This section provides requirements and software-support guidelines for all clusters that have a partnership with the global cluster or Oracle Solaris brand zone cluster that you are updating.
Observe the following requirements if you are updating your cluster to the Disaster Recovery framework 4.4 version.
Supported hardware – The cluster hardware must be a supported configuration for Disaster Recovery framework 4.4 software. See the Oracle Solaris Cluster 4 Compatibility Guide for the Disaster Recovery framework configurations that are currently supported.
Minimum Oracle Solaris OS version – Oracle Solaris 11.4 software is the minimum required to support Oracle Solaris Cluster 4.4..
Minimum Oracle Solaris Cluster version – The cluster must run on or be updated to Oracle Solaris Cluster 4.3 software, before updating to Oracle Solaris Cluster 4.4 software. Updating the core Oracle Solaris Cluster software also updates the Disaster Recovery framework software.
Supported Disaster Recovery framework versions in cluster partnerships – All clusters that are in a partnership with the cluster that you are updating to Disaster Recovery framework 4.4 software must run either version 4.3 or 4.4 of the Disaster Recovery framework software. If any node on the partner cluster does not already run one of these versions of Disaster Recovery framework software, you must also update that node to a supported version before you restart the Disaster Recovery framework infrastructure on the updated cluster.
Observe the following requirements if you are installing a software update of your Disaster Recovery framework 4.4 configuration.
You must run the same software updates for Oracle Solaris Cluster software and the common agent container software on all nodes of the same cluster.
Within a cluster, the software updates for each node on which you have installed Disaster Recovery framework software must meet the Oracle Solaris Cluster software update requirements.
All nodes in the same cluster must have the same version of Disaster Recovery framework software and the same software updates. However, primary and secondary clusters can run different versions of Disaster Recovery framework software, provided that each version of the Disaster Recovery framework software is correctly updated and the versions are no more than one release different.
To ensure that the updates have been installed properly, install the software updates on your secondary cluster before you install the software updates on the primary cluster.
