_ DEC-O-LOG for HSC70

_ DOL, HSC70-I001, HSC70 CONTROLLER JUL 88

PROBLEM: Clusters of 6 or more CI/HSC nodes
on SC008 may exhibit CI_PATH NO_RSP or NAK,
ARB-TIMEOUTS, and VC-CLOSURE.  L0118 (and
L0100 Rev. E*) corrects adjacent-node
collision and ARB problems.     

FIELD EFFECTIVITY: The L0118 Rev. B* module
should be installed on all CI750, CI780,
CIBCI, and HSCXX nodes used in VAXclusters
of 6 (Six) or more CI/HSC nodes connected to
a common SC008 Star Coupler.  L0118s should
replace all L0100 Rev. D* link modules; L0118
Rev. E* can coexist with L0118s except in
greater than 16 node environment.     

QUICK CHECK: Check that link module is part
number L0118.

PROBLEM: 1. K.ci init diagnostic does not detect Link Modules that
answer to addresses other than its own. 2. Possible data corruption of
HSC crashes running with RA70 disk drives. 3. Code to support node
numbers over 15 and the CISCE. 4. Support for future products. 5.
Arbitration time-out value set to 2.5 ms instead of 25ms. 6. Servicing
SNDDAT packets could cause RTNDAT/CNF time-outs. 7. Receiving a
message with no credit avilable can cause a host clear.

FIELD EFFECTIVITY: Should be installed on all HSC70 Controllers.  This
FCO incorporates ECOS: L0107-CX0006 and L0107-CX0007. QUICK CHECK:
Type a Control Y on the HSC terminal.  At the HSC prompt, type SHOW
REQUESTOR.  On the line for requestor 1, if the value for "MC" is 54
or higher, this FCO does not need to be installed.

_ DOL, HSC70-I003, HSC70 Storage Controllers, Jun 91

PROBLEM: The CIXCD  option requires an L0118 or an L0100 Min. Rev E.
The L0100 Rev E. cannot be used when the cluster is over 16 nodes
or contains an HSC60/90.

FIELD EFFECTIVITY:  When installing a 9XXX or 65XX system with a CIXCD
or when upgrading an existing cluster with a CIXCD, replace ALL L0100
Rev "D" modules with L0118-** or L0100 Rev "E" modules (if available).
This FCO affects all CI750, CI780, CIBCI and HSC50/70 nodes in
VAXclusters containing a CIXCD.  **NOTE** An L0100 Rev E can coexist
with L0118s except in a greater than 16 node environment or when used
with HSC60/90s.

QUICK CHECK:  Check that link module is part number L0118-** or L0100
Min. Rev E.
