74 Adding TL895 Tape Drives to the Compaq Enterprise Backup Solution Display of a FC-AL with a Missing Fibre Channel Tape Controller The figure below shows a Fibre Channel Host Controller highlighted with a Fibre Channel Tape Controller missing. This indicates that while the Tape Controller has become inactive on the FC-AL since the utility was started. This could mean that it has been physically disconnected or that errors are occurring on the FC-AL at a great enough frequency to prevent the device from maintaining login. If there are a large number of errors occurring in the FC-AL, the Fibre Channel Host Controller may not be able to communicate with the Fibre Channel Tape Controllers on the FC-AL. In this case, the Fibre Channel Controllers may appear to be offline in the program, although in reality they are physically connected to the FC-AL. When a FC-AL shows errors, the Fibre Channel Array and Tape Controllers may alternate between being logged-on the FC-AL or missing. Figure 6-17.
