Abstract: Apparatus and methods are provided for recovering from mismatching configuration data in a clustered environment having a plurality of storage devices coupled to a plurality of storage controllers. If a clustered environment has a first storage device of the plurality of storage devices that has first configuration data that does not match second configuration data of a second storage device of the plurality of storage devices, then the mismatch may be resolved through operation of the clustered environment rather than through operator intervention. Comparison of relevant attributes of the first and second configuration data determines whether a relevant difference between the first and second configuration data is a physical status of at least one of the plurality of storage devices.

Abstract: A method and system for validating host bus adapters uses two processing passes. In the first pass, a snapshot of all configuration values of selected peripheral devices is taken. Then, the host bus adapter is powered down for a predefined period of time and powered up again. In the second pass, all the configuration values of the selected peripheral devices are reinitialized in a recursive manner.
