TITLE: OpenVMS ALPCPU0C04_071 Alpha V7.1 CPU Diagnostics Routines ECO Summary
Modification Date: 25-OCT-1999
Modification Type: Added note regarding Dual CPU Card.
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 the CPU Diagnostics Routines on OpenVMS Alpha V7.1
though V7.1-1H2. This kit addresses the following problems:
Problems Addressed in ALPCPU0C04_071:
o Although improvements to Scatter/Gather code were made, no
customer-visible changes were made. A potential, but so far
unseen problem was fixed. Specifically, an extra read of the
Scatter/Gather maps and a copy of the Scatter/Gather map into
main memory during shutdown was provided. In addition,
changes were made so that any future Scatter/Gather register
crashes could be more easily debugged.
A call to exe_std$alononpaged could cause the system not to
boot if it ran out of nonpaged pool. It was replaced by a
call to exe_std$alophycntg. If this call fails, the boot
proceeds normally, but the Scatter/Gather map is not copied
from I/O space into the dump during a crash.
o Two problems discovered by the new C compiler were fixed,
although neither problem had been reported by customers yet:
1. A RETURN statement was missing the return value
SS$_NORMAL.
2. The variable "ihae" was used when "mhae" was supposed to
have been used.
o When booting a Turbo-Laser, if it crashes before the final exec
initial break point, the user will see a kernel stack not valid
error. The reason for the crash was that the copy_sg_map routine
will access violate if you crash before ioc$init_io_bridge fills
in the virtual address for the scatter gather map.
Problems Addressed in ALPCPUC03_071:
o A hang condition on OpenVMS V7.1-1H1 occurs during initialization
of the I/O database. This hang occurs shortly after the OpenVMS
banner. It can be seen on a verbose boot just after the INITIODB
message. Issuing a CTRL P (^P) to pause the console is ineffective
during the hang.
Problems Addressed in ALPCPUC02_071 ECO:
o CRD errors on the Turbo Laser 4GB memory module (TMEM4) always
contain zero in the failing string register. A hardware
problem in the TMEM4 causes a failure to report the correct
failing string on CRD errors. The inability to determine the
correct failing string prevents DECEVENT from determining the
failing memory SIMM.
o After the installation of a dual CPU card, the cards are not seen
by the operating system or when the DCL 'SHOW CPU/ACTIVE' command
is executed.
NOTE: It is also important to insure that ALL CPU modules are at
similar revisions so that they all have the same version
of the Alpha chip.
Problems Addressed in ALPCPU001_071:
o SMPSTART_MIXEDCPU has been added to the Turbo Laser Link file
so that it will link in the new SMPSTART_MIXEDCPU module which
contains code patches to allow mixing of EV5/EV6 and mixed CPU
passes.
INSTALLATION NOTES:
This kit cannot be booted from a user prompt because it contains a
fix for a problem that prevents OpenVMS from booting. The problem
occurs when devices that use PCI-to-PCI bridged devices are used on
Turbo-Laser systems. To correct this problem, perform the
following steps:
o Remove the devices from the system.
* the PCI-PCI devices for a Turbo-Laser system are:
- ATM350
- KZPDA
o Reboot the system
o Use the the VMSINSTAL utility to install the TIMA kit.
- log into the SYSTEM account and type the following at the
DCL prompt:
@SYS$UPDATE:VMSINSTAL ALPCPUC03_071 [saveset location]
The saveset location may be a tape drive or a disk
directory that contains the kit saveset.
o Shut down the system.
o Re-install the PCI-PCI devices
o Re-boot the system
The images in this kit will not take effect until the system is rebooted.
The fix only applies to TurboLaser systems with PCI-to-PCI bridged
devices installed in them. If you have other TurboLaser nodes with
these devices in your OpenVMS cluster, they must also be rebooted
in order to make use of the new image(s). If the Turbolaser
systems do not use a shared system disk, before each system is
rebooted, the above installation procedure must be performed.
As an alternative to removing the PCI-to-PCI bridged devices, you
can install the TIMA saveset to the destination disk from a working
system. To do this, the destination disk must be a shared disk or
be manually relocated from the destination system to the working
system for installation purposes.
