Procedure to Follow When Frankenheim Has a Problem When there are problems with Frankenheim, do the following to help Bill diagnose the problem so he can determine if the problem is hardware or software. Make a note of the contents of the Frankenheim monitor. What windows are there? Is part of the screen black? If the computer is logged in as OBS and the screen has no black, will it open a window (such as the Greg or Chef window) where there's a command prompt? If so, type SHOW ERROR and record the results. Also type SHOW SYSTEM and either record the results or call Bill and read them to him. If the login screen is there, can you log in as OBS? (If so, skip the following and call Bill.) If the screen is partially black, there's probably a >>> prompt in there somewhere. Press a few times to find it and scroll off enough of the screen to get the prompt on a blank line. Then type SHOW DEVICE and record the results. Next, type B to boot the machine. (This should clear the screen and print DKA0 in the upper left corner. After a minute or less you should see some output from the Boot Script.) If the screen was NOT partially black, but the computer is unresponsive, force a crash dump, using the following procedure from Compaq/Digital: 1. (Not Applicapable) 2. Stop the system by pressing the HALT button (recessed in the center hole of those on the right side of the Pizza Box near the back). This should produce a >>> prompt. Strike if necessary to scroll the screen to where the prompt is on a blank line. 3. Examine and record the processor registers by entering the following commands: >>> E/I 0 ! Examine Stack Pointers - Kernel >>> E + ! - Exec >>> E + ! - Super >>> E + ! - User >>> E + ! - Interrupt >>> E/G/N:F R0 ! Get contents of R0-R15 4. Examine and record the PC (Program Counter) and PSL (Processor status Longword) and place the system back in its original hang condition: >>> E/G F ! Get the PC >>> E PSL ! Examine PSL to determine IPL level >>> C ! Continues the hang condition 5. Repeat steps 1, 2, and 4 for at least 5 iterations, omitting the ">>> C" (Continue) command in the 5th iteration. (N.B., you can skip step 3 in these iterations.) Note: Since Frankenheim is a member of a VMScluster, a CLUEXIT bugcheck may occur during this step. Do not become concerned, this is expected. Simply let the system continue to write to the dumpfile. If not, proceed with step 6. 6. Deposit an invalid value in the PC and direct the system to begin execution on the interrupt stack at the highest IPL (Interrupt Priority Level), 31: >>> D PC FFFFFFFF ! Invalid value in the PC >>> D PSL 041F0000 ! Interrupt stack, IPL 31 >>> C ! Force an INVEXCEPTN Bugcheck This step will cause the contents of memory to be written to the dumpfile followed by an automatic system reboot. If the system does not automatically reboot, you must boot it manually. See the "Installation and Operations Guide" for instructions.
