|Abstract: As part of a total systems design, business continuity procedures must be developed to instruct I/T personnel in the actions that need to be taken in the event of a failure. Testing of those procedures should be performed either during initial installation of the system or at some interval. This paper was written in an effort to assist IBM specialists and customers in developing such testing plans. The paper documents a series of TS7700 Grid failover test scenarios for zOS which were run in an IBM laboratory environment. Single failures of all major components and communication links and some multiple failures are simulated. For each of the scenarios, the MVS console messages that are typically presented are indicated (depending on how the channels are configured between the host and the TS7700, some of the messages may not be generated). Obviously, not all possible failover situations could be covered, the focus of this paper is on those which demonstrate the critical hardware and microcode failover capabilities of the TS7700 Grid configuration.|
