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

       /HOMEBLOCKS=option

    This qualifier applies only to Files-11 ODS-2 volumes.

    It specifies where the volume's homeblock and spare copy of the
    homeblock are placed on disk. The value of option can be one of
    the following:

    o  GEOMETRY

       Causes the homeblocks to be placed at separate locations on
       disk, to protect against failure of a disk block. Placement
       depends on the reported geometry of the disk.

    o  FIXED

       Causes the homeblocks to be placed at separate fixed locations
       on the disk; this is the default. Placement is independent
       of the reported geometry of the disk. This caters for disks
       that report different geometries according to which type of
       controller they are attached to.

    o  CONTIGUOUS

       Causes the homeblocks to be placed contiguously at the start
       of the disk. This allows container file systems to maximize
       the amount of contiguous space on the disk, when used with the
       /INDEX=BEGINNING qualifier.
