HP provides two levels of support for mixed-version and mixed-architecture
OpenVMS Cluster systems: warranted support and migration support.
Warranted support means that HP has
fully qualified the two specified versions coexisting in an OpenVMS Cluster
and will address all problems identified by customers using this
configuration.
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 VAX, OpenVMS Alpha,
or OpenVMS I64. 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 8.2-1 release includes no configurations
specific to migration support.
For the minimum
version supported for an upgrade to OpenVMS I64 Version 8.2-1, refer
to
Upgrade Paths.
Warranted cluster support is provided for OpenVMS I64 Version
8.2-1 in combination with one or more of the following:
OpenVMS I64
Version 8.2
OpenVMS Alpha Version 8.2
OpenVMS Alpha Version 7.3-2
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. (For
this release of OpenVMS I64, satellite booting is not 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
.
Only two architectures are supported in the same OpenVMS Cluster:
OpenVMS I64 and OpenVMS Alpha, or OpenVMS Alpha and OpenVMS VAX,
but not OpenVMS I64 and OpenVMS VAX.

Before introducing an OpenVMS Version 8.2-1 system into an
existing OpenVMS Cluster, you might need to install certain patch
kits (also known as remedial kits) on cluster members running earlier
versions of OpenVMS. For a complete list of required patch kits, refer
to the HP OpenVMS Version 8.2-1 for Integrity Servers

base software (TDC_RT) in OpenVMS Clusters, refer to
