摘要： Embodiments of the present invention provide a loop network system and data storage devices connected thereto where the data storage devices (nodes) can perform effective pieces of processing and the probability of error occurrence can be reduced. One embodiment according to the present invention includes a Fibre Channel Arbitrated Loop network, a Host controller and multiple HDDs connected thereto. A port on the network outputs parameters to control loop initialization processing as well as a LIP Order Set. Each port performs loop initialization processing according to the received parameters and transfers the received LIP Order Set with parameters appended to the down stream.

摘要： Embodiments in accordance with the present invention relate to determination of a connecting status of a device in a system constituted by a plurality of devices connected via information transmission path in a loop, such as fibre channel arbitrated loop. Particular embodiments of the present invention may help to prevent a bypassed device from performing an improper process at a loop initialization process. According to one embodiment, each device checks its own bypass status at a loop initialization process. The device which has become a loop master determines that it is not bypassed by itself. In an address obtaining step, the device checks whether or not the device itself can actually obtain the address which the device tried to obtain by means of a bit map of the received frame and determines that the device is not bypassed if the address is not obtained. The device checks whether or not the address which has been stored in a predetermined position of a position map exists. If it does not exist, the device determines that it is bypassed.
摘要翻译：根据本发明的实施例涉及确定由通过诸如光纤信道仲裁环路之类的循环中的信息传输路径连接的多个设备构成的系统中的设备的连接状态。本发明的特定实施例可以有助于防止旁路设备在循环初始化过程中执行不正确的过程。根据一个实施例，每个设备在循环初始化过程中检查其自身的旁路状态。已经成为环路主设备的设备确定它不被其自身旁路。在地址获取步骤中，设备检查设备本身是否可以通过接收到的帧的位映射实际获得设备尝试获取的地址，并且如果未获得地址则确定该设备不被旁路。该装置检查存储在位置图的预定位置中的地址是否存在。如果它不存在，则设备确定它被绕过。

摘要： Embodiments of the invention improve the security of data written on a magnetic disk by performing re-allocation processing starting from a sector whose defect is large in automatic re-allocation processing. According to one embodiment of the present invention, after the reliability of each of data sectors that have been read out from a magnetic disk according to a read command is determined, re-allocation processing on the data sectors is performed in the order of increasing reliability. As a result, within a limited period of time, it is possible to replace by priority a data sector where there is a high possibility that data recovery will be unable to be achieved. This makes it possible to increase the security of data and the reliability of the HDD. The reliability of each data sector is determined on the basis of the number of bytes corrected by ECC.
摘要翻译：本发明的实施例通过在自动重新分配处理中从缺陷较大的扇区开始执行重新分配处理来提高写入磁盘的数据的安全性。根据本发明的一个实施例，在确定了根据读取命令从磁盘读出的每个数据扇区的可靠性之后，以可靠性增加的顺序对数据扇区进行重新分配处理。结果，在有限的时间内，可以优先地替换数据扇区，其中存在无法实现数据恢复的可能性高的数据扇区。这使得可以增加数据的安全性和HDD的可靠性。每个数据扇区的可靠性是根据由ECC校正的字节数确定的。
