1. A computer-implemented method comprising: receiving, on an active storage processor from a passive storage processor, a join request indicator, wherein: the join request indicator indicates that the passive storage processor wants to transition to an active status, and the active storage processor and the passive storage processor are both coupled to a data array; providing, from the active storage processor to the passive storage processor, a status change indicator, wherein the status change indicator indicates that the passive-to-active transition of the passive storage processor has been initiated; receiving, on the active storage processor from the passive storage processor, a first data array status indicator, wherein the first data array status indicator indicates the status of the data array as seen by the passive storage processor, wherein the active storage processor receives the first data array status indicator by receiving a mirrored copy of the first data array status indicator generated by the passive storage processor after being locally stored at the passive storage processor; generating, on the active storage processor, a second data array status indicator, wherein the second data array status indicator indicates the status of the data array as seen by the active storage processor; comparing the first data array status indicator to the second data array status indicator to determine if the active storage processor and the passive storage processor are seeing the same status for the data array; and when the active storage processor and the passive storage processor are not seeing the same status for the data array, normalizing the status of the data array so that the active storage processor and the passive storage processor see the same status for the data array, wherein normalizing the status of the data array is accomplished by either normalizing the data array status of the active storage processor to the data array status of the passive storage processor or normalizing the data array status of the passive storage processor to the data array status of the active storage processor; when normalizing the data array status of the active storage processor to the data array status of the passive storage processor, preventing the active storage processor from seeing one or more drives included within the data array; when normalizing the data array status of the passive storage processor to the data array status of the active storage processor, preventing the passive storage processor from seeing one or more drives included within the data array.
