You can downgrade a resource to an older version of its resource type. The conditions for downgrading a resource to an older version of the resource type are more restrictive than the conditions for upgrading to a newer version of the resource type. The resource group that contains the resource must be unmanaged.
The instructions that follow explain how to use the clresource command to perform this task. However, you are not restricted to using the clresource command for this task. Instead of the clresource command, you can use Oracle Solaris Cluster Manager or the Resource Group option of the clsetup command to perform this task. See clsetup(8CL) for more information.
clresourcegroup offline resource-group
clresource disable -g resource-group +
clresourcegroup unmanage resource-group
Perform this step only if the version to which you are downgrading is no longer registered. If the version to which you are downgrading is still registered, omit this step.
clresourcetype register resource-type-name
If necessary, edit other properties of the same resource to appropriate values in the same command.
clresource set -p Type_version=old-version resource-todowngrade
# clresource enable -g resource-group +
# clresourcegroup manage resource-group
# clresourcegroup online resource-group
