A-5 iv ------------------------------------------------------------ Preface Troubleshooting is the process of isolating and diagnosing problems. When your system does not operate as described in your Operation manual, use the information in this manual to isolate and diagnose the problem. This manual contains three chapters and two appendixes: · Chapter 1 lists problems you may experience at power-up and provides corrective actions. · Chapter 2 lists problems you may experience during normal operation and provides corrective actions. · Chapter 3 tells you how to run the MicroVAX Diagnostic Monitor (MDM), a diagnostic tool you can use to test your system periodically or to isolate a particular problem. · Appendix A contains illustrations showing the location of your system controls and indicators. · Appendix B describes how to write-protect your EF/RF-Series ISE. If the corrective actions suggested in Chapters 1 and 2 do not solve the problem, call your Digital Services representative. The following conventions are used in this manual. ------------------------------------------------------------ Convention Meaning ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Key ------------------------------------------------------------ ------------------------------------------------------------ A terminal key used in text and examples. For example, ------------------------------------------------------------ ------------------------------------------------------------ Break ------------------------------------------------------------ ------------------------------------------------------------ indicates that you press the Break key on your terminal keyboard. ------------------------------------------------------------ ------------------------------------------------------------ Ctrl/C ------------------------------------------------------------ ------------------------------------------------------------ Hold down the Ctrl key while you press the C key. NOTE Provides general information about the current topic. CAUTION Provides information to prevent damage to equipment or software. ------------------------------------------------------------ v 1 ------------------------------------------------------------ Troubleshooting During Power-Up After you turn on your system, the processor performs a series of self-tests and startup routines. After successful completion of the self-tests, if the Break Enable/Disable switch is set to disable (down), your system autoboots system software. 1.1 Autobooting the System Software Your system boots automatically (autoboots) from a specified drive if you have specified a boot device by way of the command SET BOOT device-name from console mode. Your system continues to boot from the specified drive each time it is turned on, until you specify a different device by entering the SET BOOT device-name command again. Your system stores the following console parameters in nonvolatile memory. ------------------------------------------------------------ Parameter Values Comment ------------------------------------------------------------ Language 1 - 15 Sets the language and the keyboard type used under the console ControlP 0,1 (disabled,enabled) Sets ControlP as a halt condition instead of a break, if the break enable switch is set for enable. Halt 0 - 4 (or DEFAULT, RESTART, REBOOT, HALT, RESTART_ REBOOT) Defines the action on halt DSSI_ID Bus 0/A 0 - 7 The DSSI node ID for the CPU DSSI adapter 0 DSSI_ID Bus 1/B 0 - 7 The DSSI node ID for the CPU DSSI adapter 1 Troubleshooting During Power-Up 1-1 ------------------------------------------------------------ Parameter Values Comment ------------------------------------------------------------ DSSI_ID Bus 2/C 0 - 7 The DSSI node ID for the CPU DSSI adapter 2 DSSI_ID Bus 3/D 0 - 7 The DSSI node ID for the CPU DSSI adapter 3 BFLG Hex number up to 8 digits Sets the default R5 boot flag BOOT Boot device Sets the default boot device ------------------------------------------------------------ If ac power is lost, this information is retained. When ac power is restored, type SHOW SAVED_STATE at the >>> prompt. Your system displays these parameters with the values they had at the time of the ac power loss. You can then change any of these values. To boot your system, type B at the >>> prompt. If you do not enter the SET BOOT device-name command, your system boots from the Ethernet port, EZA0. 1.2 Troubleshooting Power-Up Problems Refer to the descriptions of problems and corrective actions in the following sections.

Your system is not configured to see the SCSI ID. Configure your system to see the ID. For example, use SYSGEN AUTOCONFIG on the VMS operating system. The SCSI ID is not unique. Change the SCSI ID and reconfigure the system. The new ID will be effective at the next power-on. The parameters for your SCSI adapter are incorrect. Check your SCSI adapter installation. The SCSI signal cable is loose. Make sure the connector on each end of the cable is fully seated. The SCSI terminator is not present or is loose. Install the terminator; make sure the terminator is fully seated. The SCSI bus is not correctly terminated. If the TZ86 is the last or only device on the bus, make sure the terminator is installed on the TZ86. If the TZ86 is not the last or only device on the bus, check the cable connections and make sure the terminator is installed at the end of the bus. The SCSI terminator is not at the end of the bus, or more than two terminators are present. Be sure to install a terminator at each end of the bus. One terminator is usually installed at the system. The SCSI bus is too long, or too many devices are on the bus. Limit the bus length to the ANSI SCSI standard of 6 meters (19 feet) and the number of devices on the bus (including the system) to eight. Check your system configuration rules. The TZ86 does not power up. The TZ86 has no power. Check the TZ86 power cord connections, with the TZ86 power switch off. All four indicators on the TZ86 front panel blink. A drive fault has occurred. Press the Unload button on the TZ86 front panel to clear the error. If the error does not clear, call Digital Services. 2-10 Troubleshooting During Normal Operation ------------------------------------------------------------ Problem Possible Cause Corrective Action ------------------------------------------------------------ You are finding fatal or nonfatal errors for which you cannot determine the cause. The bus termination or SCSI signal cable connections may be incorrect. Make sure the SCSI bus is terminated. The ac power source grounding may be incorrect. Use an ac outlet for the TZ86 on the same ac line that is powering the system. Failure to mount or read /write with new or used cartridge. Bad cartridge. Retry with another cartridge. Dirty drive head. Use CleaningTape III. VMS INITIALIZE command fails with parity error. Tape calibration failed. Try another cartridge. Green light is on and tape does not move (yellow light stays on, does not blink). Cartridge load error. Inspect the cartridge for a mispositioned leader (refer to Tx86 Series Cartridge Tape Subsystem Owner 's Manual for Diagram of Cartridge Leader). Replace the cartridge if its leader is mispositioned. Inspect the drive for a damaged, misplaced, or unhooked leader (refer to Tx86 Series Cartridge Tape Subsystem Owner 's Manual for Diagram of Cartridge Leader). Call Digital Services if the drive leader is not in the correct position. All four lights are blinking. Drive failed selftest or detected a hard error during operation. Try to clear the error by pressing the Unload button. If the error does not clear (the tape does not rewind and unload and the four lights blink), you have a hardware failure. Call Digital Services. ------------------------------------------------------------ Troubleshooting During Normal Operation 2-11 2.9 TZ87 Tabletop Cartridge Tape Subsystem Problems ------------------------------------------------------------ Problem Possible Cause Corrective Action ------------------------------------------------------------ Your system does not recognize the TZ87.

Change the SCSI ID and reconfigure the system. The new ID will be effective at the next power-on. The parameters for your SCSI adapter are incorrect. Check your SCSI adapter installation. The SCSI signal cable is loose. Make sure the connector on each end of the cable is fully seated. The SCSI terminator is not present or is loose. Install the terminator; make sure the terminator is fully seated. The SCSI bus is not correctly terminated. If the TZ87 is the last or only device on the bus, make sure the terminator is installed on the TZ87. If the TZ87 is not the last or only device on the bus, check the cable connections and make sure the terminator is installed at the end of the bus. The SCSI terminator is not at the end of the bus, or more than two terminators are present. Be sure to install a terminator at each end of the bus. One terminator is usually installed at the system. The SCSI bus is too long, or too many devices are on the bus. Limit the bus length to the ANSI SCSI standard of 6 meters (19 feet) and the number of devices on the bus (including the system) to eight. Check your system configuration rules. The TZ87 does not power up. The TZ87 has no power. Check the TZ87 power cord connections, with the TZ87 power switch off. All indicators on the TZ87 front panel blink. A drive fault has occurred. Press the Unload button on the TZ87 front panel to clear the error. If the error does not clear, call Digital Services. 2-12 Troubleshooting During Normal Operation ------------------------------------------------------------ Problem Possible Cause Corrective Action ------------------------------------------------------------ You are finding fatal or nonfatal errors for which you cannot determine the cause. The bus termination or SCSI signal cable connections may be incorrect. Make sure the SCSI bus is terminated. The ac power source grounding may be incorrect. Use an ac outlet for the TZ87 on the same ac line that is powering the system. Failure to mount or read /write with new or used cartridge. Bad cartridge. Retry with another cartridge. Dirty drive head. Use CleaningTape III. VMS INITIALIZE command fails with parity error. Tape calibration failed. Try another cartridge. Green light is on and tape does not move (yellow light stays on, does not blink). Cartridge load error. Inspect the cartridge for a mispositioned leader (refer to TZ87 Series Cartridge Tape Subsystem Owner 's Manual for Diagram of Cartridge Leader). Replace the cartridge if its leader is mispositioned. Inspect the drive for a damaged, misplaced, or unhooked leader (refer to TZ87 Series Cartridge Tape Subsystem Owner 's Manual for Diagram of Cartridge Leader). Call Digital Services if the drive leader is not in the correct position. All lights are blinking. Drive failed selftest or detected a hard error during operation. Try to clear the error by pressing the Unload button. If the error does not clear (the tape does not rewind and unload and the four lights blink), you have a hardware failure. Call Digital Services. ------------------------------------------------------------ Troubleshooting During Normal Operation 2-13 3 ------------------------------------------------------------ Running the MicroVAX Diagnostic Monitor (MDM) 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 3.2. ------------------------------------------------------------ Caution ------------------------------------------------------------ If your system is connected to a cluster, notify your cluster manager before halting the system to load MDM. ------------------------------------------------------------ You generally run MDM in four situations: · Before you install software on a new system · After you add a device to your system · After you receive an error message or experience a system problem · When you want to test your system periodically to ensure that all components are operating correctly 3.1 MDM Limitations MDM tests internal devices in your system, but it performs limited diagnostics. · MDM reads from each drive and checks each controller, but it does not write to the drives because that could destroy data. Running the MicroVAX Diagnostic Monitor (MDM) 3-1 ------------------------------------------------------------ Note ------------------------------------------------------------ MDM tests a tape or diskette drive only after the medium (tape or diskette) is inserted into the drive. ------------------------------------------------------------ · 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 Services representative for further testing. If you require more complete diagnostic testing, purchase the MicroVAX Maintenance Kit. That kit includes a system maintenance guide and the service diagnostic tests. The MDM version you receive with your system is a subset of the service version. ------------------------------------------------------------ Caution ------------------------------------------------------------ Only qualified service personnel should use the service diagnostic tests. ------------------------------------------------------------ 3.2 Preparing to Run MDM Running MDM on some systems requires additional or special procedures: Read Section 3.2.1 if you plan to run MDM on a diskless or tapeless system. Read Section 3.2.2 if you plan to install MDM on a hard disk or RF-series Integrated Storage Element. Read Section 3.2.3 if you plan to run MDM on a DSSI VAXcluster. You can run MDM on an RRD-series disc drive by using the MDM CDROM Kit. 3.2.1 Preparing to Run MDM on a Diskless or Tapeless System To run MDM on a diskless or tapeless system that is part of a local area network, you must: · Obtain a MicroVAX Ethernet Server Customer Diagnostics Kit. · Run MDM using the diagnostics in that kit, labeled MV DIAG ENET CUST. 3-2 Running the MicroVAX Diagnostic Monitor (MDM) 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. To diagnose problems, call your Digital Services representative. ------------------------------------------------------------ 3.2.2 Preparing to Run MDM on an EF/RF-Series Integrated Storage Element (ISE) or Hard Disk You can install MDM on an EF/RF-series ISE or hard-disk drive by using the MDM Hard Disk Kit. Installation of that kit requires your completion of the Diagnostic Software Installation Acknowledgment. See the MicroVAX Diagnostic Monitor Hard Disk User 's Guide for licensing requirements and installation instructions. 3.2.3 Preparing to Run MDM on a DSSI VAXcluster ------------------------------------------------------------ Note ------------------------------------------------------------ The MDM Hard Disk Kit is required for a two-system DSSI VAXcluster where one host is a tapeless system, and the other uses the TK70 tape drive. TF-series tape drives are DSSI devices and can be shared between systems in a DSSI VAXcluster. Both systems in a two-system DSSI VAXcluster can boot MDM from the same drive, However you must run MDM separately from each host. ------------------------------------------------------------ Before running MDM: · Your system must be properly configured. · The Digital Storage Systems Interconnect (DSSI) cable connecting the multiple hosts must be installed. You must run MDM separately for each host. For TK70 based systems, the procedure to use depends on whether one host is a tapeless system (no tape drive) or each host has its own tape drive. Use the procedure in Section 3.2.3.1 to prepare to run MDM in a DSSI VAXcluster with one TK70 tape drive. Running the MicroVAX Diagnostic Monitor (MDM) 3-3 Use the procedure in Section 3.2.3.2 to prepare to run MDM in a DSSI VAXcluster with a TK70 tape drive in each host. 3.2.3.1 MDM on a DSSI VAXcluster with One TK70 Tape Drive To run MDM on a DSSI VAXcluster with one TK70 tape drive (one or more tapeless hosts): · Use the MDM Hard Disk Kit. · Complete the Diagnostic Software Installation Acknowledgment. · Install the kit on a hard disk or an EF/RF-series ISE as described in the MicroVAX Diagnostic Monitor Hard Disk User 's Guide.

For all 3.5-inch drives, you write-protect an ISE by setting the Write-Protect button to in (lit). For the EF/RF ISE, which has no Write-Protect button, you set write-protection through VMS commands or through firmware commands in console mode, explained later in this section. The Write-Protect button controls whether the system can write data to the ISE. The system can read from the ISE regardless of the setting of the Write-Protect button. When the Write-Protect button is out (not lit), the system can write to the ISE. Your system disk (the ISE containing system software) and ISEs containing work areas for users should be write-enabled, the normal operating setting. B.1 Software Write-Protect for EF/RF-Series ISEs Since the EF/RF does not have a Write-Protect button, the software write-protect is the primary method for write-protecting an EF/RF. The software write-protect is available through VMS using the MOUNT utility with the /NOWRITE qualifier. To software write-protect an ISE, enter the following DCL command from the VMS operating system. MOUNT /SYSTEM/NOWRITE where is the device name, as shown using the VMS DCL command SHOW DEVICE DI, and is the volume label for the device. For example, $ MOUNT $1$DIA1 OMEGA/SYSTEM/NOWRITE will software write-protect device $1$DIA1. Write-Protecting an EF/RF-Series ISE B-1 Dismounting, and then remounting the device (without using the /NOWRITE qualifier), will write-enable the device. Use the VMS DCL command SHOW DEVICE DI to check the protection status of the drive. A write-protected drive will show a device status of Mounted wrtlck. Refer to your VMS documentation for more information on using the MOUNT Utility. ------------------------------------------------------------ Caution ------------------------------------------------------------ When you dismount then mount the device again, it will no longer be write-protected. ------------------------------------------------------------ B.2 Hardware Write-Protect for EF/RF ISEs The hardware write-protect provides a more permanent write-protection than the software write-protect in that once you hardware write-protect an EF/RF it remains write-protected regardless of the availability of the operating system or if the system is powered-down. In addition, a hardware write-protect cannot be removed using the MOUNT command. The hardware write-protect simply provides the same degree of write-protection available to EF/RF-series ISEs that have a Write-Protect button. You should consider hardware write-protecting an EF/RF in the following situations. · If you want to write-protect an EF/RF ISE when the VMS operating system is not available, such as before running the MicroVAX Diagnostic Monitor (MDM). · If you want to ensure that an EF/RF remains write-protected, since the hardware write-protect cannot be removed using the VMS command MOUNT and will remain in effect even if the operating system is brought down. You can hardware write-protect an EF/RF from VMS or through firmware commands entered at the console prompt (>>>). Use the following instructions. 1. Access the Diagnostic and Utility Program (DUP) driver for the device you want to write-protect. · To access the DUP driver from console mode: a. Enter console mode by pressing the Halt Button or powering up the system with the Break Enable/Disable switch set to enable (up, position 1). B-2 Write-Protecting an EF/RF-Series ISE ------------------------------------------------------------ Caution ------------------------------------------------------------ Halting your system without following the shutdown procedure described in your system software manuals may result in loss of data. ------------------------------------------------------------ b. Access the DUP driver by setting host to the specific device you want to write protect. Use the following command for embedded DSSI. SET HOST/DUP/DSSI/BUS: PARAMS where is the DSSI bus number (0,1,2,3), and is the bus node ID (0-6) for the device on the bus (bus number and node number are listed in the SHOW DSSI display). Use the following command for KFQSA-based DSSI. SET HOST/DUP/UQSSP/DISK PARAMS where is the controller number (listed in the SHOW UQSSP display) for the device on the bus. · To access the DUP driver from VMS: a. Connect to the Diagnostic and Utility Program (DUP) and load its driver using the VMS System Generation Utility (SYSGEN) as shown below. $ MCR SYSGEN SYSGEN> CONNECT/NOADAPTER FYA0 SYSGEN> EXIT $ b. Access the DUP driver by setting host to the specific device you want to write protect. Use the following command. SET HOST/DUP/SERVER=MSCP$DUP/TASK=PARAMS where is the device node name (the node name, in parenthesis, is listed in the SHOW DEVICE DI display). 2. At the PARAMS> prompt, enter SET WRT_PROT 1 to write-protect the ISE to which you are currently connected. ------------------------------------------------------------ Note ------------------------------------------------------------ To verify that you have set host to the intended drive, you can enter the command LOCATE at the PARAMS> prompt. The LOCATE command causes the drive's Fault indicator to blink momentarily. ------------------------------------------------------------ Write-Protecting an EF/RF-Series ISE B-3 3. Enter SHOW WRT_PROT to verify the WRT_PROT parameter is set to 1. 4. After you have completed setting and examining the WRT_PROT device parameter, enter the WRITE command at the PARAMS> prompt to save the device parameter. The change is recorded to nonvolatile memory. 5. Enter the EXIT command at the PARAMS> prompt to exit the DUP driver utility for the specified device. This is an example of setting a hardware write-protect through firmware. >>>SET HOST/DUP/DSSI/BUS:0 1 PARAMS Starting DUP server... Copyright (c) 1992 Digital Equipment Corporation PARAMS>SET WRT_PROT 1 PARAMS>WRITE PARAMS>SHOW WRT_PROT Parameter Current Default Type Radix --------- ---------------- ---------------- -------- ----- WRT_PROT 1 0 Boolean 0/1 PARAMS>EXIT Exiting... Stopping DUP server... >>> This is an example of setting a hardware write-protect through VMS. $ MCR SYSGEN SYSGEN> CONNECT/NOADAPTER FYA0 SYSGEN> EXIT $ SET HOST/DUP/SERVER=MSCP$DUP/TASK=PARAMS R35F3C Starting DUP server...

Stopping DUP server... $ To remove the hardware write-protection, repeat the above procedure, only set the WRT_PROT value to 0. B-4 Write-Protecting an EF/RF-Series ISE You can verify that the device is write-protected while running VMS--when you issue the VMS DCL command SHOW DEVICE DI, a write-protected drive will show a device status of Mounted wrtlck. If you issue the VMS command SHOW DEVICE/FULL, a write-protected drive will be listed as software write-locked. ------------------------------------------------------------ Note ------------------------------------------------------------ You cannot remove hardware write-protection using the VMS MOUNT utility. ------------------------------------------------------------
