HPE Storage Users Group

Here is a script I wrote to pause a Cache' database running on a Windows host. It paused the database, snaps the virtual volume and represents back to the operating system to perform nightly backups.

diskpart can be a little flaky and presntation of the volume names can be interesting.

Wanted to thanks those that posted scripts before me, because they really helped me get this working. I'm not really much of a scripting guy.
