Changes to referenced attributes do not propagate

Last published : Oct 01, 2026
This behavior applies to resources referencing attributes of other resources; that is, the ArgList of one resource (A) passes an attribute of another resource (B). If resource B is deleted from the group, or if the SystemList of the group containing resource B does not contain a system defined in the SystemList of the group containing resource A, the VCS engine does not propagate these changes to the agent monitoring resource A. This failure to propagate the changes may cause resource A to fault because it does not receive the appropriate attribute values from resource B.
In such situations, you must reset the value of resource B in the attribute definition of resource A or restart the agent managing resource A.
For example, the ArgList of the MountV resource contains the DiskGroupName attribute of the VMDg resource. If you change the VMDg resource name or the SystemList, the VCS engine does not communicate the change to the MountV agent, causing it to fault. In such a situation, you can reconfigure the MountV agent using one of the following methods:
  • Refresh the VMDgResName attribute for the MountV resource. Set the attribute to an empty string "" first, then reset it to the new VMDg resource name.
  • Stop and restart the MountV agent on the system.
