ABSTRACT:
A method and system performs a sendhome procedure for giving back resources to a node that had been restored after a takeover of that node's resources is provided. Critical operations that may be running are completed prior to the sendhome process. An ownership module consults information in an ownership table about each resource, e.g. a data container. A data container, such as a root aggregate of the waiting node is identified and sent back first, after which the node is booted. When the node has been successfully booted, the remaining aggregates are sent back one at a time until the full compliment of aggregates has been returned. A veto of the sendhome procedure can be invoked by a subsystem that is performing a critical operation prior to the sendhome of the root aggregate and each individual other aggregate.
