Is the following interpretation correct?
So moving back from HSM to Primary is not advisable.
Adding volumes is ok.
So why would you want to move back? Space and speed considerations..
What to do then?
Create new volume on fast storage, then copy data to new volume, then mount new (fast) volume as old (slow) volume. You can continue this to certain amount of volumes and depending on storage at one time you'll get your data on a san on which you mostly easy can expand your space.
Just wondering whether this is a correct interpretation to remind as a rule of thumb..?
