    Abstract: Provided are a method, system, and article of manufacture for assigning alias addresses to base addresses. An assignment is provided of base addresses to the devices, wherein the base addresses are used to access the devices assigned to the base addresses. An assignment is provided of a plurality of alias addresses to an alias address pool. The alias addresses in the alias address pool are capable of being dynamically assigned to the devices to service I/O requests to the devices. An Input/Output (I/O) request to access one target device comprising one of the devices is processed. A determination is made as to whether the base address assigned to the target device is available. One alias address is assigned to the target device in response to determining that the base address is not available. The I/O request is issued to the assigned alias address to transmit the request to the target device.

    Abstract translation: 提供了一种用于将别名地址分配给基地址的方法，系统和制品。 向设备提供基地址的分配，其中基地址用于访问分配给基地址的设备。 向别名地址池提供多个别名地址的分配。 别名地址池中的别名地址能够被动态分配给设备，以便为设备提供I / O请求。 处理包括其中一个设备的访问一个目标设备的输入/输出（I / O）请求。 确定分配给目标设备的基地址是否可用。 响应于确定基地址不可用，将一个别名地址分配给目标设备。 I / O请求被发送到指定的别名地址，以将请求发送到目标设备。

    Abstract: 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.
