5.3 Adding New OES 2 Linux Cluster Nodes to
Your OES 1 Linux Cluster
The process for adding a new OES 2 Linux cluster node to an existing OES 1 Linux cluster is the
same as for adding an OES 1 cluster node to an OES 1 Linux cluster and adding a new OES 2 cluster
node to an existing OES 2 cluster. See
However, you should be aware of the rules that apply to mixed OES 1 and OES 2 clusters. See
Section 5.1, "Requirements and Guidelines for Upgrading Clusters from OES 1 Linux and OES 2
Linux," on page
55.
5.4 Modifying Cluster Resource Scripts for
Mixed OES 1 Linux and OES 2 Linux Clusters
OES 1 Linux and OES 2 Linux cluster resource load and unload scripts perform similar actions, but
some template scripts differ in the functions used to perform those actions. OES 2 cluster template
scripts have been upgraded and some of them now conform to the Open Cluster Framework (OCF).
Cluster resources created on an OES 1 Linux cluster server can run in a mixed version cluster on
either OES 1 or OES 2 Linux cluster servers.
Cluster resources created on an OES 2 Linux cluster server that is part of an OES 1 and OES 2 Linux
mixed cluster can also run either OES 1 and OES 2 cluster servers.
After completing the cluster upgrade to OES 2 you must finalize the cluster upgrade. See
the Cluster Upgrade
below for more information. Any new cluster resources that are created using
resource templates included with OES 2 Linux use upgraded templates after finalizing the cluster
upgrade. New resources created after finalizing the upgrade cannot run on OES 1 Linux cluster
nodes, so you should finalize the cluster upgrade only after all nodes have been upgraded to OES 2
Linux.
After you have finalized the cluster upgrade you, might want to change the scripts for existing
cluster resources that were created by using templates so that they use the scripts in the upgraded
templates. This is especially true if you want to use the new resource monitoring feature. There are
three ways to do this:
Copy and paste the scripts from the upgraded resource templates to existing resource scripts
and then customize the scripts for the resource.
Offline an existing resource and then create a new resource with a different name to replace the
existing resource, using the upgraded templates.
Offline and then delete an existing resource, then create a new resource with the same name to
replace the existing resource, using the upgraded templates.
5.5 Finalizing the Cluster Upgrade
If you have upgraded all nodes in an OES 1 Linux cluster to OES 2 Linux, you must finalize the
upgrade process by issuing the
