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.
