Using Host Servers To Create An Initial Snapshot Virtual Disk

  • CAUTION: Before using the Snapshot Virtual Disks Premium Feature in a Microsoft Windows clustered configuration, you must first map the snapshot virtual disk to the cluster node that owns the source virtual disk. This ensures that the cluster nodes correctly recognize the snapshot virtual disk.

    If you map the snapshot virtual disk to the node that does not own the source virtual disk before the snapshot enabling process is completed, the operating system may fail to correctly identify the snapshot virtual disk. This can result in data loss on the source virtual disk or an inaccessible snapshot.

  • NOTE: You can create concurrent snapshots of a source virtual disk on both the source disk group and on another disk group.
Before creating a Snapshot Virtual Disk, note the following:
  • The following types of virtual disks are not valid source virtual disks: snapshot repository virtual disks, snapshot virtual disks, target virtual disks that are participating in a virtual disk copy.
  • You cannot create a snapshot of a virtual disk that contains unreadable sectors.
  • You must satisfy the requirements of your host operating system for creating snapshot virtual disks. Failure to meet the requirements of your host operating system results in an inaccurate point-in-time image of the source virtual disk or the target virtual disk in a virtual disk copy.
