Implementing Resource Type Monitor Code

The cluster administrator can register an upgrade-aware resource type in Sun Cluster 3.0. However, Sun Cluster records the resource type name without the version suffix. To run correctly in Sun Cluster 3.0 and Sun Cluster 3.1, the monitor code for this resource type must be able to handle both naming conventions:

vendor-id.resource-type:rt-version
vendor-id.resource-type

The format of resource type names is described in Format of Resource Type Names.

The cluster administrator cannot register the same version of the resource type twice under two different names. To enable the monitor code to determine the correct name, call these commands in the monitor code:

scha_resourcetype_get -O RT_VERSION -T VEND.myrt
scha_resourcetype_get -O RT_VERSION -T VEND.myrt:vers

Then, compare the output values with vers. Only one of these commands succeeds for a particular value of vers.
