Abstract:
1. A computer program product for detecting changes in a storage area network during power off state of a storage array system wherein the storage area network comprises the storage array system, the computer program product comprising a storage medium having computer code, the computer code including instructions comprising: monitoring the storage area network; detecting a triggering event, said triggering event including installation of a component, a removal of a component, and download of firmware update for a component; generating an on power storage profile upon detection of the triggering event; storing the on power storage profile with a time stamp while deleting an old storage profile, wherein the old storage profile has been generated prior to the triggering event; generating an off power profile after a power cycle and after the on power storage profile has been generated; retrieving the on power storage profile; detecting an array configuration change by comparing the off power storage profile and the on power storage profile, the array configuration change including a volume change and a partition change; detecting a plurality of components having changed conditions by comparing the off power storage profile and the on power storage profile; changing a version of the off power storage profile after the comparison of the off power storage profile and the on power storage profile; creating a delta file based on the plurality of detected components; and generating a log entry for each component detected in the delta file.
