If some but not all of the Exchange 2007 database volumes are missing and the transaction logs volume and metadata file are available, you can use the snapshot set to perform a roll-forward recovery to the point of failure of the failed volumes. If only one database volume is missing, you can perform a single database restore by using the subComponent=subComponentName attribute in the vxsnap restore command.
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.
Use Exchange to dismount all remaining databases in the storage group.
Delete the missing volumes from Storage Foundation for Windows.
See Deleting missing volumes from Storage Foundation for Windows.
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.
See Recovering the Exchange 2007 storage group to the point of failure .
Refresh the snapshot set.
