One aspect of the present invention includes performing a quarantine of inaccessible data within a CIM dataset that is managed by a storage service, and a recovery of this data within the CIM dataset once it becomes accessible. In one embodiment, after a first request is made through a CIM agent to the inaccessible data managed by a storage service, the storage service is quarantined within the CIM dataset. This includes terminating any active threads to the service and preventing new threads from accessing the service. Accordingly, the data is hidden from subsequent requests with the CIM agent and any requests to the inaccessible data are prevented. The storage service is then queried so that when the data becomes accessible, the device services for the storage service are restarted. Once restarted, new threads within the CIM agent are able to access the data within the storage service.

CIM data quarantine

One example of this invention defines a new interface to the CIM client API that is more generic than the current standard CIM client API that clients can use for the case where they want to find all relationships between instances of A and B. The method would implement several different ways to retrieve the relationships between A and B. CIM has a concept of a qualifier, which is a tag that can be applied to supply any additional information. The provider could define in the qualifier for each association class which algorithm they think is most efficient, and the implementation of the new interface would use whichever algorithm the qualifier says will be most efficient.
