The Question is: Dear Wizard: I am currently trying to put together some in depth documentation on our Alpha 4000/OpenVMS 7.1-1H1. Has Digital/Compaq prepared a system analysis documentation template that can be used to document all system settings. Any advise you can give would be appreciated. The Answer is : The documentation of all settings is interesting, but a recent valid BACKUP/IMAGE of the disk(s) is usually far more practical, particularly when rapid recovery is required. If the purpose of this documentation is a product installation, the list of logical names, files, and system parameters for inclusion into SYS$SYSTEM:MODPARAMS.DAT is usually more appropriate. If the task is strictly configuration documentation, tools such as CLUE CONFIG, CLUE SCSI/SUMMARY, and (on V7.2 and later) SHOW PARAMETER/ALL can be used to gather system configuration information. These commands are part of the ANALYZE/SYSTEM (SDA) CLUE subsystem available on recent OpenVMS Alpha versions. In addition to SHOW PARAMETER/ALL in SDA, you can also acquire the current parameter settings using the SYSMAN PARAMETER SHOW/ALL command. PRODUCT SHOW PRODUCT can show the currently installed packages, with better ECO coverage particularly on OpenVMS Alpha V7.1-2 and later. Files such as SYS$SYSTEM:AGEN$PARAMS.REPORT can be used to determine settings created by the last AUTOGEN pass. The contents of SYS$SYSTEM:MODPARAMS.DAT should be included in this documentation, as should the output from SHOW LOGICAL/FULL, a copy of all site-specific configuration files, and any other site-specific customizations that might be around. As should become obvious, full documentation of the system configuration is difficult, and recovery from documentation would be tedious at best. (Assuming that all necessary configuration information is archived.) BACKUP/IMAGE makes for a far faster recovery, and is far less prone to various errors and omissions.
