The tape drive 100 has a data interface 128, such as a FibreChannel (FC) port, for coupling multiple host computers or requesters connected to the tape drive by a network 130. The tape drive can receive an interleaved sequence of commands 146, 148, 144 and 142 from the various host computers for data backup. The history of at least the command types is stored in a command log 120 of the tape drive. The computer ID can also be logged with the command type. This log can be for identification of potentially conflicting commands received from different host computers by using a rule base 126. An analysis application 136 can also be used to analyse the log and display information to a user. |
