During the process of refreshing the snapshot set any volumes that were originally snapshot volumes of missing production volumes will become master (production) volumes. These volumes currently reside on the disks on which the original snapshot volumes were created.
Perform the following tasks to move the master (production) volumes to different disks:
Snap back the snapshot transaction logs volumes if you recovered using a roll-forward recovery to the point of failure.
Additionally, snap back the snapshot volumes of any databases that were not affected by the disk failure (and thus still have snapshot volumes associated with them).
Snap clear each volume in the snapshot set whose drive letter or mount point was reassigned prior to the restore process. The snap clear removes the association of the snapshot volume with the original production volume.
Add a mirror to each volume in the snapshot set whose drive letter or mount point was reassigned prior to the restore process. For each new mirror (plex), choose the disks where you want the production volumes to reside.
Prepare each of the new mirror volumes and convert an existing mirror into a snap plex. Choose the mirror that was the snapshot volume of the failed production volume as the new snapshot mirror (snap plex).
Use the vxsnap create command to create a new snapshot set of all the volumes in the mailbox database.
