Best to use stonith(8): stonith -t external/vcenter VI_SERVER=10.1.1.1 \ VI_CREDSTORE=/etc/vicredentials.xml \ HOSTLIST="hostname1=vmname1;hostname2=vmname2" \ RESETPOWERON=0 -lS or # export VI_SERVER=10.1.1.1 \ VI_CREDSTORE=/etc/vicredentials.xml \ HOSTLIST="hostname1=vmname1;hostname2=vmname2" \ RESETPOWERON=0 # stonith -t external/vcenter -E -lS Another thing, there's an external program ha_log.sh, guaranteed to be in the path, which can be used for logging. Though I can't recall seeing any logging in the plugin, perhaps you should do some. If you use stonith(8) it will print log messages to stdout/stderr. > If everything works correctly you should get: > > hostname1 > hostname2 > > When invoked in this way, the plugin connects to VI_SERVER, authenticates with > credentials stored in VI_CREDSTORE and tries to retrieve the list of virtual > machines (case insensitive) matching vmname1 and vmname2 (and any other > listed). > When finished, it reports the list back by mapping virtual machine names to > hostnames as provided in HOSTLIST.

All or at least most other stonith plugins use lower case parameter names.
