VMS Help ANALYZE, /DISK_STRUCTURE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Analyze/Disk_Structure utility checks the readability and
    validity of Files-11 Structure Level 1 and Structure Level 2 disk
    volumes, and reports errors and inconsistencies.

    You can detect most classes of errors by invoking the utility
    once and using its defaults.

    you specify a volume set, all volumes of the volume set must
    be mounted as Files-11 volumes. For information on the Mount

    Reference Manual.
