The Question is: Now I want to create cluster with DEC 3000/300 and AlphaStation 200/266,running v6.2. I don't know if the on board scsi can be used ,or I should add another adaptor like KZPSA. The os version now is v6.2. How can I update to 6.2-h3? And what's different between v6.2,v6.2-h1,v6.2h3? The Answer is : Extensive information on configuring Multi-host SCSI is available in the OpenVMS documentation set. Please see this documentation -- there is far more to correctly configuring one of these clusters than can be reasonably included here in Ask The Wizard. You will also want to see the discussion of correctly setting VOTES and EXPECTED_VOTES in the OpenVMS Frequently Asked Questions (FAQ). The KZTSA or similar is required for the DEC 3000 system when multi-host SCSI is required -- the PMAZ controllers are not supported for multi-host SCSI. (For specific hardware support, please see the OpenVMS and OpenVMS Cluster Software Product Descriptions (SPDs) for the desired release(s).) AlphaStation systems can generally be configured into a multi-host SCSI configuration with the integrated SCSI adapter. For multi-host SCSI configurations, you will want to use OpenVMS Alpha V6.2-1H3, or (better) V7.1 or later. V7.1 and later have support for port allocation classes, a feature which can greatly simplify creating multi-host SCSI configurations. OpenVMS V6.2-1H3 is a hardware release that contains all of the V6.2, V6.2-1H1, and V6.2-1H2 releases. V6.2-1H3 contains support for specific new hardware -- such as EV56 (21164A) systems. V6.2-1H3 does not contain ECOs or other changes, if your system is supported by V6.2 and you do not need a configuration or hardware first supported by V6.2-1Hx, there is no need to run V6.2-1H3.
