Delete .taf files when server crashes?

5.6 on HP UX.  We have rather old instructions from McKesson about clean up steps if Cloverleaf goes down ungracefully like following a major hardware-related crash (something that’s happened to us twice in the last several weeks).  There’s a line in that document that says to go to $HCISITEDIR/exe/databases and delete the vista.taf file.  We don’t see a vista.taf in that directory but we do see an rdm.taf.  Is rdm.taf the same as vista.taf and, if it is, is it a good idea to delete it under these circumstances?  We didn’t either time and managed to get all of our processes going but I still wonder if it’s not a bad idea.
