        DIAGNOSTIC INFORMATION
        ----------------------

          Running Online Diagnostics on Version 5.3.0.30

            To run Online Diagnostics, the bos.diag package
            must have been previously installed.  The
            packages for the devices that you wish to test should
            also have been installed.

            If a device does not show up in the test list or you think
            that a device's Diagnostic package may not have been loaded,
            you can check by using the lscfg command.  At an AIX prompt,
            type lscfg.  If the device which you were wanting to test
            has a '+' or '-' preceding its name, the package was loaded.
            If the device has a '*' in front of its name, it means that
            the device is not testable by diagnostics.

        Firmware needed to Run 5.3.0.0 & above Standalone Diagnostics

             If the system was release prior to 2004, then update the
             system firmware to the most recent available level in order
             to boot 5.3.0.0 & above levels of standalone diagnostics.
             Systems listed should be updated with the firmware
             image listed prior to booting standalone diagnostics versions
             5.3.0.0. and above (higher firmware levels are acceptable).
             This is not a complete list.  Alternatively, standalone
             diagnostics version 5.2.0.30 or 5.2.0.35 will run on supported
             systems at a firmware level lower than this minimum firmware
             level listed.

                                                                        5



        Enhancements Supported by Diagnostics Version 5.3.0.30



               - Diagnostics supports new format physical location codes
                 up to  a maximum length of 79 characters.  These location
                 codes  can be identified by the presence of a unit
                 identifier that  is composed of the machine type, model and
                 serial number.   For example, a system with machine type
                 9117, model 250, and  serial number 10-ABCDE will have
                 location codes that begin  with the string
                 "U9117.250.10ABCDE".  In addition, some of the physical
                 location code standard prefixes are different for the new
                 format physical location codes than for the "shorter format"
                 physical location codes.

                 Systems introduced in August 2004 and later will use this new
                 format physical location code.  Systems introduced prior to
                 August 2004 will use the existing "shorter format" physical
                 location codes.  See the "Diagnostic Numbers and Location
                 Codes" chapter in the service documentation for more
                 information. The new format physical location codes are
                 shown in diagnostics level 5.2.0.30 and higher.


                 For these new format physical location codes, most
                 diagnostic menus will have a slightly different format.  The
                 biggest difference is the resource selection menu.  It will
                 show the unit identifier only once for each unit or
                 enclosure, with each of the resources in that unit or
                 enclosure listed immediately following the unit identifier.

               - Automatic Error Log Analysis and Notification service aid.
                 This service aid contains functions taken from the Periodic
                 Diagnostics service aid.  These functions include the
                 ability to configure an error notification mailing list and
                 to disable or enable automatic error log analysis.  Systems
                 or partitions containing only virtual or shared processors
                 will not display the Periodic Diagnostics service aid.

               - Update and Manage System Flash Task.  This task validates
                 a new system firmware flash image and uses it to update the
                 system temporary flash image.  This task can also be used to
                 validate a new system firmware flash image without
                 performing an update, commit the temporary flash image, and
                 reject the temporary flash image.  For systems that support
                 the Update and Manage System Flash Task, this task appears
                 in place of the Update System and Service Processor Flash
                 Task. On Power 5 systems with an HMC, this task may not
                 appear on the task list; on these systems use the HMC to
                 update system flash. 

               - Diagnostics support for IDE DVD-RAM.  The IDE
                 DVD-RAM Diagnostics service aid includes format, certify
                 media, display microcode and download microcode.

               - Support for loading microcode and supplemental media from
                 optical media.

               - Running standalone diagnostics from CDROM media now
                 permits removal of the diagnostics CDROM media from the
                 optical media drive while running standalone diagnostics
                 on systems or partitions with 256MB of memory or greater.
                 This permits the use of the same optical media drive for
                 loading both standalone diagnostics and microcode.

               - Support for self-configuring ATAPI optical devices.

               - The Configure Reboot Policy Task was updated to support 
                 the platform-auto-power-restart parameter for POWER 5 systems.
