    • An initial program load (IPL) of a logical partition (LPAR) is managed by establishing a logical path to the LPAR from a storage controller. When a notice is received by the storage controller from the LPAR that the IPL has commenced, the LPAR address is stored in a data structure. After the storage controller initiates a pack change state interrupt, the stored address is compared with the addresses in a list of all LPARS to which the interrupt is directed. If the list of addresses includes the stored address, the stored address is removed from the list. Thus, the pack change state interrupt is transmitted only to the addresses in the list, leaving the LPAR to complete the IPL without interruption. After the storage controller receives a notice from the LPAR that the IPL has completed, the address of the LPAR is removed from the data structure.
    • 通过从存储控制器建立到LPAR的逻辑路径来管理逻辑分区(LPAR)的初始程序加载(IPL)。 当存储控制器从LPAR接收到IPL已经开始的通知时,LPAR地址被存储在数据结构中。 存储控制器启动包更改状态中断后,将存储的地址与中断所针对的所有LPARS列表中的地址进行比较。 如果地址列表包含存储的地址,则从列表中删除存储的地址。 因此,包改变状态中断仅发送到列表中的地址,使LPAR不间断地完成IPL。 在存储控制器从LPAR接收到IPL已经完成的通知之后,从数据结构中删除LPAR的地址。

    • A mechanism is provided in a storage control unit in a data processing system for providing unsolicited global disconnect requests to users. The mechanism stores lock control data in the storage control unit. The storage control unit allocates its resources into a plurality of clusters. Responsive to a given user connecting to a given partition that is for a logical subsystem resident on a first cluster within the plurality of clusters, the mechanism sends reflected partition information from the first cluster to a second cluster within the plurality of clusters. Responsive to the first cluster experiencing a failure condition, the mechanism moves control data from one or more logical subsystems from the first cluster to the second cluster and for each logical subsystem that moved from the first logical subsystem to the second logical subsystem and that has reflected partition information, presents unsolicited status to one or more users.
    • 在数据处理系统中的存储控制单元中提供一种机制,用于向用户提供未经请求的全局断开请求。 该机构将锁定控制数据存储在存储控制单元中。 存储控制单元将其资源分配到多个集群中。 响应于连接到驻留在多个集群中的第一集群上的逻辑子系统的给定分区的给定用户,机制将反映的分区信息从第一集群发送到多个集群内的第二集群。 响应于遇到故障条件的第一个集群,该机制将控制数据从一个或多个逻辑子系统从第一个集群移动到第二个集群,并将每个逻辑子系统从第一个逻辑子系统移动到第二个逻辑子系统, 分区信息,向一个或多个用户显示非请求状态。
