pbsnodes(8B)                          PBS                         pbsnodes(8B)

NAME
       pbsnodes - pbs node manipulation

SYNOPSIS
       pbsnodes [-{a|x}] [-q] [-s server] [node|:property]
       pbsnodes -l [-q] [-s server] [state] [nodename|:property ...]
       pbsnodes [-{c|d|o|r}] [-q] [-s server] [-n] [-N "note"] [node|:property]

DESCRIPTION
       The  pbsnodes command is used to mark nodes down, free or offline.  It can
       also be used to list nodes and their state.  Node information is  obtained
       by sending a request to the PBS job server.  Sets of nodes can be operated
       on at once by specifying a node property prefixed by a colon.
       Nodes do not exist in a single state, but actually have a set  of  states.
       For  example,  a  node  can  be  simultaneously "busy" and "offline".  The
       "free" state is the absence of all other states and so is  never  combined
       with other states.

       In  order  to  execute  pbsnodes with other than the -a or -l options, the
       user must have PBS Manager or Operator privilege.

OPTIONS
       -a             All attributes of a node or all nodes are listed.  This  is
                      the default if no flag is given.

       -x             Same as -a, but the output has an XML-like format.

       -c             Clear OFFLINE from listed nodes.

       -d             Print  MOM  diagnosis  on the listed nodes.  Not yet imple-
                      mented.  Use momctl instead.

       -o             Add the OFFLINE state.  This is different from being marked
                      DOWN.  OFFLINE prevents new jobs from running on the speci-
                      fied nodes.  This gives the administrator a tool to hold  a
                      node  out  of  service without changing anything else.  The
                      OFFLINE state will never be set or cleared automatically by
                      pbs_server; it is purely for the manager or operator.

       -p             Purge  the  node  record  from  pbs_server.  Not yet imple-
                      mented.

       -r             Reset the listed nodes by clearing OFFLINE and adding  DOWN
                      state.  pbs_server will ping the node and, if they communi-
                      cate correctly, free the node.

       -l             List node names and their state.  If no state is specified,
                      only  nodes  in  the  DOWN,  OFFLINE, or UNKNOWN states are
                      listed.  Specifying a state string acts as an  output  fil-
                      ter.   Valid  state  strings are "free", "offline", "down",
                      "reserve", "job-exclusive", "job-sharing",  "busy",  "time-
                      shared", or "state-unknown".

       -N             Specify  a  "note" attribute.  This allows an administrator
                      to add an arbitrary annotation to  the  listed  nodes.   To
                      clear a note, use -N "" or -N n.

       -n             Show the "note" attribute for nodes that are DOWN, OFFLINE,
                      or UNKNOWN.  This option requires -l.

       -q             Supress all error messages.

       -s             Specify the PBS server’s hostname or IP address.
