1.  Release Abstract

    The @50V14 microcode file is for use with the 50V14 RSF Fiber Optic (FDDI)
    Resource Sharing Facility I/O controller product.  This can be installed
    in any of the VS 5000 or 6000 series minicomputers.

    This microcode supports the RSF protocol and is functionally equivalent to
    the 70V14 RSF product.

    This microcode supports a maximum of 8 physical stations.


2.  Prerequisites & Dependencies

    2.1  Hardware Prerequisites

    VS 5000 or 6000 series minicomputer.


    2.2  Software Prerequisites

    VS OS release 7.53.00 or later is required for the support of this product
    and all systems in the cluster must be at the same Operating System level.

    If any @70V14 IOCS (high end VS systems) exists in the cluster the @70V14
microcode must be at a minimum revision of 3.01.00.


3.  Restrictions and Special Considerations

    All systems must upgrade the RSF microcode at the same time in order for
    the cluster to function properly.  All systems in the cluster MUST be at
    the same VS OS level.


4.  Enhancements

    Version 3.01.00 is the first release of @50V14 microcode.


5.  Problems Corrected

    Version 3.01.00 is the first release of @50V14 microcode.


6.  Known Anomalies

    When an attached cluster node is re-ipled without first detaching it may
    not attach on the first attempt after IPL.  A manual detach and attach
    sequence will correct the problem.
