Add disk RRS feed

  • Question

  • Hi,

    I have 2 2008 r2 physical servers connected to a SAN. On those servers are multiple 2008 r2 servers. The focus is to have a high availability environment. Therefore i am using the high availability clustering feature fo 2008 r2.

    Everything working fine & I can live migrate virtual servers between physical servers.

    I have just installed DPM 2010 & am trying to work out how to add a disk that will be used for the back ups that DPM will do.

    Ive created a drive on the SAN with raid 5 but not sure how to get it to the virtual DPM server.

    Should it be a clustered volume?

    It obviously needs to be available to the DPM virtual server no matter what physical server DPM is working on.

    Any assistance would be greatly appreciated.

    Thanks in advance

  • Hi,

    That's a possibility but I kinda misformulated what I meant.  What I mean is, create a secondary drive onto the Virtual DPM server, and use space from the CSV.  That way you get a second drive VHD, within the CSV and then DPM remains high-available

    Cheers

    PS: I would advise to create a physical DPM server with JBOD if you take this into production.  The performance will be better and in the "worst case scenario" you will be able to recover much easier

  • Hey,

    When you are running DPM virtual, you have a few options.  You can add pass-through disks, jbod, vhd and so on...

    If you want to be sure that the DPM server can failover then present the lun as a vhd to the DPM server.  That will work just fine.  My demo / test environment runs like that without any problems.

    Just my 2 cents

    Cheers,

    Mike

    Can you advise how to do this?

  • Hey,

    Add the lun as a VHD onto your virtual machine.

    Start the virtual machine, and let the disk be "discovered" by windows.

    Leave it unformatted (DPM needs RAW disk).  Go to the DPM UI, and go to Management and then Disk.  Add a disk over there, and it should see the RAW vhd.

    Cheers,

  • Hi Mike,

    Not 100% sure what you mean by Add the lun as a VHD onto your virtual machine.

    My interpretation create a clustered shared volume off of the raid 5 disk created on the san, then add a vhd onto it then add this as a secondry drive on the Virtual DPM Server

    Is this correct?

    Thanks again
