If all the database volumes are missing but the transaction logs volume and metadata file are available, you can choose either of the following restore operations:

• Use the snapshot set to restore the mailbox database to the Point in Time (PIT) that the snapshot set was created or last refreshed

• Use the snapshot set to perform a roll-forward recovery to the Point of Failure (POF)

Complete the following tasks to perform a VSS-integrated recovery:

• Identify the snapshot volume associated with each missing production volume. Note the drive letter or mount point of each volume.

  See Identifying the missing volumes (Scenario II).

• Delete the missing volumes from Storage Foundation.

  See Deleting missing volumes from Storage Foundation.

• Replace the failed hardware and add the new disks to the dynamic disk group.

  See Replacing hardware and adding disks to the dynamic disk group.

• Reassign the drive letters or mount points of the snapshot volumes so that they are the same as the missing production volumes.

  See Changing the drive letter or mount points of the snapshot volumes.

• Use the vxsnap restore to recover the databases.
