PROBLEMS/SYMPTOMS: Continued from Page 1.
-----------------------------------------
SOLUTION SUMMARY - L0118 DESIGN AND L0100 E* ECOS
# - Denotes changes incompatible with L0100-D1, or CIBCA
"7-tick DELTA-TIME mode; and controlled by "COMPATIBILITY
7/10-tick" switch on L0100-E1/E2 or L0118.
1.# BASIC QUIET-SLOT extended from 7 to 10 ticks (tick=byte=114 ns.,
change = 800 ns. to 1140 ns.) to fix adjacent node collision
problem at 40% CI-path utilization caused by L0100 Tx-start/Rx-
detect logic delays when such nodes simultaneously arbitrate.
2.# HIGH/LOW-PRIORITY (Round-ROBIN) ARBITRATION COUNTER logic fixed
to prevent "false BEATEN-BY-NODE-0" detection during ACK-
TURNAROUND carrier-delay, resulting in biasing arb-wins to
low-nodes. Fix requires QUIET-SLOT change, and must be
applied to all L0100 to prevent arbitration biasing.
3. # EXTEND ACK-TURNAROUND TIME (INFO-to-ACK PACKET delay) to
ensure CI-sender (INFO-PKT) ready to receive ACK, under
worst-case (short,fast) propagation delays, such as with
SC004 (dual-CI750) and short-CI-cables (6-10 meter).
Fix requires QUIET-SLOT change.
4. Fix SYNC-DETECT "PAL" to prevent lock-up during CI-carrier
"flood", an infrequent CI-LINK failure mode.
5. EXTEND "TRAILER TRANSMIT TIME" to ensure at least 5 bytes
of trailer (after CRC) sent, instead of 3.5 bytes.
6. EXTEND HEADER JUMPER (not used in current CI applic.) was
non-functional: Fix.
7. ALTER-DELTA-TIME JUMPER (7/16-tick quiet-slot) was
non-functional: Fix. Not currently used, but intended
for extended CI-cabling lengths, or fiber.
8. ARBITRATION STATUS REPORTING enhanced to distinguish
ARB-TIMEOUT from "fail to xmit after successful ARB".
9. CI20 ONLY: CRC-COUNT RESET failed on SELF-DIRECTED
packets: Fix.
10. MISCELLANEOUS L0100 Print-Set logic-drawing clean-up,
marginal logic-design improvement, for benefit of
future CIxxx chip-designs (CIBCA...) based on L0100.

CI-LINK MODULE FCO INSTALLATION SUMMARY
---------------------------------------
**********************************************************************
* INCOMPATIBILITY WARNING - L0100-E1/E2 & L0118 *
* ----------------------------------------------- *
* The new L0100-E1/E2 and L0118 "10-TICK-MODE" design changes are *
* *** INCOMPATIBLE *** with current L0100-D1 design, and CI/HSC- *
* LINK modules (L0100-E, CIBCA, L0118) set to "7-TICK-MODE". *
* Mixed "7 and 10-TICK-MODE" CI-LINK operation can have severe *
* impact on CI-arbitration performance and collision-rate (NO_RSP). *
* For this reason, DEC does not support "10-TICK-MODE" CI-LINK *
* ROLLING-UPGRADES, thus requiring a CLUSTER SHUTDOWN to "ENABLE" *
* 10-TICK-MODE ** ONLY ** after all CI/HSC-nodes have been FCO'd. *
* *
* NOTE: High-availability customer exceptions to CLUSTER- *
* SHUTDOWN "rule" should be referred to CSSE for advice on *
* minimizing risks; but DEC will not assume any liabilities *
* for lost data/time with such CLUSTER upgrade programs. *

o Forecast and obtain sufficient CI/HSCxx L0100 FCO kits for all CI7x0,
CIBCI, HSCxx Cluster Nodes, ensuring availability of 1 (one) spare
for every 10 (ten) FCO kits. FCO kits should NOT BE "P1 ORDERED",
but should be ordered according to the Corporate Implementation
Plan. CIxxx Functional Diags (EVGAA/B) from VAX Diag. Rel #31 are
also recommended for checkout.
o Study SWITCH/JUMPER SET-UP Procedures for L0100, L0118, and CIBCA
T1025 modules for adjusting the following CI-LINK functions/modes:
- "7/10-TICK" DELTA-TIME/QUIET-SLOT:
+ L0118 Page 7. Step 10
+ L0100-E Page 7, Step 10
+ T1025/CIBCA Page 7, Step 10 and
CIBCA USER'S GUIDE Pg. 2-12
- CLUSTER-SIZE of 16/32 NODES:
+ L0118 Page 7, Step 10
+ L0100-E NOT APPLICABLE
+ T1025/CIBCA Page 7, Step 10 and
CIBCA USER'S GUIDE Pg. 2-13
- L0118 CI-LINK-MODE JUMPERS: Page 7, Step 10.
o Install L0118 set to "7-TICK/COMPATIBLE-MODE" in all CI780, CI750,
CIBCI, and HSC50/70 Cluster nodes. There are no prerequisite/co-
requisite CIxxx or HSCxx FCOs (modules or microcode) required for
L0118 upgrade in "7-TICK 16-NODE MODE", but CI780.BIN Version V8.0
and CIBCA.BIN Version V5.3 are recommended.
o Schedule & perform cluster shutdown after all non-CIBCA nodes are
upgraded/FCO'd, and have been tested and verified to function in
"7-TICK-MODE" operation under VMS. VMS system-testing is important
to early detection and repair of any DOA FCO modules, prior to
disrupting VAXcluster for CI-LINK 7-to-10-TICK mode-change.
*********************************************************
* IMPORTANT NOTE === IMPORTANT NOTE *
* Customer should be involved or perform all CLUSTER- *
* wide or node-specific VAX and HSC STARTUPS, BOOTS, *
* and SHUTDOWNS. *
*********************************************************
o Switch all L0100-E, L0118, and T1025/CIBCA to "10-TICK-MODE"
"INCOMPATIBLE" operation. Ensure all CIs and HSCs are powered-off
before changing switches/jumpers. Refer to appropriate FCO steps.
Any planned CI-NODE-ADDRESSS changes should also be made at this
time, with consideration of VMS SYSGEN and DECNET parameter changes
required on reboot.
o Reboot cluster, with customer consent, starting with HSCs.

EVGAA 4.1 CI Functional Diag Part I
EVGAB 4.1 CI Functional Diag Part II
WARNING: EVGAA/B may report "false errors" when connected to "live"
CLUSTER due to receipt of SCS START-DATAGRAMS from VMS.
16. Remove the loopback attenuators and reconnect the BNCIA cables
to their original SC008 ports.
17. Boot system into VAXcluster, using customer's "standard operating
procedures". IT IS PREFERRED THAT THE CUSTOMER PERFORM THIS STEP.
EVERY UPGRADED CI/HSC NODE WITH NEW L0100-E*/L0118 SHOULD
BE TESTED UNDER VMS IN "7-TICK ECO-OFF MODE" TO SYSTEM-TEST
NEW FCO PARTS PRIOR TO CLUSTER-WIDE CI-LINK-MODE TRANSITION.
18. UPGRADE remaining CI750, CI780, CIBCI, HSC50, & HSC70 nodes
that do not contain L0100-E1/E2 or L0118 CI-LINK module.
*** REPEAT STEP 1 UNTIL ALL NODES ARE COMPLETED. ***
19. Set all CI/HSC nodes to "10-TICK, INCOMPATIBLE, ECO-ENABLED
MODE" operation. *** THIS REQUIRES ENTIRE CLUSTER-SHUTDOWN
TO AVOID CI-PATH FAILURES, CLUSTER-MEMBER LOSS, AND RISKS TO
DATA-INTEGRITY. *** Ensure each CI is powered off when
changing jumpers.
Set "10-TICK, INCOMPATIBLE, ECO-ENABLED MODE" by referring
