Abstract
A computer system and method for caching configuration information for use in mounting and/or unmounting snapshot LUNs of a network-based storage system are disclosed. During a first request to mount a snapshot LUN, a discovery operation is performed at a host system to discover various configuration information used in mounting and unmounting various LUNs of a storage system to a host system. The configuration information is used to process the first request and then the configuration information is cached. During a subsequent request to mount a second snapshot LUN, the cached configuration information can be used to mount the second snapshot LUN, thereby avoiding a second discovery operation.
