HP OpenVMS 8.x manual Warranted Cluster Support, Supported Migration Pairs

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. For the minimum version supported for an upgrade to OpenVMS Version 8.3-1H1, see Section 4.3.1 (page 78).

Warranted cluster support is provided for the combinations shown in Table 2-2. (OpenVMS VAX systems are not supported with OpenVMS I64 systems in the same cluster.)

Table 2-2 Warranted Cluster Support

Operating system	Warranted in these combinations
OpenVMS Alpha Version 8.3	OpenVMS Alpha Version 8.3 and OpenVMS I64 Version 8.3-1H1 or 8.3
	or
	OpenVMS Alpha Version 8.3 and OpenVMS VAX Version 7.3
OpenVMS I64 Version 8.3-1H1	OpenVMS I64 Version 8.3-1H1 or 8.3 and OpenVMS Alpha Version 8.3
	or
	OpenVMS I64 Version 8.3-1H1 and OpenVMS I64 Version 8.3

NOTE: Only two architectures are supported in the same OpenVMS Cluster.

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 between an Alpha and VAX system. 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, see the Guidelines for OpenVMS Cluster Configurations and HP OpenVMS Cluster Systems.

Table 2-3shows the supported migration pairs.

Before introducing an OpenVMS Version 8.3-1H1 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, see the HP
