OpenVMS Version 7.3 Release Notes
B.1.8 OpenVMS Cluster Restrictions
Due to controller limitations of the PCMCIA Ethernet card, Compaq
recommends that you use the ALPHAbook 1 computer only as a satellite
node in a cluster environment rather than as a cluster boot node.
The following sections contain release notes pertaining to the
AlphaServer 1000A computer.
You cannot set the console variable BUS_PROBE_ALGORITHM to OLD
on AlphaServer 1000A computers. The default setting is NEW. If
you reset the bus probe algorithm to OLD, your OpenVMS system
will not boot correctly.
When you attempt to install the OpenVMS operating system on an
AlphaServer 1000A computer that uses a DEFPA adapter, the installation
may fail, resulting in a
KERNEL STACK NOT VALID HALT
error message. If this failure occurs, powercycle your system and
restart the installation.
The following sections contain information specific to the AlphaServer
2100 series computer.
On AlphaServer 2100 and 2100A systems, a console display similar to the following is normal and does not represent system errors:
Note that in the previous display, the KZPSA adapter is successfully installed despite the error message displayed in the following lines:
B.3.2 SCSI Controller Restriction
The Adaptec 1740/1742 SCSI controller (PB2HA--SA) is not supported on AlphaServer 2100 systems having more than 1 gigabyte (GB) of memory. If the controller is connected to such a system, the following message appears on the operator's console:
B.4 AlphaServer 4100 (Alpha Only)---EISA Configuration Utility (ECU)
AlphaServer 4100 systems do not support automatic startup of the ECU (EISA Configuration Utility). Instead, follow the procedure described in this section.
If you switch from another operating system to OpenVMS on AlphaServer 4100 systems, you may have to remove EISA boards that have not been qualified on OpenVMS and run the EISA Configuration Utility (ECU).
To run the ECU on other platforms, use the ECU command. To run the ECU on the AlphaServer 4100, use the ALPHABIOS command, and then run the ECU from the ALPHABIOS utility menu.
For more information about using the ECU, refer to the AlphaServer
4100 System Drawer User's Guide.
This section contains release notes pertaining to AlphaServer 8200/8400
The error log buffer size is controlled by the SYSGEN parameter
ERLBUFFERPAGES, which has a maximum value of 32 pagelets. If the Field
Replaceable Unit (FRU) table exceeds this limit during a boot of the
OpenVMS Alpha operating system on an AlphaServer 8200/8400 or 4100
system, an entry will not be written to the error log file.
On AlphaServer 8200 systems, the power regulators do not contain sensors for environmental conditions. Therefore, data cannot be reported in the thermal and power supply MIB groups of the DSM System subagent.
On AlphaServer 8400 systems, the power regulators do contain
environmental sensors, but some configurations may not report
environmental information correctly to the DSM System subagent. This
problem affects the thermal and power supply MIB groups and will be
resolved in a future release of the software.
This section contains a release note pertaining to DEC 7000 systems.
Starting with OpenVMS Alpha Version 7.1, the remote halt command, issued by typing Ctrl/P at the system console, does not work during boot until the copyright banner appears.
In previous versions of OpenVMS, typing Ctrl/P at the system console
always returned the system to the console prompt at any time during the
This section contains release notes pertaining to the DECwindows X11
display server for OpenVMS Alpha systems.
You must install Compaq Open3D (Version 4.9A or later) for OpenVMS Alpha to support the following types of graphics boards on Version 7.3:
B.8.2 S3 Multihead Graphics
Alpha computers equipped with S3 Trio32 or Trio64 graphics cards
support single-screen display only. Multihead graphics are not
Under V7.3, support for graphics boards is fully integrated with the OpenVMS operating system. The following new boards are now supported:
B.9 DIGITAL Modular Computing Components (DMCC) (Alpha Only)
This section contains release notes pertaining to DMCC.
The KZPDA SCSI Controller and the PBXGA Graphics Card cannot be placed
in a slot behind the bridge on the DIGITAL Modular Computing Components
(DMCC) Alpha 5/366 and 5/433 PICMG SBCs.
To update the SRM console on the Alpha 4/233 (21064a), 4/266 (21164a), 5/366, and 5/433 DMCC systems, you must choose either the SRM console or the AlphaBIOS setup. You can store only one console.
If you accidentally update both the SRM and the AlphaBIOS consoles, you will enter the AlphaBIOS Setup menu, and you will not have the option to return to the SRM console. The only way to exit the AlphaBIOS Setup menu and return to the SRM console is to use a Firmware Update Utility located at the following Internet site:
B.10 PowerStorm 300/350 PCI Graphics Controller
This section contains release notes pertaining to the PowerStorm 300
and Powerstorm 350 graphics cards.
For release notes on the Powerstorm 300/350 PCI graphics controller support for a Compaq Workstation running OpenVMS Alpha, refer to the PowerStorm 300/350 OpenVMS Graphics Release Notes Version 1.1. You can find these release notes on the OpenVMS Documentation CD-ROM in the following directory:
These documents, release notes, and installation guides are shipped with the Graphics cards.
Starting with OpenVMS V7.3, the following parameter settings are not
relevant for PowerStorm 300 and 350 graphics cards: MAXBOBMEM,
MAXBOBS0S1, and MAXBOBS2.
On AlphaStation 255 systems using the PowerStorm 3D30 and 4D20 (TGA2)
graphics cards, the system no longer hangs under OpenVMS Version 7.3
when the user selects the InlayColor or InlayPlain backdrop in the
Style Manager's Backdrop dialog box.
Release notes in this section pertain to the RF31T, RF31T+, RF35,
RF35+, RF73, and RF74 DSSI disk devices.
A problem exists with the microcode for earlier versions of RF31T, RF31T+, RF35, RF35+, RF73, and RF74 DSSI disk devices that can cause data loss. The problem can occur when reading data from one of these devices if the device has had a controller memory error (also known as an error detection and correction (EDC) error). The error could have been induced by a virtual circuit closure or faulty hardware.
Compaq advises customers with any of these devices to check their microcode revision levels. If the microcode revision levels are lower than the numbers shown in Table B-1, Compaq recommends that you update the microcode. The microcode for all models, except RF31T, RF31T+, and RF35+, is provided on the latest OpenVMS binary distribution CD-ROM.
The RF_VERS utility, a utility program that displays the microcode revision level of the DSSI disk devices, is also provided on the CD-ROM. Instructions both for using the utility program and for updating the microcode are provided in this section.
The earliest supportable revision levels of the DSSI disk microcode are shown in Table B-1.
To display the microcode revision level of your DSSI disk devices, perform the following steps:
The following is an example of the display produced by the RF_VERS utility:
To update the microcode in your device, use the appropriate command for your device and platform from Table B-2.
