OpenVMS Version 7.2 Release Notes

This section contains release notes pertaining to AlphaServer 8200/8400 systems.

1.9.1 Problems and Restrictions

The following notes describe restrictions that apply to AlphaServer 8200/8400 systems.

1.9.1.1 Field Replaceable Units (FRU) Table Error

V7.2

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.

1.9.1.2 Environmental Data Restrictions

V7.1--1H1

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 might 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.

1.10 AlphaStation 255 (Alpha Only)

See Section 1.12.2.2 for a release note about using PowerStorm graphics cards on an AlphaStation 255.

The following notes describe restrictions for DMCC.

1.13.1.1 CPUSPINWAIT Crash and Recovery on DMCC 21164A Systems

V7.2

DIGITAL Modular Computing Components 21164A systems may experience the following crash running OpenVMS Version 7.2:

CPUSPINWAIT, CPU spinwait timer expired

To avoid this problem, reboot the system with the SYSTEM_CHECK parameter disabled. Use the following commands when you reboot to disable the SYSTEM_CHECK parameter:

>>> boot -flags, 0,1 bootdevice SYSBOOT> SET SYSTEM_CHECK 0 SYSBOOT> CONTINUE

1.13.1.2 Alpha 5/366 and 5/433 PICMG SBC Restriction

V7.2

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.

1.13.1.3 Updating the SRM Console

V7.2

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 are running OpenVMS on these systems, update only the SRM console.
• If you are running Windows NT on these systems, update only the AlphaBIOS setup.

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 then exit the AlphaBIOS Setup menu and return to the SRM console is to use a Firmware Update Utility located at the following Internet site:

This section contains a release note for the Ohio State University (OSU) HTTP server.

Release notes in this section pertain to the RF31T, RF31T+, RF35, RF35+, RF73, and RF74 DSSI disk devices.

1.15.1 Problems and Restrictions

This section describes a problem found in certain RF31T, RF31T+, RF35, RF35+, RF73, and RF74 DSSI disk devices.

1.15.1.1 RF73 and Other RFnn DSSI Disk Devices and Controller Memory Errors

V6.2

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 1-2, 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 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 1-2.

Table 1-2 Supported Microcode Revision Levels

Device Type	Minimum Level with Supported Microcode
RF31T	T387E
RF31T+	T387E
RF35	T392D
RF35+	T392D
RF36	V427P
RF73	T392D
RF74	V427P

To display the microcode version level of your DSSI disk devices, perform the following steps:

1. Log in to the SYSTEM account or another account that has the CMKRNL, DIAGNOSE, and SYSPRV privileges.
2. Enter the following commands:

   $ SET PROCESS /PRIVILEGE=(DIAGNOSE,CMKRNL,SYSPRV) $ SHOW DEVICE FYA0:

   
   On VAX systems, if the SHOW DEVICE command produces an error, enter the following commands:

   $ RUN SYS$SYSTEM:SYSGEN SYSGEN> CONN FYA0/NOADAP SYSGEN> ^Z

   
   On Alpha systems, if the SHOW DEVICE command produces an error, enter the following commands:

   $ RUN SYS$SYSTEM:SYSMAN SYSMAN> IO CONNECT FYA0: /NOADAP SYSGEN> ^Z

The following is an example of the display produced by the RF_VERS utility:

Program Name: RF_VERS Revision Level: V1.2s NOTICE: This program does not currently support the RF72 or any HSDxx controllers. See next version for support.
