RPC).

       -u, --unflash targets
              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-all
              Query plug status of 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.

       -Q, --query targets
              Query plug status of specific targets.

       -n, --soft-all
              Query soft power status of all targets (if implemented by RPC).  In this context, a node in the OFF state could be ON  at  the  plug
              but operating in standby power mode.

       -N, --soft targets
              Query soft power status of specific targets (if implemented by RPC).

       -b, --beacon-all
              Query beacon status of all targets (if implemented by RPC).

       -B, --beacon targets
              Query beacon status of specific targets (if implemented by RPC).

       -t, --temp-all
              Query  node  temperature  of  all  targets  (if  implemented by RPC).  Temperature information is not interpreted by powerman and is
              reported as received from the RPC on one line per target, prefixed by target name.

       -P, --temp targets
              Query node temperature of specific targets (if implemented by RPC).

       -h, --help
              Display option summary.

       -L, --license
              Show powerman license information.

       -h, --server-host 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.

       -g, --genders
              If configured with the genders(3) package, this option tells powerman that targets are genders attributes that  map  to  node  names
              rather than the node names themselves.

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 prefixNN 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].

       Some examples of powerman targets follows:

       Power on hosts bar,baz,foo01,foo02,...,foo05
           powerman --on bar baz foo[01-05]

       Power on hosts bar,foo7,foo9,foo10
           powerman --on bar,foo[7,9-10]

       Power on foo0,foo4,foo5
           powerman --on foo[0,4-5]

       As a reminder to the reader, some shells will interpret brackets ([ and ]) for pattern matching.  Depending on your shell, it may be neces-
       sary to enclose ranged lists within quotes.  For example, in tcsh, the last example above should be executed as:
           powerman --on "foo[0,4-5]"
