    TITLE:  NCR Chipset & Arcada Backup Exec

    ISSUE

       When attempting to invoke the BESTART command after
       installing Arcada Backup Exec on a Netware file server, the
       server may lock-up.

       To correct directory mirror mismatches, the user may need to run
       the VREPAIR.NLM file after the lock-up.

       This issue affects the Premmia GX and the Manhattan P,V, and G systems.

    BACKGROUND

       According to Arcada Software, there currently is no version of
       Arcada Backup Exec software that includes support for SCSI HBAs
       using any of NCR's SCSI chips.  Although it may be possible to
       get the software to load under certain conditions, it should not
       be considered stable, and therefore should not be used.

    ACTION

       Arcada has informed AST that although there have been a number of
       calls generated by this issue, there are no present plans to
       incorporate NCR SCSI support in their product.

       If an immediate fix is required, perform one of the following
       steps:

       1. Run the backup device from an adapter that is
          supported by the software

          or

       2. Use a software package that includes NCR SCSI support.
