Abstract
An agent in a storage area network stores a first identifier (e.g., a checksum value) for first zone configuration data previously used to configure a zone in the storage area network. The agent derives the first identifier from contents of the first zone configuration data. Further, the agent retrieves second zone configuration data presently used to configure the zone in the storage area network. The second zone configuration data is potentially different than the first zone configuration data. Based on contents of the second zone configuration data, the agent then produces a second identifier for the second zone configuration data. The agent then compares the first identifier and the second identifier to identify whether the first zone configuration data is different than the second zone configuration data. A user can control behavior of zoning importation and activation depending whether current zone configuration data has been changed.
