    摘要: Provided are a method, system and program for processing complexes to access shared devices. A lock to a plurality of shared devices is maintained and accessible to a first and second processing systems. The first processing complex determines a first delay time and the second processing complex determines a second delay time. The first processing complex issues a request for the lock in response to expiration of the first delay time and the second processing complex issues a request for the lock in response to expiration of the second delay time.

    摘要: Provided are a method, system, and article of manufacture for synchronizing device error information among nodes. A first node performs an action with respect to a first node error counter for a device in communication with the first node and a second node. The first node transmits a message to the second node indicating the device and the action performed with respect to the first node error counter for the device. The second node performs the action indicated in the message with respect to a second node error counter for the device indicated in the message, wherein the second node error counter corresponds to the first node error counter for the device.

    摘要: A method is disclosed to adjust error thresholds in a data storage and retrieval system. The method supplies a data storage and retrieval system comprising memory and microcode, wherein that microcode comprises one or more default error thresholds. The method determines if the memory comprises one or more operational error thresholds. If the method determines that the memory comprises one or more operational error thresholds, then the method operates the data storage and retrieval system using those one or more operational error thresholds. Alternatively, if the method determines that the memory does not comprise one or more operational error thresholds, then the method sets the one or more default error thresholds as the one or more operational error thresholds.

    摘要: An apparatus, system, and method are disclosed for autonomously overriding a global resource lock. The apparatus includes a determination module, an override module, and an assertion module. The determination module determines whether a global resource lock is owned by a peer resource controller and that the peer resource controller is offline in response to the peer resource controller owning the global resource lock. The atomic module atomically overrides ownership of the global resource lock from the peer resource controller. The assertion module asserts active ownership of the global resource lock. The apparatus, system, and method provide an autonomous override of the global resource lock, minimizing system downtime and user intervention.
