SYNOPSIS

DESCRIPTION

14       fence_mcdata  is  an I/O Fencing agent which can be used with McData FC
15       switches.  It logs into a McData switch via telnet and disables a spec‐
16       ified  port.  Disabling the port which a machine is connected to effec‐
17       tively fences that machine.  Lengthy telnet connections to  the  switch
18       should be avoided while a GFS cluster is running because the connection
19       will block any necessary fencing actions.
20
21       fence_mcdata accepts options on the command line as well as from stdin.
22       fenced  sends  parameters  through  stdin  when  it  execs  the  agent.
23       fence_mcdata can be run by itself with command line  options  which  is
24       useful for testing.
25
26       After  a  fence  operation  has  taken  place the fenced machine can no
27       longer connect to the McData FC switch.  When  the  fenced  machine  is
28       ready  to  be brought back into the GFS cluster (after reboot) the port
29       on the McData FC switch needs to be enabled. This can be done  by  run‐
30       ning fence_mcdata and specifying the enable action.
