27 The reregister command can re-create the logical volume registration,
28 physical volume registration, master directory control segment, and the
29 link to the access control segment.  If the registration data was
30 damaged, the system administrator should be informed so that he can run
31 the register_mdir command or correct any errors in the volume
32 registration.

35 config card) are registered automatically and cannot be registered
36 manually.
