MOUNTCNT and Ensuring Disks are Cluster-Mounted?

» close window

The Question is:

 
Q: How to obtain the mountcnt of disks
   as shown in SHOW DEVICE (last column)
   not using SHOW DEVICE /OUTPUT etc...
 
Extra info:
 SYS$GETDVI, item DVI$_MOUNTCNT returns only
 0 or 1 depending on the device being mounted
 on the current node or not.
 
any hints for a correct solution?
 
The purpose is to check a system for correctness.
i.e. are devices mounted everywhere in a cluster
are shadow sets valid (correct volumes mounted
on correct disks etc...)
 
 

The Answer is :

 
  There is no direct means of obtaining the MOUNTCNT as displayed by
  SHOW DEVICE, as there is no programming interface to this information.
  The SHOW DEVICE code directly traverses kernel-mode data structures,
  counting up the numbers.
 
  Rather than using the approach that you presently seek, the Wizard
  suggests the use of a site-customized version of the DCL command
  procedure SYS$EXAMPLES:MSCPMOUNT.COM.
