Abstract:
A method, computer program product, and computing system for receiving, on an active storage processor from a passive storage processor, a join request indicator. The join request indicator indicates that the passive storage processor wants to transition to an active status. The active storage processor and the passive storage processor are both coupled to a data array. A status change indicator is provided from the active storage processor to the passive storage processor, wherein the status change indicator indicates that the passive-to-active transition of the passive storage processor has been initiated. A first data array status indicator is received on the active storage processor from the passive storage processor, wherein the first data array status indicator indicates the status of the data array as seen by the passive storage processor. A second data array status indicator is generated on the active storage processor, wherein the second data array status indicator indicates the status of the data array as seen by the active storage processor.
