| 发明名称 | Method to allow a host to replace logical path resources it owns | ||
| 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. | ||

| 主权项 | 1. A method comprising: sending, by a host to a storage controller, a logical path replaceable notification to a logical path resource, the logical path replaceable notification indicating the logical path resource is replaceable by an owner host; determining whether to perform a logical path replacement operation; and performing a logical path replacement operation on the logical path having the logical path replaceable notification, the logical path replacement operation dynamically replacing the logical path resource with another logical path resource. | ||
