Patent ID: 8135981

Claim:
A method comprising: obtaining a plurality of parameters associated with each of a first storage resource of a first cluster and a second storage resource of a second cluster, wherein the first cluster is operable to provide computing services to one or more client systems, the computing services comprise an application that is hosted by the first cluster, the application hosted by the first cluster uses data that is stored by the first cluster, the second cluster comprises replicated data that is replicated from the data on the first cluster, the second cluster is operable to provide the computing services to the client system(s) responsive to a failover from the first cluster, the first storage resource of the first cluster stores the data used by the application, and the second storage resource of the second cluster stores the replicated data that is operable to be used by the application when hosted by the second cluster, the plurality of parameters associated with the first and second storage resources comprise first and second logical unit numbers, respectively; detecting, as a function of the plurality of parameters, at least one anomaly of the first cluster or the second cluster wherein the detecting is performed after the data is replicated to the second cluster as the replicated data, the at least one anomaly indicates a mismatch between the first storage resource associated with the first logical unit number and the second storage resource associated with the second logical unit numbers; and generating an alert in response to detecting the at least one anomaly.
