Abstract: A method, computer program product, and system that enable automated creation of operating system handles in response to storage access control changes. A determination is made of the storage array LUNs to which a host has access control permission. Those storage array LUNs and the array port WWN are provided to the host so that the host can efficiently create an OS handle. Each LUN is associated with a target assigned by the host. Configuration information for the host is automatically changed to include the association between the LUN and the target. The host is re-initialized using the configuration information such that an operating system handle is created for the association.
