摘要： An apparatus, clustered computer system, program product and method utilize a unique prepare operation in connection with a resource action to effectively “lock out” missing or inactive cluster entities such as nodes and cluster objects from rejoining a clustered computer system subsequent to the resource action. The prepare operation includes the modification of one or more cluster configuration parameters associated with a plurality of entities in a clustered computer system, such that any such cluster entity that is active during the prepare operation accepts the modifications, while any such cluster entity that is inactive during the prepare operation does not accept the modifications. By modifying cluster configuration parameters for active cluster entities, attempts by previously-inactive cluster entities to activate or rejoin clustering subsequent to resource actions will generally fail due to an incorrect or stale cluster configuration parameters for such entities, and as a result, such entities will be effectively blocked from being accepted into the clustered computer system.
摘要翻译：一种装置，集群计算机系统，程序产品和方法利用与资源动作结合的唯一准备操作，以在资源动作之后有效地“锁定”丢失或不活动的集群实体（例如节点和集群对象）来重新连接集群计算机系统。准备操作包括修改与集群计算机系统中的多个实体相关联的一个或多个集群配置参数，使得在准备操作期间活动的任何这样的集群实体接受修改，而任何此类集群实体处于非活动状态在准备操作期间不接受修改。通过修改活动集群实体的集群配置参数，先前不活动的集群实体在资源操作之后激活或重新加入集群的尝试通常会由于这些实体的不正确或过期的集群配置参数而失败，因此，这些实体将被有效地阻止被接收到集群计算机系统中。

摘要： A computing node that functions as a member within a computing system group, such as a cluster, that has a status allowing receipt of group messages even though the node is not an active member of the cluster. The node is able to function as a primary member or as a backup member that controls redundant resources to be utilized in case of a failure. The computing node is able to have one of two status values, an “Active” status and an “Ineligible” status. Members that are able to function as a primary member have an “Active” status assigned, and a member that is not configured or otherwise eligible to perform as a primary member is assigned an “Ineligible” status. Members with an Ineligible status receive all group messages and therefore are able to become configured and eligible to become a primary member.

摘要： A computing system group processing architecture that facilitates asymmetric processing at different computing nodes within a group or cluster of nodes. Nodes within a group are assigned to subgroups. Each node in a subgroup performs similar processing, but nodes in different subgroups are able to perform different processing for the same group level protocol. All nodes monitor processing completion votes that are cast by all nodes, and node in subgroups that finish processing before other subgroups synchronize to the processing of those other subgroups by casting dummy votes during vote rounds of other subgroups that are still processing their subgroup protocol.

摘要： A method for recovering a computer system from a loadsource direct access storage device located at a remote location. In accordance with the method and system of the present invention, after a catastrophic damage and the installation of a local loadsource direct access storage device, an indicator within the local loadsource direct access storage device is set such that the local loadsource direct access storage device cannot be utilized for initial program load. Thereafter, the contents of the entire loadsource direct access storage device located at a remote location are copied to the replacement local loadsource direct access storage device. The indicator within the replacement local loadsource direct access storage device is reset such that the replacement local loadsource direct access storage device can be utilized for initial program load again. Finally, an initial program load is performed from the replacement local loadsource direct access storage device.

摘要： DASD failures occurring on sector boundaries currently go undetected. While this sort of problem can occur at any time, it usually occurs when the program executing on the computer system's processor is operating on a multisector piece of data and periodically updating that information in auxiliary storage so that the copy in auxiliary storage is relatively up to date with the changes being made by the program. The storage management mechanism of the present invention solves the problem of sector boundary write failures by associating a sequence number with each piece of multisector data. Essentially, the sequence number becomes a property of the particular piece of data itself. When the mechanism retrieves the information from disk, it checks to make sure that all the sequence numbers match. If they do not, a data integrity problem has been detected.
摘要翻译：目前，行业边界上发生的DASD故障尚未被发现。虽然这种问题可能在任何时候发生，但通常在计算机系统处理器上执行的程序在多段数据上运行并且在辅助存储器中定期更新该信息时，会发生辅助存储器中的副本相对较高日期与程序所做的更改。本发明的存储管理机制通过将序列号与每个多维度数据相关联来解决扇区边界写入失败的问题。本质上，序列号成为特定数据本身的属性。当机制从磁盘检索信息时，它检查以确保所有序列号匹配。如果没有，则检测到数据完整性问题。

摘要： A computing system group member, signal bearing medium, and method. A configuration of a computing system group member is determined to be able to assume a role of a primary member of the computing system group and, in response thereto, a first status is assigned in the member. All members of the computing system group receive, in order, all messages directed to group members. A second status is assigned in response to determining that the configuration of the member is not able to support performance as a primary member. The member then processes, within the member, all messages that are transmitted to all members of the group when the member is assigned the first status and when the member is assigned the second status. The configuration of the member, while assigned either the first status or the second status, is adjusted based upon contents of the messages.

摘要： Failover processing that accommodates failures of backup computing nodes and resources, such as data storage units and printers. Failure of a computing node that controls resources causes another computing node to assume control of the resources controlled by the failed node. Failure of the primary computing node causes another computing node, at either the same or at a different site, to be selected as the new primary node. Failure of a resource at the primary site causes the site with the next highest priority backup resource to become the new primary site. Failure of a backup computing node causes a new backup node at the same site as the failed backup node to replace the failed backup node as host for the site's resources. Backup mirroring data flows are then adjusted to reflect the new functions of the affected nodes.
