 46 # This probe can be viewed as a plugin probe to the agent probe. As such the agent probe performs
 47 # very basic domain checks whereas this plugin probe provides more user specific checks. Currently,
 48 # we only provide private/public key ssh authentication to the guest domain to check either a specific 
 49 # runlevel or SMF service. 
 50 # 
 51 # This plugin probe is passed the following colon separated parameter. 
 52 #
 53 # -P USER:IDFILE:HOST:SERVICE:STATE
 54 #
 55 # USER - User name of user for the prublic key ssh authentication.
 56 # IDFILE - The ssh identity file to read the private key.
 57 # HOST - The guest domain's hostname.
 58 # SERVICE - Either "runlvel" or SMF service.
 59 # STATE - The desired runlevel or online for the SMF service.
 60 #
 61 # For example, 
 62 #
 63 # /opt/SUNWscxvm/bin/ppkssh -P fmuser:/export/fmuser/.ssh/id_dsa:vzodio1a:multi-user-server:online
 64 # /opt/SUNWscxvm/bin/ppkssh -P fmuser:/export/fmuser/.ssh/id_dsa:vzodio2a:runlvel:3
 65 #
 66 # Note that the agent probe passes us a parameter which represents 90% of PROBE_TIMEOUT. As such 
 67 # this plugin probe must complete within that value.
 68 #
 69 # The agent probe will output whatever is output from this plugin probe, e.g.
 70 #
 71 # vzodio1a multi-user-server is online
 72 # vaodio2a runlevel is 3
 73 # 
 74 # The agent probe expects this plugin probe to exit with one of the following return codes.
 75 #
 76 #   0 - Indicates a successful probe.
 77 # 100 - Indicates a complete failure, the agent probe will then attempt to restart the domain.
 78 # 201 - Indicates a complete failure but requests an immeidate failover.
 79 #
 80 # Note that return code 201 requires that the resource has an appropriate value for extension
 81 # properties FAILOVER_MODE and FAILOVER_ENABLED=TRUE. For FAILOVER_MODE refer to the
 82 # r_properties(5) man page.
