  Per-Disk Volume Shadowing Licenses? 
 The Question is:
 
Will a Volume shadowing per Disk License (ql-2a1aa-3b) work on Vms Ver 55.2h4
 
 The Answer is:
 
  V5.5-2H4 is simply too old and does not include support of the
  per-disk volume shadowing licenses -- you need OpenVMS VAX V6.1
  or later for the per-disk volume shadowing licenses.  With releases
  older than OpenVMS V6.1, the full product license is required.
