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： A system for providing hosts with a capability to determine which threshold rule of a plurality of threshold rules to use based upon threshold consensus. For example, the system would address a configuration case of several hosts sharing an output port of a fabric via zoning and that port being connected to a single port of a storage controller. If one host is executing lower priority jobs and its threshold is much higher than another host with higher priority jobs and a lower threshold, and the storage controller recognizes that several hosts are sharing the same storage controller port, the consensus will be to ignore the threshold of the first host and to use the threshold of the second host to prevent performance degradation in the system.
摘要翻译：一种用于向主机提供基于阈值共识来确定要使用的多个阈值规则的哪个阈值规则的能力的系统。例如，系统将通过分区和该端口连接到存储控制器的单个端口来解决几个主机共享结构输出端口的配置情况。如果一个主机正在执行较低优先级的作业，并且其阈值远高于具有较高优先级作业和较低阈值的另一个主机，并且存储控制器识别出若干主机正在共享相同的存储控制器端口，则共识将忽略阈值并使用第二个主机的阈值来防止系统中的性能下降。

摘要： A method for replacing logical path resources, a host is able to replace a logical path it owns with a new logical path. Such a system is especially applicable when the condition of “out of resources” has been reached for a port. With this system, a host is guaranteed that it can replace a logical path it owns with a new logical path. It is not necessary for a control unit to have reached its maximum number of logical paths per port. A host is able to replace one logical path with a new logical path any time.
摘要翻译：一种用于替换逻辑路径资源的方法，主机能够用一个新的逻辑路径替换它所拥有的逻辑路径。当港口达到“资源不足”的情况下，这种系统特别适用。使用此系统，可以保证主机可以用新的逻辑路径替换其拥有的逻辑路径。控制单元不必达到每端口最大数量的逻辑路径。主机能够随时用新的逻辑路径替换一个逻辑路径。
