It creates an /etc/cron.d/wdt file to +restart wdt every 60 seconds. +See also ipmiutil UserGuide section 4.4 for more information. + +.SH OPTIONS +Command line options are described below. +.IP "-a N" +Set watchdog event Action to N. Values: +0 = No action, 1 = Hard Reset(default), 2 = Power down, 3 = Power cycle. +.IP "-c" +Show watchdog output in a canonical format, with a default delimiter of '|'. +.IP "-d" +Disables the watchdog timer. +.IP "-e" +Enables the watchdog timer. The timer is not actually started, however, +until the timer is reset. The pre-timeout action is not enabled. +.IP "-l" +Set the watchdog dontLog bit to not log watchdog events in the SEL. +.IP "-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. +.IP "-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. +.IP "-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. +.IP "-tN" +Set the watchdog Timeout to N seconds. The default is 120 seconds (2 minutes). +.IP "-x" +Causes extra debug messages to be displayed. +.IP "-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. +.IP "-P/-R rmt_pswd" +Remote password for the nodename given. The default is a null password. +.IP "-U rmt_user" +Remote username for the nodename given. The default is a null username. +.IP "-E" +Use the remote password from Environment variable IPMI_PASSWORD. +.IP "-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. +.IP "-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. +.IP "-T" +Use a specified IPMI LAN Authentication Type: 0=None, 1=MD2, 2=MD5, 4=Straight Password, 5=OEM. +.IP "-V" +Use a specified IPMI LAN privilege level. 1=Callback level, 2=User level, 3=Operator level, 4=Administrator level (default), 5=OEM level. +.IP "-Y" +Yes, do prompt the user for the IPMI LAN remote password. +Alternatives for the password are \-E or \-P. + + +.SH "SEE ALSO" +ialarms(8) iconfig(8) icmd(8) idiscover(8) ievents(8) ifirewall(8) +ifru(8) ifruset(8) ifwum(8) igetevent(8) ihealth(8) ihpm(8) +ilan(8) ipicmg(8) ireset(8) isel(8) isensor(8) iserial(8) isol(8) isunoem(8) +iwdt(8) ipmiutil(8) ipmi_port(8) + +.SH WARNINGS +See http://ipmiutil.sourceforge.net/ for the latest version of ipmiutil and any bug fix list. + +.SH COPYRIGHT +Copyright (C) 2009 Kontron America, Inc. +.PP +See the file COPYING in the distribution for more details +regarding redistribution. +.PP +This utility is distributed in the hope that it will be useful, but +WITHOUT ANY WARRANTY. + +.SH AUTHOR +.PP +Andy Cress <arcress at users.sourceforge.net> +.br + |
