Abstract: An instruction directed towards a network adapter is detected. Based on the detected instruction it is determined that the network adapter should operate in a loopback mode. One or more network signals are transmitted through a dedicated loopback pathway. The transmission is based on the determination. The transmission occurs on a first network interface of the network adapter. The dedicated loopback pathway connects to a second network interface of the network adapter. Listening on the dedicated loopback pathway for the one or more network signals. Performing a network loopback test of the network adapter based on the listening.

Abstract: A request to perform a testing procedure on a multi-client adapter is received. The multi-client adapter is capable of hosting network connectivity for multiple clients simultaneously and operating within a computing system. A client adapter configuration for the multi-client adapter is determined. The client adapter configuration lists clients that are assigned to the multi-client adapter. The computer system is instructed to operate in an I/O error state. The computer system is instructed in response to the received request and based on the determined client adapter configuration. The I/O error state has a time frame for recovery of a first client of the clients assigned to the multi-client adapter. A first adapter test of the testing procedure is performed on the multi-client adapter during the time frame for recovery and based on the received request.
