Abstract
The method of the present invention is useful in a computer system including at least two server nodes, each of which execute clustered server software. The program executes a method for providing a transition from a first server node to a second server node. The method includes the steps of responding to a request for the transition and initiating a thread for effecting the transition from the first server node to the second server node. Next, determining if a shared resource is owned by the second server node and if not, calling a driver to enable functionality of the transition, which transition sets up the shared resource access to the second server node.
Claims12
In a computer system including at least two server nodes, each of which execute clustered server software, a method for providing a transition from a first one of said server nodes to a second one of said server nodes, said method comprising the steps of:
- a. in response to a request for said transition, initiating a thread for effecting said transition from said first server node to said second server node;
- b. determining if a shared resource is owned by said second node, and if not;
- c. calling a driver to enable functionality of said transition, which transition sets up said shared resource access to said second server node wherein the method further includes a step of counting the number of resources that have transitioned.
A storage medium encoded with machine-readable computer program code for providing a transition from a first one of said server nodes to a second one of said server nodes, wherein, when the computer program code is executed by a computer, the computer performs the steps of:
- a. in response to a request for said transition, initiating a thread for effecting said transition from said first server node to said second server node;
- b. determining if a shared resource is owned by said second node, and if not;
- c. calling a driver to enable functionality of said transition, which transition sets up said shared resource access to said second server node wherein the computer further performs a step of counting the number of resources that have transitioned.
