SYMPTOMS

When you restore a clustered disk from a Volume Shadow Copy Service (VSS) transportable snapshot in Windows Server 2008, you have to restore the VSS transportable snapshot to logical unit numbers (LUNs) that are different from the original LUNs. 

For example, in remote failure recovery, you have to re-create the cluster at another site by using the VSS snapshots because the cluster does not exist at this other site. After you create the LUNs from snapshots and bring the LUNs online, the disk resources do not join the cluster.

Note Similar problems can occur in nonclustered situations.

RESOLUTION

After you apply this hotfix, a new input and output control (IOCTL), IOCTL_DISK_RESET_SNAPSHOT_INFO, is available to convert new LUNs that are made from VSS transportable shadow copies. You can use the IOCTL against the new LUNs before you bring them online. Details about IOCTL_DISK_RESET_SNAPSHOT_INFO IOCTL are documented on the Microsoft Developer Network (MSDN) Web site.

Note One side effect of using this IOCTL is that Disk Management tools will now report an additional partition on GPT disks of the type "UNKNOWN." This 256KB partition is created by using the IOCTL and is the Snapshot partition that is used in the restore process. The partition is expected and can be ignored by system administrators.
