       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 powerman.conf(5).


       -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

       -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

       -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

       -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.


       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
