Methods and apparatus for performing data validation in a network management application

A report generator of a storage area network management application includes a data validation mechanism that validates data related to managed resources operating in a storage area network. The data validation mechanism obtains first and second data sets concerning first and second characteristics of a resource operating in the storage area network and applies at least one data validation test using data sets to detect inconsistencies in data in the first and second data sets associated with the resource operating in the storage area network. Values can be compared in different columns of the same or different reports to detect report integrity errors or data mining errors. The report generator provides a storage area network management report based on data of the first data set and the second data set that accounts for inconsistencies in data associated with the resource as detected by the at least one data validation test.
