    * PROBLEM DESCRIPTION: d tcpip,,LUNS,OBJECT commands           *
    *                      cause overlays which lead to            *

    ****************************************************************
    The problem may be summarized as follows:
    1. The LUNRs in the LUNS/LUNR configuration
       each have a large number of ports.
    2. A d tcpip,,LUNS,OBJECT  command is issued.
    3. While constructing an internal worklist related
       to the LUNRs, the worklist array is exceeded and
       an overlay results.
    4. The abend that will occur depends on what storage
       is overlaid.  Abends have been seen in EZBTDOBJ.

Problem conclusion

  • EZBTMCTD has been updated to restart building entries
    at the start of the workarea when processing a new
    LUNR's ports.
    
    EZBTXLUS and EZBTXLUR have been included for maintenance
    purposes.
