Because correct configuration data is essential to the operation of any RAID system, and because multiple copies of the configuration data are kept, not only in the RAID controller itself, but also in each disk drive unit in the configuration, it is imperative that the various copies of the configuration data do not become "out of synchronization", which means that one or more copies of the configuration data are different from one or more other copies of the configuration data. To maintain synchronization of all copies of the configuration data, the current invention compares the configuration data stored in the RAID controllers' NVRAM to that of the current system, and records any new, non-responding, repositioned or unidentified storage devices in a change list. The identities and the attachment points of any storage devices in the change list are then displayed to the user, and various options for correcting the lack of synchronization are provided by enabling one or more function keys that may be selected by the user. One such function key, an "accept change" key, causes the configuration data to be modified by changing the current operational state of any non-responding storage device. A "configuration adjustment" key, when selected by the user, causes the configuration data to be modified to reflect any changes in the attachments points of any repositioned storage deices. An "import configuration" key causes the configuration data to be changed to correspond to that of an unidentified storage device. And a "retry" key gives the user an opportunity to rearrange the system and then re-compares the configuration data in the controller to the current system configuration. When the system is operating in un-attended mode, means are disclosed to automatically perform the "accept change", "configuration adjustment" and "import configuration" functions in priority order so long as the "retry" key has not been enabled. The retry key implies attended operation.

An address collision detector is provided such that when both read and write ports in the SRAM block access the same address simultaneously a choice between the data being read can be made between the data presently in the SRAM block or the new data being written to the SRAM block.
