Abstract: Disclosed is a computer-implemented method in a storage controller of changing a preferred node from a first node to a second node, comprising: receiving a notification of a request to remove the first node; reporting ports on the first node as non-preferred instead of reporting them as preferred; reporting ports on the second node as preferred instead of reporting them as non-preferred; compiling a target port groups report for each of the first node and the second node; and raising an asymmetric access state changed unit attention notification.

Abstract: A storage area network comprises: one or more replicating source and target storage volumes accessible by one or more hosts; a volume replication status checker for determining an active replication relationship between a source storage volume and a target storage volume; and a volume visibility engine for setting the target storage volume to be hidden from a host if the target storage volume is visible to the host and has a determined active relationship. The volume replication status checker is further for determining an inactive replication relationship between a source storage volume and a target storage volume; and the volume visibility engine is further for setting the target storage volume to be visible to a host if the target storage volume is hidden from the host and has a determined inactive replication relationship.

Abstract: A retractable ball return system having a rebounding surface that is retractable on a roll back into a reel assembly housing, which housing is mountable above a garage door opening or in an open space such as a gymnasium. The rebounding apparatus includes an integrated cable support structure, which is securable at its lower corners to attachment members mounted to the garage door frame. The door frame attachments have a plurality of different connection points which allow the rebounding surface to be secured at different degrees of angle, from angling forward to angling back, or centered in the middle for a perpendicular setting. Once connected, the support cable is retracted, either manually or mechanically, to pull the cable taught, to allow for a strong support structure. The rebounding surface is also then retracted until it has a desired tension level to allow the rebounding surface to be used with different balls as well as to adjust the different performance levels with the same ball.

Abstract: Maintaining operability of a network-connected data processing apparatus is provided. In response to a requirement for failover from a first resource to a second resource, one or more processors tests an availability of the second resource, wherein the first and second resources are redundant resources of a network-connected data processing apparatus that is communicatively coupled to at least one host computer. In response to a positive determination of the availability of the second resource, one or more processors initiates the failover; and in response to a negative determination of the availability of the second resource, one or more processors provides an indication of unavailability.

Abstract: A system, methods, and apparatus for matching employers to employees are disclosed. In an example embodiment, preferences submitted by employers and employees are stored. The preferences may include number of open positions, industry, location, salary, work experience, education level and background information received from employers and employees. The employers may be stably matched to employees in a many to many relationship. The resulting matches may be stable such that (i) no employee would prefer to be unmatched than stay with the employer matched with the employee, (ii) no employer would prefer to be unmatched than stay with the employees matched with the employer, and (iii) no employee and employer that are not matched with each other would prefer to match with each other rather than remain matched with their current matches. The matches may be employer-optimized or employee-optimized.
