    • Provided are a method, system, and program for reassigning storage volumes from a failed processing system to a surviving processing system. A first processing system detects a failure of a second processing system. The first processing system determines device groups of storage devices managed by the failed second processing system and determines for each determined device group, hosts that connect to storage devices in the device group. The first processing system sends, for each device group, a unit check to each determined host indicating failure of each device group through one storage device in the device group to which the determined host connects. The determined hosts execute instructions to terminate any I/O operations in progress on the storage devices in the device group in response to the unit check indicating failure of one storage device in the device group and issue, a command to one storage device for the device group to end the busy condition.
    • 提供了一种用于将存储卷从故障处理系统重新分配给幸存处理系统的方法,系统和程序。 第一处理系统检测第二处理系统的故障。 第一处理系统确定由故障的第二处理系统管理的存储设备的设备组,并且为每个确定的设备组确定连接到设备组中的存储设备的主机。 第一处理系统针对每个设备组,通过所确定的主机连接的设备组中的一个存储设备向每个确定的主机发送指示每个设备组的故障的单元检查。 确定的主机响应于单元检查指示设备组中的一个存储设备的故障并发出的命令,执行指令以终止设备组中的存储设备上正在进行的任何I / O操作,命令到设备的一个存储设备 组结束繁忙的状况。
