摘要： The invention relates to a disk drive controller system having redundant operations spread between at least two SCSI adaptors connected to a SCSI bus. At least one host computer is also connected to the SCSI bus. If one of the SCSI adaptors fails, the other SCSI adaptor connected to the bus, upon detecting the failure, takes over for the devices serviced by the failing SCSI adaptor. A special termination connection, in which one SCSI adaptor terminates the SCSI bus while the other SCSI adaptor does not, is provided for implementing the invention. A defined process enables the detecting SCSI adaptor to take over for the failed SCSI adaptor and for the failed SCSI adaptor to thereafter return to normal operation.

摘要： The invention relates to a method and apparatus for reordering, at a disk drive controller, a received sequence of read and write commands. The reordering can be system driven so that the system, when a command stalls, examines the command queue for another command to execute. Alternatively, the command queue itself can be reordered depending upon the expected time it takes for various commands to execute. Reordered commands can be flagged so that they cannot be reordered again. The resulting increase in throughput and efficiency occurs without reference to the particular disk drive or disk drive array configuration to which the controller is connected.
摘要翻译：本发明涉及一种用于在盘驱动器控制器处重新排序读取和写入命令的接收序列的方法和装置。重新排序可以是系统驱动的，以便系统在命令停止时检查命令队列以执行另一个命令。或者，命令队列本身可以根据各种命令执行所需的预期时间重新排序。可以对重新排序的命令进行标记，以使其不再重新排序。在不参考与控制器连接的特定磁盘驱动器或磁盘驱动器阵列配置的情况下，产生的吞吐量和效率的增加。

摘要： A method and apparatus, operating in a system having a plurality of host computers and memory system having a disk controller with at least one mass storage device having a plurality of logical volumes, provide for write protecting the logical volumes. The method features writing, in response to a first host, a write protect message to a memory associated with the controller channel directors; polling, from each channel director, the memory for new write protect messages; and preventing, at, for example, the channel director level, a host connected to the channel director from writing to a protected logical volume which is the subject of the write protect message. The write protect status of that channel director, for that logical volume, remains in effect until the write protect condition for that volume has been reset.

摘要： A method of managing a storage system is provided which allows each host of connected to a storage system supporting multiple hosts to view the identification information assigned to the storage devices by the respective hosts. The method includes providing a command which allows a host to write identification information to an area on the disk drives controlled by the host which was previously reserved for use by the storage system. In addition to writing the data to the physical storage device, execution of the command also causes the identification information to be written to an area in global memory which holds information about each of the storage devices in the storage system. Since the information is stored in a global memory, each host my access the information. Using a second command provided, any host may read the information in global memory and thus learn the identification assigned by other hosts. This allows a maintenance utility run on one host to create a cross reference between storage system identifications assigned to the disk drives and host system identifications assigned to the disk drives.
摘要翻译：提供了一种管理存储系统的方法，其允许连接到支持多个主机的存储系统的每个主机查看由相应主机分配给存储设备的识别信息。该方法包括提供一种命令，该命令允许主机将识别信息写入由先前为存储系统使用的主机所控制的磁盘驱动器上的区域。除了将数据写入物理存储装置之外，执行该命令还使识别信息被写入保存有关存储系统中每个存储装置的信息的全局存储器中的区域。由于信息存储在全局内存中，每个主机我都可以访问该信息。使用提供的第二个命令，任何主机都可以读取全局内存中的信息，从而学习其他主机分配的标识。这允许在一个主机上运行的维护实用程序在分配给磁盘驱动器的存储系统标识和分配给磁盘驱动器的主机系统标识之间创建交叉引用。

摘要： A method and apparatus, for a system having a plurality of host computers and a memory system having a disk controller with at least one mass storage device having a plurality of logical volumes, provide for write protecting the logical volumes at the controller port level. The method features changing the write protect status of one or more logical volumes, on a port level basis, in response to a first host request to change a write protect status; writing a write protect status message to a memory associated with the controller channel directors; polling, from each channel director, the memory for an unread write protect status messages; and preventing, at, for example, the channel director port level, a host connected to the channel director from writing to a protected logical volume which is write protected from that host or host port. The write protect status of that channel director, for that logical volume, remains in effect until the write protect condition for that volume has been reset. A lock mechanism must be obtained to make any changes in the logical volume write protect status.

摘要： A data management technique for managing accesses to data at a shared storage system includes a filter at the storage system. The filter is coupled to a configuration table, which identifies which of a number of coupled host processors have accesses to each of the resources at the device. During operation, requests received from the host devices are filtered by the filter, and only those requests to resources that the individual host devices have privilege to access are serviced. Advantageously, data security is further enhanced by authenticating each of the requests received by the storage system to verify that the host processor that is represented as forwarding the request is the indicated host processor. In addition, transfers of data between the storage system and the host processor may be validated to ensure that data was not corrupted during the data transfer.

摘要： A method and data storage system using the method, provides an efficiently approach for allocating a static amount of buffer space (e.g., records) among a number of logical volumes of a data storage system on the basis of the computing environment within which the data storage system is used. The method includes providing the data storage system from logical volumes, each including a command queue. Each command queue includes records, each for storing a command request. A memory pool is established from which one or more records can be allocated to each command queue associated with each logical volume. The memory pool has a predetermined number of records which can be allocated by the command queues of the logical volumes. Based on the computing environment, one of a number of allocation schemes for allocating records to a command queue is selected.
