READ the documentation!! The new documents are---- 1. RED20.HLP INTRODUCES YOU TO THE "RED PACK" AND SHOWS HOW TO FORMAT,BUILD,AND CONFIGURE A RED PACK FROM BACK UP TAPES. THIS DOCUMENT ALSO HAS EXAMPLES OF "MIC" FILES. REFERENCE THIS DOCUMENT ON HOW TO RUN "MIC" FILES. 2. REDIAG.HLP SHOWS EXAMPLES OF HOW TO RUN 2020 DIAGNOSTICS. INCLUDES DN22 DIAGNOSTIC EXAMPLES. 3. REDCOM.MEM THIS ONE GIVES YOU INFORMATION ON THE COMMUNICATION HARDWARE AND ALSO EXPLAINS HOW TO RUN DN22 ACCEPTANCE. Some new releases of some old "friends" also are contained in this release. Most of the changes were added to reflect TOPS20 RELEASE 4 and also changes were made to reflect the new "UETP" version. These documents are------------ 1. RED20.MEM THIS REFERENCE MANUAL DESCRIBES THE RED PACK INTERNALS. MUCH WORK WAS DONE TO SUPPORT THE NEW "MIC" FILES AND Page 3 THE NEW VERSION OF UETP. THE "MIC" FILES TAKE THE PLACE OF THE "NEWRUN" FILES ON RED 303!! THERE ARE MANY NEW CONFIGURATION FILES, SO IT IS IMPORTANT TO CAREFULLY LOOK OVER THIS DOCUMENT FOR THE CHANGES!! 2. REDUSR.MEM INCLUDES NEW EXAMPLES OF UETP ACCEPTANCE. NOTICE THE NEW UETP TESTS ADDED. 3. RED20.POL TELLS YOU ABOUT RED PACK POLICIES AND HOW TO ORDER THE RED TAPES 1,3. CHANGED TO REFLECT RED V.404 4. RED20.REV SHOWS VERSIONS OF THE EXEC,MONITOR, AND DIAGNOSTICS. CHANGED TO REFLECT RED V.404. 5. KSREF.MEM ADDED BIT TABLES FOR THE CD11 AND DUP11. ALSO ADDED A TRUTH TABLE FOR CSL EB COMMAND. ----------------------------------------------------------------------------- UETP ---- Major changes were made to this program and new tests were added for SYSTEM ACCEPTANCE. Most of the changes made to "UETP.EXE" were made to make it compatible with TOPS20 RELEASE 4. You'll notice a big difference in the speed of the magtape I/O handling due to release 4 and the UETP magtape tests can now be run with either a large reel of tape (2400 ft.) or a small reel of tape (800 ft.). Also the KMC/DUP loopback tests REALLY WORK NOW!! The new UETP TESTS are--------- 1. DUPA KMC/DUP#0 LOOPBACK TEST 2. DUPB KMC/DUP#1 LOOPBACK TEST 3. DUPAB KMC/DUP#0,1 LOOPBACK TESTS (RUN THIS IF YOU HAVE 2 DUPS) 4. TEST72 USED IN CONJUNCTION WITH THE OTHER LOOPBACK TESTS TO LOOPBACK THE DATA!! NOTE: THESE UETP TESTS REPLACE SNDER1 AND SRVER1 THAT WERE PRESENT ON RED V.303 --- 5. LPT0 PRINTS A "SY ALL" AND "MONITR.STS" AT THE COMPLETION OF A PASS. THIS TEST REQUIRES THAT THE LINEPRINTER REMAIN "ONLINE" DURING ACCEPTANCE. IF YOU DO GET ERRORS RUNNING THIS TEST, GO BACK AND RUN DSLPA!! 6. DN22IN THIS TEST IS FOR 2020 SYSTEMS THAT HAVE DN22 HARDWARE AND MODEM ELIMINATORS. THIS TEST NEEDS DN22OU TO BE RUNNING TO WORK CORRECTLY!! 7. DN22OU THIS TEST IS ALSO FOR 2020 SYSTEMS THAT HAVE DN22 Page 4 HARDWARE AND MODEM ELIMINATORS. THIS TEST MUST BE STARTED FOR DN22IN TO RUN!! KNOWN BUGS IN UETP ------------------ Currently there are some known "flaws" with UETP. These problems were found late in the testing and could not be corrected for this release. There are 2 known bugs in UETP. They are--------- 1. ABORT ALL PROBLEM THIS VERSION OF UETP REQUIRES THAT TWO ABORT ALL COMMANDS HAVE TO BE GIVEN SOMETIMES. IF YOU DO A ABORT ALL OR JUST AN ABORT XXX WHERE XXX IS THE NAME OF THE TEST, DEPENDING ON WHICH STATE THE JOB IS IN THAT YOUR ABORTING, THE TEST OR TESTS MIGHT START BACK UP AFTER YOU HAVE ABORTED THEM. YOU CAN SOLVE THIS BY ABORTING THE JOB AGAIN OR ABORTING ALL OF THEM AGAIN. 2. DSRLST WHENEVER THE UETP TESTS DUPA,DUPB,OR DUPAB ARE RUN WITH TEST72 THIS "BUGINF" MIGHT OCCUR AT THE END OF THE TEST. WITH THE TEST DUPAB, THIS "BUGINF" MIGHT OCCUR TWICE PER PASS. (DSRLST= DATA SET READY LOST) ------------------------------------------------------------------------------ SYSTEM SOFTWARE ------ -------- 1. NEW MONITOR AND EXEC , MONITOR-SUPPORT PROGRAMS Highest visible change: SPEED-improvement !! Nearly all Support programs are now running under SYSJOB . This includes: LPTSPL - the Lineprinter Spooler MOUNTR - the handler for TAPE and STRUCTURE mounting ORION - the message processor QUASAR- the spooling system manager INFO - the inter-job communication handler MAILER - Mail support MAPPER - speedup thru mapping of common programs FAL20 - Network File Access Support STATUS - accumulating DISK and Tape transfer statistics OPER20 - general cleanup and SYSERR-queing every day CDRIVE - Card Reader support SPRINT - Card Batch handler *** Beware : This is the absolute maximum of load SYSJOB can handle Communication and setup for all STRUCTURE , TAPE and QUEING is handled by OPR , running under PTYCON. So if you want to use "OPR" all you have to do is--------- 1. LOGIN F-S 2. ENABLE 3. OPR Now you'll see this output at the CTY. OPR> Page 5 If you would like to see a "STATUS" of the DISK-DRIVES do this OPR>SHOW STATUS DISK-DRIVES ...and wait for the output!! The possibilities are endless!! If your lineprinter for some reason gets "HUNG" it's a good idea to try the following----- 1. LOG F-S 2. ENA 3. OPR OPR>STOP PRINTER 0 OPR>START PRINTER 0 OPR>CONTINUE PRINTER 0 If that doesn't work you can always speak directly to SYSJOB by the ^eSPEAK command and talk to LPTSPL. If all else fails reload the system!! With release of TOPS20 VERSION 4 it is possible to have TAPE LABELING. The RED PACK does NOT have this function enabled. If you do happen to come across a system with this feature, instead of using the ASS MTA0 command, use the "MOUNT TAPE" command. See example. If you want to DUMP the area of the disk to tape try this----- 1. LOAD A WRITE-ENABLED MAGTAPE ON A FREE TAPE DRIVE 2. ENTER THE FOLLOWING @MOUNT TAPE MT:/WRITE-ENABLED AT THIS POINT YOU'LL HAVE TO ISSUE A CNTRL-C (YOUR REQUEST WILL REMAIN IN THE QUEUE) 3. @ENA 4. $OPR 5. OPR>IDENTIFY MTA0: REQUEST X 6. OPR>EXIT 7. $DUMPER 8. DUMPER>TA MT: 9. DUMPER>REWIND 10.DUMPER>SAVE PS:*.*.* PS:*.*.* 11.DUMPER>EXIT 12.@DISMOUNT TAPE MT: To really get familiar with OPR it is advised to do a type out of the Page 6 OPR help file like this--- 1. LOG F-S 2. ENA 3. TYPE PS:OPR.HLP and wait for the output!! KNOWN SYSTEM SOFTWARE BUGS -------------------------- Currently there is one known MONITR BUG. The problem occurs when a 2020 system has 1 KMC AND 1 DUP. The message %NETCON COULD NOT OBTAIN TOPOLOGY MAP will appear on the CTY at system start up!! 2020'S with 1 KMC AND 2 DUPS do not exhibit the problem!! There is also a problem in MOUNTR. If a disk-drive is online during system start up time with bad HOME BLOCKS it might cause a different drive with good HOME BLOCKS to have problems mounting. For example if you have created USER AND USER1 and have another drive online that has not yet been created into a structure(USING CHECKD), it might cause USER or USER1 to have problems when trying to mount those structures!! The way to get around this problem is to take the drive with the BAD HOMEBLOCKS offline, bring the system down then back up. A patch will probably be provided for this problem in the future! PATCHES TO THE MONITOR ---------------------- PROBLEM: Errors on TU77 tape drives can cause TM2CCI and PH2RAE BUGCHKS and KEEP ALIVE errors. THE "RED PACK" HAS BEEN PATCHED TO FIX THE PROBLEM!!
