The Topology Services component of RSCT directly uses required software components that may manifest problems as error symptoms in the Topology Services component.

If you perform all the diagnostic routines and error responses listed in this section and still have problems with the Topology Services component of RSCT, you should consider these components as possible sources of the error. The following list presents components in the order that they are most likely to introduce an error, from the most likely to the least likely.
  • UDP/IP communication
  • Cluster adapter configuration
  • UNIX Domain sockets
  • Security libraries
  • System Resource Controller (SRC)
  • First Failure Data Capture (FFDC) library
  • /var/ct/cluster_name directory (for RPD)
  • /var/ha directory (for PowerHA® SystemMirror® and PSSP)
