摘要： A storage controller receives an interrupt control directive from a host. The storage controller generates a first plurality of interrupts, in response to access requests received from the host for at least one storage device coupled to the storage controller, wherein the first plurality of interrupts indicates whether access to the at least one storage device is allowed to the host. The storage controller generates a second plurality of interrupts, wherein the second plurality of interrupts comprises unsolicited interrupts for the host that are different from the first plurality of interrupts. The storage controller controls how many of the first plurality of interrupts and how many of the second plurality interrupts to send to the host, based on the received interrupt control directive.

摘要： An apparatus, system, and method are disclosed for an alternate lock facility connection path. A request module receives a connection request to establish redundant connection paths between a control unit and a host. A primary connection module establishes a first connection path between the control unit and the host through a first communication channel. An alternate connection module establishes a second connection path between the control unit and the host through a second communication channel. A detection module detects a failure of the first connection path. A redirection module redirects communication between the control unit and the host through the second connection path upon detection of a failure of the first connection path.

摘要： A method is disclosed to control access to stored information. The method supplies a control unit in communication with a computing device and in communication with stored information. If the computing device requests access to that stored information, the method determines if access to the stored information is available. When access to the stored information becomes available, then the method reserves a communication pathway interconnecting the control unit and the requesting computing device, thereby disallowing the sending of non-MPLF unsolicited status via that reserved communication pathway, and provides a message to the computing device, using that reserved communication pathway, granting access to the stored information.

摘要： A method, apparatus, and computer program product for handling a failure condition in a storage controller is disclosed. In certain embodiments, a method may include initially detecting a failure condition in a storage controller. The failure condition may be associated with a specific host and a specific storage device connected to the storage controller. The method may further include determining a failure ID associated with the failure condition. Using the failure ID, en entry may be located in a data collection and recovery table. This entry may indicate one or more data collection and/or recovery processes to execute in response to the failure condition. The method may then execute the data collection and/or recovery processes indicated in the entry. While executing the data collection and/or recovery processes, connectivity may be maintained between hosts and storage devices not associated with the failure condition.
