The recommended way to change parameters in the configuration file for ILOM watchdog and host watchdog is to use the ilomconfig command with the ilomwatchdog or hostwatchdog targets. Use this procedure only if you are not able to use the ilomconfig command.
/etc/ssm_directory/hmp_watchdogd.conf
Where ssm_directory is either sun-ssm or ssm, depending on your version of Oracle Hardware Management Pack.
ilom_watchdog_admin_state=value
ilom_watchdog_number_sp_reset=value
ilom_watchdog_timer_action=value
ilom_watchdog_query_time_interval=value
host_watchdog_admin_state=value
host_watchdog_timer_action=value
host_watchdog_timer_value=value
host_watchdog_reset_period=value
See ILOM Watchdog Parameters and Host Watchdog Parameters for information on defaults and available values for each parameter.
