The present invention is directed to a method and system for detecting component level changes in a storage area network during power off state is provided. Storage profile changes may be utilized for monitoring components during a power cycle period of a storage array system coupled to a SAN. During the power on state of the storage array system, a storage profile (an on-power-storage profile) is collected and time stamped after predefined set of trigger points. Another storage profile (an off-power-storage profile) of the same storage array system may be collected immediately after a power cycle. The two versions of the storage profiles are compared immediately after the off-power-storage profile is created to determine whether the predetermined condition happened. A delta file may be generated after the comparison of the two versions of storage profiles. Each detected conditions may be logged in a log file of the storage array system.
