STOP REBOOT is  not enough, you must  NODESGEN WTONLY if you  use PUTC. PUTC
basically does what  a R/W link to  the disk followed by a  COPYFILE would do.
And the nodes table generation process is not invoked at re-IPL time.
 
  PUTALL acts as a PUT with FAC  validation overriden and will invoke the File
Access Validation  exit which, in our  case, issues a NODESGEN  WTONLY command
itself. The  password required is  that associated with  the FAC of  the first
filelist up the tree structure that you were allowed to PUT, ie the CTL FAC in
our case. CTL maps to "any postmaster" including cc ones, so it should require
the createpw which all postmasters are supposed to know.
