Coming in via Twitter, @RickSheikh asks me the question “@concentratdgreg Hi Greg. Good refresher on CSV node from http://bit.ly/9RFIiX. At what point do you have a need to copy VHDs to a LUN ?”
Great question, because the reality is that you shouldn’t find yourself using this method all that often. Most CSV volume operations occur within one of Hyper-V’s available tools, such as the Hyper-V Manager or System Center VMM. That said, there is the occasional time when a direct copy may be necessary.
Let me give you a few use cases. Comment below if you know of others:
- Moving a VM from a completely different Hyper-V environment to this one, such as test/dev to production.
- Moving a “golden image”/”reference image” VM from a staging environment to production (or, vice versa).
- Restoring a VM that was backed up using a backup solution which cannot directly replace VMs back to the CSV volume (this is becoming rare).
- Inserting a VM into a Hyper-V environment that was converted from another format, such as .VMDK.
Always remember that such file copies complete the fastest when they’re done through Hyper-V’s coordinator node.
What other use cases do you have? Comment below…
