NAME

7       fence_netio - I/O Fencing agent for Koukaam NETIO-230B
8

DESCRIPTION

10       fence_netio  is an I/O Fencing agent which can be used with the Koukaam
11       NETIO-230B Power Distribution Unit. It logs into device via telnet  and
12       reboots  a  specified  outlet.  Lengthy  telnet  connections  should be
13       avoided while a GFS cluster is  running  because  the  connection  will
14       block any necessary fencing actions.
15
16       fence_netio  accepts options on the command line as well as from stdin.
17       Fenced  sends  parameters  through  stdin  when  it  execs  the  agent.
18       fence_netio  can  be  run by itself with command line options.  This is
19       useful for testing and for turning outlets on or off from scripts.
