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.
