Verify that all raw devices that have been in use since the level-0 archive are
available. For example, if you dropped a dbspace or mirroring for a dbspace
since your level-0 archive, you must ensure that the dbspace or mirror chunk
device is available to OnLine when you begin the restore. If the tbtape

you added a chunk since your last archive, you must ensure that the chunk
device is available to OnLine when it begins to roll forward the logical logs.
