Deactivation occurs when the Analysis Engine tells the running OS to immediately stop using a FRU or part of a FRU. Some components (such as CPU cores) can be deactivated while the OS continues to run, while others can't and must be deconfigured on a reboot. When a service action is performed on a FRU, the Analysis Engine will acquit the FRU automatically if possible. Acquittal means the FRU is considered to have been serviced and is considered ready for service. The acquittal cause and time are logged within the corresponding indictment, which is preserved to provide a history. The user can also acquit FRUs manually, using OA commands. Once the action is initiated, CAE sends a request to Health Repository to update its database for any actions taken on a FRU and also sends a WS-Man alert to notify the customer when an actionable problem is detected. CAE also creates an event indication that can be viewed from the CAE Event Viewer from OA CLI and the Health of the FRU can be viewed from the Health Repository Viewer. Health Repository The Health Repository (HR) provides a single user interface for service personnel to see the health of the whole complex without having to log into each partition.HR stores the FRU data, the installation history and the error history.HR also writes failure data into the FRU so that when the FRU is replaced and taken for repair, the repair depots can do further analysis from the error data written on the FRU. Web Services for Management (WS-MAN) WS-Management, or WS-Manage - refers to the Web Services for Management specification published by the Distributed Management Task Force (DMTF). WS-MAN is a SOAP based protocol which provides a common way for systems to access and exchange management information. For HP Superdome 2, WS-MAN is the primary and the mandatory event reporting protocol for exchanging health management information between management apps in the data center and the Superdome 2 platform. The main component of WS-MAN on HP Superdome 2 is the WS-MAN daemon running on the HP Superdome 2 OA. WS-Man daemon reads requests for data transfer, subscriptions etc and acts on those requests. The WS-MAN daemon supports the Subscribe and Unsubscribe WS-MAN commands. Subscribe indicates to the OA that a client system wants to receive future events. The WS-MAN daemon will save a persistent copy of subscriptions and hence all the subscriptions remain active even after system boot. A client can delete its subscription by sending an Unsubscribe command. 5
