The retrial queue with unreliable server with provision of temporary server has been studied. A temporary server is installed when the primary server is over loaded. It means that a fixed queue length of K-policy customers including the customer with the primary server has been build up. The primary server may breakdown while rendering service to the customers; it is sent for the repair. This type of queuing system has been investigated using matrix geometric method and obtains the probabilities of the system steady state. From the probabilities, we found some performance measures.
