13 ipmiutil wdt is a program that uses IPMI commands to display and set
14 WatchDog Timer parameters.
15
16 This utility can use either any available IPMI driver, or direct user-
17 space IOs, or the IPMI LAN interface if -N.
18
19 This utility is an example of how to access the IPMI watchdog parame‐
20 ters directly, which allows changing the timer configuration.
21
22 There is an init script provided with ipmiutil to automate the task of
23 managing the watchdog timer in user-space.
24 # chkconfig --add ipmiutil_wdt (skip this if no chkconfig)
25 # /etc/init.d/ipmiutil_wdt start
26 This sets the watchdog timer to reset the system if the wdt is not
27 restarted within 90 seconds. It creates an /etc/cron.d/wdt file to
28 restart wdt every 60 seconds. See also ipmiutil UserGuide section 4.4
29 for more information.

31
33 Command line options are described below.
34
35 -a N Set watchdog event Action to N. Values: 0 = No action, 1 = Hard
36 Reset(default), 2 = Power down, 3 = Power cycle.
37
38 -c Show watchdog output in a canonical format, with a default
39 delimiter of '|'.
40
41 -d Disables the watchdog timer.
42
43 -e Enables the watchdog timer. The timer is not actually started,
44 however, until the timer is reset. The pre-timeout action is
45 not enabled.
46
47 -l Set the watchdog dontLog bit to not log watchdog events in the
48 SEL.
49
50 -p N Set watchdog Pretimeout event action to N. Values: 0 = No
51 action(default), 1 = SMI, 2 = NMI, 3 = Messaging Interrupt. If
52 this is set to an action other than 0, the pretimeout will also
53 be set to 90% of the timeout. However, if the timeout is less
54 than 20 seconds, the pretimeout will not be enabled.
55
56 -q S Set watchdog pretimeout value to S seconds, rather than 90% of
57 the timeout as in -p. The pretimeout value must be >= 5 and at
58 least 5 seconds less than the timeout value.
59
60 -r Resets the watchdog timer. This should be done every N seconds
61 if the timer is running to prevent the watchdog action (usually
62 a system reset) from occurring.
63
64 -tN Set the watchdog Timeout to N seconds. The default is 120 sec‐
65 onds (2 minutes).
66
67 -x Causes extra debug messages to be displayed.
68
69 -N nodename
70 Nodename or IP address of the remote target system. If a node‐
71 name is specified, IPMI LAN interface is used. Otherwise the
72 local system management interface is used.
73
74 -P/-R rmt_pswd
75 Remote password for the nodename given. The default is a null
76 password.
77
78 -U rmt_user
79 Remote username for the nodename given. The default is a null
80 username.
81
82 -E Use the remote password from Environment variable IPMI_PASSWORD.
83
84 -F drv_t
85 Force the driver type to one of the followng: imb, va, open,
86 gnu, landesk, lan, lan2, lan2i, kcs, smb. Note that lan2i means
87 lan2 with intelplus. The default is to detect any available
88 driver type and use it.
89
90 -J Use the specified LanPlus cipher suite (0 thru 17):
91 0=none/none/none, 1=sha1/none/none, 2=sha1/sha1/none,
92 3=sha1/sha1/cbc128, 4=sha1/sha1/xrc4_128, 5=sha1/sha1/xrc4_40,
93 6=md5/none/none, ... 14=md5/md5/xrc4_40. Default is 3.
94
95 -T Use a specified IPMI LAN Authentication Type: 0=None, 1=MD2,
96 2=MD5, 4=Straight Password, 5=OEM.
97
98 -V Use a specified IPMI LAN privilege level. 1=Callback level,
99 2=User level, 3=Operator level, 4=Administrator level (default),
100 5=OEM level.
101
102 -Y Yes, do prompt the user for the IPMI LAN remote password.
103 Alternatives for the password are -E or -P.
