Patent ID: 8010831

Claim:
A method for recovering computing capacity after a catastrophic failure, said method comprising: monitoring a message traffic between a first computing unit and a second computing unit, said message traffic including one or more predefined error messages, said first and second computing units being remotely located from one another, but functioning essentially as a single computing unit; detecting a loss of a first computing capacity on said first computing unit based on said one or more predefined error messages; determining whether said loss of said first computing capacity is a real loss; and recovering a plurality of specified portions of said first computing capacity on said second computing unit in response to said loss of said first computing capacity being determined a real loss, the plurality of specified portions being determined from a predefined recovery list identifying the plurality of specified portions to be recovered and the order in which the plurality of specified portions are to be recovered; providing a system administrator of said second computing unit an opportunity to override said recovering of said first computing capacity.
