All,
        We have AIX RS6K/R24 servers, with AIX 4.1.4, each with
        128 gigabytes of SSA disk storage.
        we are having problems allocating large storage volumes on disk.

        We defined 5 logical volumes on the SSA disks, each about 22gb
        Then we tried using DSMFMT to define files as our disk storage
        volumes, each time we allocate above 1 gigabyte we get the
        following message :-
        "error allocating volume errorno = 27"

        We then thought, easy! we'll get around this by allocating
        AIX logical volumes as stg volumes, we used the command :-
        def vol /dev/rxxx, where xxx is the name of the logical volume

        However ADSM only sees these volumes as 980 megabytes each.

        We have been told by Call-AIX that as we use these vols, the
        ADSM "guestimate" of their size will increase, they are actually
        22 gigabytes in size.

        Questions

        How can we ensure that ADSM is actually using all the allocated
        space.
        Is there a better way of doing what we have done.
        Anyone had any similar experiences.

        Thanks,
