Bug ID 4369668

Problem Summary: When the system administrator edits the Nodelist property of a managed resource group, the Resource Group Manager should run the INIT method on all resources in the resource group that have the property Init_nodes=RG_PRIMARIES, on all nodes that have been added to the node list. The Resource Group Manager should run the FINI method on such resources, on nodes that were deleted from the node list.Similarly, if the Installed_nodes property of a resource type is edited, the Resource Group Manager should run the INIT or FINI method on all resources of that type that reside in managed resource groups and have the property Init_nodes=RT_installed_nodes.

Currently, the Resource Group Manager does not run INIT or FINI methods when these updates are performed. As a result, the resources might not be properly initialized or cleaned up on these nodes.

Workaround: Using the scswitch command, unmanage and then re-manage the affected resource groups. Unfortunately, this process requires that the administrator take the resource group offline. Alternatively, the administrator can run the equivalent INIT or FINI actions manually (without unmanaging the resource group), if such procedures are documented for the resource types that occur within the group.

This workaround is unnecessary if none of the resources in the group have INIT or FINI methods. The only Sun-supplied resource types that use INIT and FINI methods are:

• SUNW.SharedAddress (shared address resource type)

• SUNW.apache (Apache Web Server) configured in scalable mode

• SUNW.iws (iPlanet/Netscape web server) configured in scalable mode

Resource types that customers or third parties implement might also use INIT or FINI methods. If so, this workaround is necessary for resource groups that contain such resource types.

Note -

All scalable services implicitly use INIT and FINI methods, even if such methods are not explicitly declared for the resource type.
