    1.2 Diagnostic Tests and Commands There are a number of diagnostic tests and commands that can help you to isolate a problem with the system unit. These tests and commands are as follows: • Power-up tests • Self-tests • Configuration display •...

  • Page 14: Power-Up Tests

    1.2.1 Power-Up Tests The system runs the power-up tests each time you turn on the system. If the system passes the tests, it responds with a display similar to the following example: KA52-A V1.1, VMB 2.14 Performing normal system tests. 72..71..70..69..68..67..66..65..64..63..62..61..60..59..58..57..

  • Page 16: Self-Tests

    1.2.2 Self-Tests Self-tests perform the same tests as the power-up tests except for one difference; the power-up tests test all the devices in the system, whereas the self-tests allow you to test a single device. Execution of the SHOW CONFIG command produces the display showing the failure of the device DZ.
  • Page 17 In the example in this section, the show configuration display shows the the DZ device has failed. The self-test number for this device is E4. See Example 1–2 . Test E4 should be run by entering T E4 at the console prompt.

  • Page 23: Running The Diagnostic Monitor

    Running the Diagnostic Monitor The MicroVAX Diagnostic Monitor (MDM) is an optional software package containing diagnostic tests that isolate and identify faults in your system. MDM also lets you display your system configuration and test how devices work together. MDM is on tape, in a cartridge labeled MV DIAG CUST TK50. MDM operating instructions begin in Section 2.2.

  • Page 24: Preparing To Run Mdm

    • MDM checks devices on the system as well as the system and interconnects. • MDM checks terminal interfaces (but not terminals) by means of feedback connectors. If your devices pass the tests but you still experience problems, call your Digital service representative for further testing.

  • Page 25: Preparing To Run Mdm On An Rf-Series Integrated Storage Element (Ise) Or Hard Disk

    Refer to the MicroVAX Diagnostic Monitor Ethernet Server User’s Guide at this time. After you install and downline load MDM, refer again to that manual for instructions on running MDM. Note If you have a diskless or tapeless system that is not part of a local area network, you cannot run MDM.

  • Page 26: Mdm On A Dssi Vaxcluster With One Tkxx Tape Drive

    Use the procedure in Section 2.2.3.2 to prepare to run MDM in a DSSI VAXcluster with a TKxx tape drive in each host. 2.2.3.1 MDM on a DSSI VAXcluster with One TKxx Tape Drive To run MDM on a DSSI VAXcluster with one TKxx tape drive (one or more tapeless hosts): •...

    Run MDM as you did for the first system. 2.2.3.2 MDM on a DSSI VAXcluster with Two TKxx Tape Drives To run MDM on a DSSI VAXcluster with two tape drives in each system: Note You can also use the MDM Hard Disk Kit as described in the previous section.

  • Page 28: Starting Mdm

    2.3 Starting MDM You must start MDM differently for different media: If you are booting MDM from a tape drive, read Section 2.3.1. If you are booting MDM from an RRD-series disc drive, read Section 2.3.2. If you are booting MDM from a hard disk or an RF-series ISE, refer to the MicroVAX Diagnostic Monitor Hard Disk User’s Guide.

  • Page 29: Booting Mdm Manually

    2.3.1.1 Booting MDM Manually Use this procedure to boot MDM from a TF-series, TK50 or TK70 tape drive. 1. If software is installed on your system: a. Warn all users to log off. b. Perform system shutdown as described in your software manuals. 2.

  • Page 30: Rrd-Series Compact Disc Instructions

    4. Remove any removable disks, and place all fixed-disk drives and RF-series ISEs off line. 5. Write-protect all disk drives and RF-series ISEs. 6. Turn off your system. 7. Set the Break Enable/Disable switch to disable (down). 8. Turn on your system. 9.

  • Page 31: Mdm Introductory Display

    7. Tell your system to load MDM from the disc: For an internal adapter, enter the command BOOT DKxnnn, where x is the adapter designator and nnn is the drive unit number. For a KRQ50 controller, enter the command BOOT/100 DUcu, where c is the controller designator and u is the drive unit number.

  • Page 32: Test The System Option

    Select an option by typing its number and Return The next six sections describe the options on the Main Menu. 2.5.1 Test the System Option The Test the System option tests the devices it sees in your system and how they work together.

  • Page 33: Display System Configuration And Devices Option

    OPTION: SGCA Ethernet controller The Field Replaceable Unit (FRU) identified is the: Ethernet controller If your system has serious problems, the following message appears. All devices disabled, no tests run. Report that message to your Digital service representative. After a failure message appears, the testing stops. After all devices pass the first part of the test, the exerciser tests begin.

  • Page 36: Ioaddres Function

    Note If your system does not have an RRD-series drive connected to a KRQ50 controller, only one function, IOADDRES, is available. Select a function by typing its number and pressing Return 2.5.3.1 IOADDRES Function Note The IOADDRES function is for users of Industrial VAX systems. It is described in the Industrial VAX troubleshooting manual.

  • Page 37: Display The Connect/Ignore Menu Option

    2.5.5 Display the Connect/Ignore Menu Option Note The Connect/Ignore Menu is for users of Industrial VAX systems. Its options are described in the Industrial VAX troubleshooting manual. The Display the Connect/Ignore Menu option lets you customize MDM diagnostics. You can load your own diagnostics as well as MDM diagnostics on a device with a nonstandard CSR address and interrupt vector.
  • Page 38 Note Because of the similarity of some communication options, MDM sees them as the same device. A CXA16 and CXB16 appear the same to MDM. A generic device name, DH–CX0, is listed for such options, and the last letter in each name shows the difference. For example, DH–CX0A indicates one option, DH–CX0B a second, and so forth.
