NAME

       ipmiutil_wdt- display and set WatchDog Timer parameters

SYNOPSIS

       ipmiutil wdt [-acdelrtx -N node -P/-R pswd -U user -EFJTVY]

DESCRIPTION

       ipmiutil  wdt  is  a  program  that  uses  IPMI commands to display and set WatchDog Timer
       parameters.

       This utility can use either any available IPMI driver, or direct user-space  IOs,  or  the
       IPMI LAN interface if -N.

       This  utility  is an example of how to access the IPMI watchdog parameters directly, which
       allows changing the timer configuration.

       There is an init script provided with ipmiutil  to  automate  the  task  of  managing  the
       watchdog timer in user-space.
       # chkconfig --add ipmiutil_wdt      (skip this if no chkconfig)
       # /etc/init.d/ipmiutil_wdt start
       This  sets  the  watchdog  timer to reset the system if the wdt is not restarted within 90
       seconds.  It creates an /etc/cron.d/wdt file to restart wdt every 60  seconds.   See  also
       ipmiutil UserGuide section 4.4 for more information.

OPTIONS

       Command line options are described below.

       -a N   Set watchdog event Action to N. Values: 0 = No action, 1 = Hard Reset(default), 2 =
              Power down, 3 = Power cycle.

       -c     Show watchdog output in a canonical format, with a default delimiter of '|'.

       -d     Disables the watchdog timer.

       -e     Enables the watchdog timer.  The timer is not actually started, however, until  the
              timer is reset.  The pre-timeout action is not enabled.

       -l     Set the watchdog dontLog bit to not log watchdog events in the SEL.

       -p N   Set watchdog Pretimeout event action to N. Values: 0 = No action(default), 1 = SMI,
              2 = NMI, 3 = Messaging Interrupt.  If this is set to an action other  than  0,  the
              pretimeout will also be set to 90% of the timeout.  However, if the timeout is less
              than 20 seconds, the pretimeout will not be enabled.

       -q S   Set watchdog pretimeout value to S seconds, rather than 90% of the  timeout  as  in
              -p.  The pretimeout value must be >= 5 and at least 5 seconds less than the timeout
              value.

       -r     Resets the watchdog timer.  This should be done every N seconds  if  the  timer  is
              running to prevent the watchdog action (usually a system reset) from occurring.

       -tN    Set the watchdog Timeout to N seconds.  The default is 120 seconds (2 minutes).

       -x     Causes extra debug messages to be displayed.

       -N nodename
              Nodename  or  IP  address of the remote target system.  If a nodename is specified,
              IPMI LAN interface is used.  Otherwise the local  system  management  interface  is
              used.

       -P/-R rmt_pswd
              Remote password for the nodename given.  The default is a null password.

       -U rmt_user
              Remote username for the nodename given.  The default is a null username.

       -E     Use the remote password from Environment variable IPMI_PASSWORD.

       -F drv_t
              Force  the  driver  type  to one of the followng: imb, va, open, gnu, landesk, lan,
              lan2, lan2i, kcs, smb.  Note that lan2i means lan2 with intelplus.  The default  is
              to detect any available driver type and use it.

       -J     Use   the   specified   LanPlus   cipher   suite  (0  thru  17):  0=none/none/none,
              1=sha1/none/none,   2=sha1/sha1/none,   3=sha1/sha1/cbc128,   4=sha1/sha1/xrc4_128,
              5=sha1/sha1/xrc4_40, 6=md5/none/none, ... 14=md5/md5/xrc4_40.  Default is 3.

       -T     Use  a  specified  IPMI  LAN  Authentication Type: 0=None, 1=MD2, 2=MD5, 4=Straight
              Password, 5=OEM.

       -V     Use  a  specified  IPMI  LAN  privilege  level.  1=Callback  level,  2=User  level,
              3=Operator level, 4=Administrator level (default), 5=OEM level.

       -Y     Yes,  do  prompt  the  user for the IPMI LAN remote password.  Alternatives for the
              password are -E or -P.
