HP Storage Essentials Enterprise Edition Software - Manual (Page 61)

User Guide 49
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.
