Disclosed are a method, a system, a computer program product for fencing a tape drive such that the fence is understood by all hosts that are connected to the tape drive. The tape drive is coupled to a first and a second host. If it is determined that the tape drive needs to be fenced a fence command is sent by a first host. The tape drive receives the fence command and in response fences the tape drive. If a second host sends a command that requires tape movement the tape drive returns a message to the second host informing the second host of a fenced status of the fenced tape drive. Further, the fenced state may be stored in non-volatile memory, thus, the fenced state remains and is persistent when the tape drive is power cycled.
