Yes, this is expected behavior for tape devices, reserve 6/release is sometimes used by backup applications in SAN environments as an arbitration mechanism across multiple machines. Its not that the INQUIRY is failing, its that the st open sequence is doing a reserve/TUR/etc during the open. If that fails then you can't open the drives sufficiently to send a inquiry via pass-through. In some environments you can bypass that processing with O_NDELAY/O_NONBLOCK. Or you just use the sg device which doesn't perform the tape open processing that st does. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
