Treatment scheme.
When breaking down for dual control memory device controller below, opposite terminal controller is taken over and is described concrete treatment scheme:
Equipment monitors module monitors to dual control storage device controller fault generation event SMI-S Event, obtains fault object example SMI-S Instance from event, obtains the SMI-S overall identification ObjectPath of failed controller, confirms the source of trouble.
Equipment monitors module according to the SMI-S overall identification ObjectPath of failed controller, calls resource information module from CIM pattern base, obtains the state of failed controller and the type of fault, result is sent to policy enforcement module by service management module.
Policy enforcement module failure judgement type, if controller failure, calls the SMI-S overall identification ObjectPath that resource information module obtains opposite terminal controller from CIM pattern base.
Policy enforcement module is called resource information module and is sent decision-making to corresponding SMI-S Provider and performs request, and the resource take-over module of startup opposite terminal controller is taken over and operated in resource on failed controller or service.
Process terminates.
The realization of Autonomic computing feature.
One, the self-discipline based on strategy manages.
Self-discipline management system will have the functions such as Self-Test Diagnostics, self-configuration, self-regeneration to meet Autonomic computing feature, in design of the present invention, relies on strategy to carry out the realization of these functions.Policy library leaves in self-discipline administration and supervision authorities, and wherein have recorded the information of All Policies, each strategy defines condition and the action of strategy execution, to send event notice when condition is set up, system carries out condition judgment, when condition occurs, and the action executing in notification strategy.Using strategy to make to have nothing to do to the management of memory device and vendor equipment type, is the key of heterogeneous storage network resource management.The implementation of strategy as shown in Figure 3.
Two, based on the tactical management of priority.
If the conditional definition of multiple strategy is identical in self-discipline operating strategy storehouse, then there will be the problem of the action executing according to which strategy definition when this condition occurs.The mode that the present invention is adopted as each strategy definition priority solves this problem, carrys out implementation strategy according to the height of priority; When priority is identical, order strategically performs successively.
Above-mentioned embodiment is only concrete case of the present invention; scope of patent protection of the present invention includes but not limited to above-mentioned embodiment; that any a kind of SMI-S based on Autonomic computing according to the invention stores claims of system for unified management and the those of ordinary skill of any described technical field, to its suitable change done or replacement, all should fall into scope of patent protection of the present invention.
