Server cloning: is possible to clone a server using the arrays of another?

  • 772

Scenario:

  • 2 Server HP Proliant recently bought (exactly the same config), below described.
  • EDIT:HP Proliant DL360 G7 (rack form)
  • 4 (500Gb SATA) disks in RAID 10 configuration
    • Array Alfa: Disks of Bays 1&2
    • Array Beta: Disks of Bays 3&4
  • I don't think is relevant, but SO is Windows Server 2008 R2 x64

It's possible that using disks of two arrays (ex.: disks of bays 1 & 3 ) of the Server A to replicate it on Server B ( still non-configured )?

  1. Yep, called mirror-splitting, assuming you have a HP E/P-class controller - just remove (the right) two disks from server1 , replace them with two blanks, that'll then rebuild. Meanwhile boot server 2 from JUST the two disks you removed from server 1, wait for boot to finish (it'll error like crazy) then stick two blanks in server 2 and again wait for rebuild.

    Be aware however that this will not change the server name, IP or SID.

    Yes, this is possible and is a supported and documented process. The term is breaking or splitting and recombining a RAID 1+0 mirror. See HP's documentation and step-by-step instructions for splitting and recombining the array.

    What model of ProLiant are you using? Do you have the details on the controller being used?

  3. If it can't be done using the server RAID, you can use dd on Linux platform to clone disks.

    For Windows, it seems that there is an equivalent one. You can check this out.
