       powerman - power on/off nodes


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


       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


       -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


       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 necessary to  enclose  ranged  lists  within
       quotes.  For example, in tcsh, the last example above should be executed as:
           powerman --on "foo[0,4-5]"




       PowerMan  was  originally  developed  by  Andrew  Uselton  on LLNL's Linux clusters.  This
       software is open source and distributed under the terms of the GNU GPL.
