Intelligent Pairing vDisk selection decision tree

RecoverPoint/ProtectPoint selects vDisk devices based on a cascading decision tree and is controlled by you.

The following criteria are used:

  • Determine whether there is a unique instance of a Data Domain (DD) disk group name "NsrSnapSG" (or a user-provided name) on the DD, and get its DD pool name as follows:
    • If the user provides the Data Domain pool name.
    • If the ddvdisk pool contains a single disk group, use it, regardless of its name.
    • If the pool contains a NsrSnapSG disk group, use it.
    • Otherwise, fail.
  • If you provide the Data Domain disk group name:
    • Get the list of pools containing this disk group name.
    • If there is 0 or > 1 pool, fail, otherwise, use it.
  • When neither pool nor disk group name is provided:
    • Get the list of pools containing disk group name "NsrSnapSG.”
    • If there is 0 or > 1 pool, fail, otherwise use it.
