ABSTRACT:
In a computer system there is a storage subsystem and an array controller circuit controlling an array of hard drives in the storage subsystem. Upon powering the storage subsystem, the array controller automatically determines whether the hard drives have been moved to new bay locations in the storage subsystem and whether a new complete logical drive, consisting of at least one hard drive, has been added to the storage subsystem. Upon discovery of any drive movement or logical drive unit addition, the array controller automatically reconfigures each hard drive by at least updating the configuration information in accordance with the changes.
