DPM 2012 - converting pass-through disk to fixed size VHD and DPM RRS feed

  • Question

  • Our Sr. Admin is attempting to convert our Exchange 2010 pass-through disk to fixed VHD and found that our 2008 R2 Hyper-V clustered environment won't allow him to storage migrate a VM when it has any pass-through disk.  He is formulating the next plan and since I'm responsible for DPM he is asking some questions.  We see posts where people complained that after converting pass-through to VHD they couldn't backup with DPM because the disk signature was the same but DPM expects it to be a different/new disks.  He is suggesting "having to create a new Exchange MB VM's using VHDs, add to the DAG, then add DB copies and remove the copies on the old VM with the pass-thrus and then remove the old VM.  This option is actually not that bad and I suspect we'll end up going this route because its the most well udnerstood and trustable way to do it." 

    We wonder if we'll run into DPM not liking the Exchange DB being on a disk with a different signature?  Will this cause, if it works, DPM to want to backup the entire DB. Its rather large.

  • I am marking this resolved for house cleaning and also moving to our general forums since this is storage related
