Abstract
A method and system for automatically sharing a tape drive in a heterogeneous computing environment that includes a first computer and second computer. The first computer receives a message that includes a shared tape drive identifier, a source port identifier of the second computer, and a reservation status change for the tape drive. Based on the tape drive identifier, the first computer determines that the tape drive is connected to the first computer. The source port identifier is determined to not identify any host bus adapter installed in the first computer. In response to the first computer determining that the reservation status change indicates a reservation or a release of the tape drive for the second computer, the first computer sets the tape drive offline or online, respectively, in an application executing in the first computer.
