摘要： A method for verifying an input/output (I/O) hardware configuration is provided. A verification command is processed. The verification command includes a software device address range associated with a logical control unit (LCU) of the I/O hardware. The LCU utilizes a first logical path. The software device address range utilizing the first logical path is compared with an existing software device address range utilizing at least one additional logical path. The verification command is accepted if the software device address range and the existing software device address range match.
摘要翻译：提供了用于验证输入/输出（I / O）硬件配置的方法。处理验证命令。验证命令包括与I / O硬件的逻辑控制单元（LCU）相关联的软件设备地址范围。 LCU利用第一逻辑路径。使用第一逻辑路径的软件设备地址范围与利用至少一个附加逻辑路径的现有软件设备地址范围进行比较。如果软件设备地址范围和现有的软件设备地址范围匹配，则接受验证命令。

摘要： A system and method for recovering from a single logical path failure. More specifically, although a host has not grouped its logical paths, the host knows which logical paths it has available. When a host detects a logical path failure, the host enters a path discovery mode of operation. If the host continues to detect a logical path failure while operating in the logical path discovery mode of operation, the host removes the logical path from a logical path mask, and the host does not use the removed logical path again. In the case of ungrouped logical paths, the host aborts its process because it does not have more paths available to continue its process. Additionally, in certain embodiments, a pseudo path group for ungrouped logical paths is created.
摘要翻译：用于从单个逻辑路径故障恢复的系统和方法。更具体地说，尽管主机没有对其逻辑路径进行分组，但主机知道其可用的逻辑路径。当主机检测到逻辑路径故障时，主机将进入路径发现操作模式。如果在逻辑路径发现操作模式下主机继续检测到逻辑路径故障，则主机从逻辑路径掩码中删除逻辑路径，并且主机不再使用已删除的逻辑路径。在未分组的逻辑路径的情况下，主机中止其进程，因为它没有更多可用的路径来继续其进程。另外，在某些实施例中，创建用于未分组的逻辑路径的伪路径组。

If the host continues to detect a logical path failure while operating in the logical path discovery mode of operation, the host removes the logical path from a logical path mask, and the host does not use the removed logical path again. Additionally, the system and method facilitates recovery of the failed logical paths by using a plurality of logical path masks. A first mask is referred to as an intermediate failure logical path mask and a second mask is referred to as a permanent failure logical path mask.
