A.1.4 Setting up Watchdog Power Switches
A description of the usage model for watchdog timers as a cluster data integrity provision appears
in Section 2.1.3, Choosing the Type of Power Controller. As described in that section, there are two
variants of watchdog timers: Hardware-based and software-based.
The following details the configuration tasks required in order to setup watchdog timer usage in a
cluster hardware configuration.
Regardless of which type of watchdog timer is employed, it is necessary to create the device special
file appropriate for the watchdog timer. This can be accomplished as follows:
# cd /dev
# ./MAKEDEV watchdog
When running the cluconfig utility, where it prompts for the power switch type, specify a type of
SW_WATCHDOG, regardless of the specific type of watchdog timer in use.
