When the SCSI (Small Computer System Interface) device has been reserved by other application host, and another application host was going to use the device, the message is outputted. The SCSI reservation is usually used for exclusive access to a joint disk between systems which constitute a cluster machine. In case of a disk being reserved in one system, any commands fail entirely from another system to the disk, and the RESERVATION_CONFLICT error occurs.

Because somebody reserves the device, it needs to search the object. In case of tearing away the reservation from other system by all means, the reservation state is cancelde by sending DEVICE_RESET or BUS_DEVICE_RESET to the device.
