  API for shadow copy and mount count info? 
 The Question is:
 
Questions on how to query system information programmatically. If the OS can
 show it on screen, there must be a better way (DCL or system service call)
 than parsing the screen output.
 
1. Device mount count, i.e. the number in the last column from SHOW DEVICE. Is
 lexical F$GETDVI(device, "MOUNTCNT") supposed to do this job? It always return
 1 to me.
 
2. Shadow copying / merging percentage complete. I don't find anything other
 than true or false of copying / merging.
 
 
 
 
 The Answer is:
 
  There is no documented API available for the cluster-wide mount
  count displayed by SHOW DEVICE, only an API for acquiring the
  node-specific mount count.  There is also no documented API
  available for reporting the shadowing completion percentage.
