TITLE: OpenVMS VAXPHV01_071 VAX V7.1 FDDI Drivers ECO Summary
Modification Date: 22-FEB-99
Modification Type: New Kit
NOTE: An OpenVMS saveset or PCSI installation file is stored
on the Internet in a self-expanding compressed file.
The name of the compressed file will be kit_name-dcx_vaxexe
for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
Once the file is copied to your system, it can be expanded
by typing RUN compressed_file. The resultant file will
be the OpenVMS saveset or PCSI installation file which
can be used to install the ECO.

ECO KIT SUMMARY:
An ECO kit exists for FDDI Drivers on OpenVMS VAX V7.1. This kit
addresses the following problems:
o For the command:
NCL> SHOW FDDI STATION FDDI-0 * ALL
the SMTstationID field was displayed as '0000000000000000'H,
but should have been '080008002B209E45'H.
o A crash occurred in module FX$SCHED_CMDUNS_FORK while doing a
DEVICELOCK.
The crash occurred under the following conditions:
1. FDDI (DEMFA)
2. MOPRC (60-02)
3. crash address FXDRIVER+022E4
4. current process was running TSM$MAIN
o During testing of failover to a second FDDI controller, after
an FDDI cable was removed, a SET HOST command hung for one
minute, resulting in a bugcheck at TIMER.BUG. Note that the
problem did not cause a fatal error and allowed the FDDI ring
to resynchronize.
o DECnet hung for 1 minute when the FDDI cable was removed from
the bulkhead.
o Attempting to start the MOPRC protocol on a DEMFA returned an
SS$_DEVREQERR error status.
o If a DEMFA FDDI controller fails, then transmit requests can
possibly fail to complete within a timeout period.
The failure that a user sees is that the FDDI path fails and
then the cluster software does not switch to another path,
usually resulting in a CLUEXIT error.
o When the cable is disconnected from the DEMFA FDDI controller,
timing problems can occur in the driver, which could result in
a crash after an extended period of cable disconnections
(typically weeks).
o The LAN Driver received a loopback packet with a broadcast
destination address, which was an invalid use of the loopback
protocol (90-00) format. However, the packet was not regarded
as invalid, resulting in a crash at EZDRIVER+072E3.
o Transmit timeouts errors must be set as fatal.
A problem with failover occurred on the DEMFA on a VAX system.
Although a transmit timeout had occurred, the transmit completed
with an error status and continued. Since the failure happened
in such a way that the link did not go down and come back up, a
failover never happened.
o A crash occurred during timeout processing and it can happen
on a VAX 4000-90, VAX 4000-300, etc., that also has an SGEC
Ethernet adapter.
INSTALLATION NOTES:
The images in this kit will not take effect until the system is
rebooted. If there are other nodes in the VMScluster, they must
also be rebooted in order to make use of the new image(s).
If it is not possible or convenient to reboot the entire cluster at
this time, a rolling re-boot may be performed.
