I did look at the help but wasn't too descriptive.. However I did find following bugs on this :
CSCdr70626
Externally found minor defect: Verified (V)
Device Names field is undocumented in Automated Action help
CSCds11921
Internally found severe defect: Unreproducible (U)
Automated action doesnt work on Win2k
CSCdv01267
Externally found moderate defect: Unreproducible (U)
Syslog -> Automated Action -> Advanced -> Pattern not working
I would definitely open a case with TAC, if you are still seeing these failures.. I have filed a bug myself where the first device in the list is missing and the rest of the devices are passed in the main device selection window.. Your seems to be the exactly opposite of that. Hope that helps..
thanks again,
