The Application Integration Software for SAP ACC has one very important change in operation

when handling a prepare (attach) operation.

When receiving a prepare request, the Application Integration Software must first determine if the

physical storage associated with this request is already presented to any Managed Node. If the

storage is already presented to a Managed Node and the Managed Node is not accessible, the

physical storage must first be un-presented from that Managed Node before it can be presented to

the requesting node.

This condition is true if the system that was running the application crashed for some reason and is

now not available. The administrator may want to re-start the application on another node. In this

case, the Application Integration Software must ensure that when the crashed server is operational

again, it will not have access to the physical storage.

In the event that the original owner of the physical storage is available, the Application Integration

Software cannot forcefully un-present the storage from this system, since it has no guarantee that the

application is down. In this case, the Application Integration Software must return a failure status for

the prepare operation.
