Mixed-Version Support in an OpenVMS Cluster Environment
Warranted support means that HP has fully qualified the two versions coexisting in an OpenVMS Cluster and will answer all problems identified by customers using these configurations.
Migration support means that HP has qualified the versions for use together in configurations that are migrating in a staged fashion to a newer version of OpenVMS. Problem reports submitted against these configurations will be answered by HP. However, in exceptional cases, HP may request that you move to a warranted configuration as part of the solution. Migration support helps customers move to warranted OpenVMS Cluster pairs. The OpenVMS Version 8.2 release includes no configurations specific to migration support.
Warranted support is provided for the following version groupings:
System disks are architecture specific and can be shared
only by systems of the same architecture. An Alpha and I64 system,
or an Alpha and VAX system, cannot boot from the same system disk.
However, cross-architecture satellite booting is supported. When
you configure an OpenVMS Cluster to take advantage of cross-architecture
booting, make sure that at least one system from each architecture
is configured with a disk that can be used for installations and
upgrades. For more information, refer to the Guidelines for OpenVMS Cluster Configurations and HP OpenVMS Cluster Systems manuals. Only two architectures are supported in the same OpenVMS Cluster. |

In addition, refer to the following Web site for the OpenVMS Operating System Support Chart:

In a mixed-version cluster, you might need to install remedial kits on earlier versions of OpenVMS. For a complete list of required remedial kits, refer to the HP OpenVMS Version 8.2 Release Notes . In a mixed-architecture cluster, you need to install an LMF patch on any OpenVMS Version 7.3-2 Alpha members.
For information about supporting the Performance Data Collector base software (TDC_RT) in OpenVMS Clusters, see Installation in OpenVMS Clusters.
