    • Provided are a method, system, and article of manufacture for managing the copying of writes from primary storages to secondary storages across different networks. Information is maintained on a first group of at least one primary storage, at least one primary device managing Input/Output (I/O) access to the at least one primary storage, and at least one corresponding secondary storage to which writes to the at least one primary storage are copied and a second group of at least one primary storage, at least one primary device managing Input/Output (I/O) access to the at least one primary storage, and at least one corresponding secondary storage to which writes to the at least one primary storage are copied. A failure notification is received from one of the primary devices in the first or second group of a failure to copy a write from the primary device to the secondary device. A freeze command is issued over a first network, using a first network protocol, to the at least one primary device in the first group to stop copying writes to the corresponding at least one secondary device. A freeze command is issued over a second network, using a second network protocol, to the at least one primary device in the second group to stop copying writes to the corresponding at least one secondary device.
    • 提供了一种用于管理从主存储器复制到跨不同网络的二级存储器的方法,系统和制品。 信息被维护在至少一个主存储器的第一组上,管理对至少一个主存储器的输入/输出(I / O)访问的至少一个主要设备以及至少一个对应的辅助存储器 至少一个主存储器被复制,并且第二组至少一个主存储器,管理对至少一个主存储器的输入/输出(I / O)访问的至少一个主要设备以及至少一个对应的辅助存储器 至少一个主存储器被复制。 从第一组或第二组中的一个主设备接收到从主设备复制到辅助设备的写入失败的故障通知。 通过使用第一网络协议的第一网络向第一组中的至少一个主设备发出冻结命令,以停止对相应的至少一个辅助设备的写入。 通过使用第二网络协议的第二网络向第二组中的至少一个主设备发出冻结命令,以停止对相应的至少一个辅助设备的写入。

    • A first logical partition in a first processing complex of a server cluster is operated at a first level of a software code. Software code in a second logical partition in the same processing complex is changed to a second level. Processing operations are transferred from the first logical partition in the first processing complex to a third logical partition in a second processing complex of the server cluster. In another aspect, the transferring of processing operations includes quiescing the first logical partition to cause a failover of processing operations from the first logical partition in the first processing complex, to the third logical partition in the second processing complex. In yet another aspect, a failback operation is performed and a first portion of the processing operations are transferred from the third logical partition in the second processing complex, to the second logical partition in the first processing complex. In still another aspect, a second portion of the processing operations may be transferred from the third logical partition in the second processing complex, to the second logical partition in the first processing complex of the server cluster. In one example, the transferring of the second portion of processing operations includes quiescing the third logical partition to cause a failover of processing operations from the third logical partition in the second processing complex, to the second logical partition in the first processing complex. Other embodiments are described and claimed.
    • 服务器集群的第一处理复合体中的第一逻辑分区在软件代码的第一级操作。 相同处理组合中第二个逻辑分区中的软件代码更改为第二个级别。 处理操作从第一处理复合体中的第一逻辑分区传送到服务器集群的第二处理复合体中的第三逻辑分区。 在另一方面,处理操作的传送包括使第一逻辑分区停顿以使处理操作从第一处理复数中的第一逻辑分区到第二处理复合体中的第三逻辑分区的故障转移。 在另一方面,执行故障恢复操作,并且处理操作的第一部分从第二处理复合体中的第三逻辑分区传送到第一处理复合体中的第二逻辑分区。 在另一方面,处理操作的第二部分可以从第二处理复合体中的第三逻辑分区传送到服务器集群的第一处理复合体中的第二逻辑分区。 在一个示例中,第二部分处理操作的传送包括使第三逻辑分区停顿以使处理操作从第二处理复合体中的第三逻辑分区到第一处理复合体中的第二逻辑分区的故障切换。 描述和要求保护其他实施例。
