Hi, Lars
Thank you for your advice.
I decided to use the sbd command with "-W" option to enable watchdog.
It operates well when starting from the command line.
But, I encountered other problem when sbd watch process is started
by Heartbeat using respawn directive in ha.cf.
Start Heartbeat and sbd watch process is OK. The sbd watch process
check shared disk and process messages in the mailbox slot correctly.
But, when Heartbeat is stopped, kernel outputs the following
error message to syslog and the system was rebooted.
(snip)
Sep 9 11:15:56 dl380g5a kernel: SoftDog: Unexpected close, not stopping
watchdog!
(snip)
It seems that the sbd watch process had been stopped
before watchdog_close() was done. And watchdog reboot
the system.

I'm trying SBD that introduced into the latest lha-2.1 repository.
In SBD official document(http://www.linux-ha.org/SBD_Fencing),
watchdog is recommended to be used, but I'm torn between
enable watchdog using sbd watch command option "-W" and
enable watchdog using watchdog directive in ha.cf.
I'd suggest to use the sbd one - that's the one you want to definitely
protect in an sbd configuration.
Please point it out if it is necessary to abolish an existing setting,
and to use sbd watch command with "-W" option.
# Or are both configurations needed?
You cannot use both; in that case, it'd continue running until both
fail, which is not recommended.
Regards,
Lars
