Abstract: A computer system includes a method for performing background disk sector analysis for drives, including drives dedicated to redundancy and/or fault recovery techniques, in an intelligent, microprocessor based disk array (116). The method directs a microprocessor (20) to wait a specified time and test for disk activity. In the absence of disk activity, the disk controller (112) is directed to generate a read request for a disk memory location within the array. A return code following the array is checked to determine if the read failed, indicating a disk drive media failure. The disk controller (112) is then notified if a failure occurs. The processor again checks for disk array activity and in the absence of activity issues a read request for successive locations within the array, thereby reading all disk memory locations within the array (116).

Abstract: A host computer including a posted write cache for a disk drive system where the posted write cache includes battery backup to protect against potential loss of data in case of a power failure, and also including means for performing a method for determining if live data is present in the posted write cache upon power-up. The posted write cache is further mirrored and parity-checked to assure data validity. Performance increase is achieved since during normal operation data is written to the much faster cache and a completion indication is returned, and the data is flushed to the slower disk drive system at a more opportune time. Batteries provide power to the posted write cache in the event of a power failure. Upon subsequent power-up, a cache signature previously written in the posted write cache indicates that live data still resides in the posted write cache. If the cache signature is not present and the batteries are not fully discharged, a normal power up condition exists. If the cache signature is not present and the batteries are fully discharged, then the user is warned of possible data loss. A configuration identification code assures a proper correspondence between the posted write cache board and the disk drive system. A mirror test executed to verify data validity. Temporary and permanent error conditions are monitored so that posted write operations are only enabled when error-free operation is assured.

Abstract: For use with a computer system having an intelligent mass storage disk array subsystem, including a microprocessor controller, a method for the distribution of data within the disk array based upon logical commands issued by the computer system. The disk controller reads a logical command and translates the commands into multiple drive specific commands, including drive physical parameter information such as head, sector and cylinder selection. The calculation of these physical parameters is based upon a number of factors including the operating system installed in the computer system, the type of interleave scheme, if any, specified by the computer system configuration, and disk. specific parameters. The physical drive requests are then placed in a queue and executed by the microprocessor controller. The method also encompasses a method for creating a disk array configuration to be loaded on all disks within the array based on existing valid disk array information and configuration information maintained by the computer system.

Abstract: A method for detecting the presence of a replacement disk in a fault tolerant, intelligent mass storage disk array subsystem having a microprocessor based controller in a personal computer system and rebuilding the replacement disk independent of the computer system processor. The method calls for the microprocessor controller to run a disk array check at system powerup or at specified intervals at which will detect the existence of a replacement drive. The microprocessor then builds a series of disk drive commands which attempt to read every sector on the replacement disk. The read commands will return a null data read, indicating that the sector must be restored. The microprocessor controller converts the replacement read commands for all sectors on the replacement disk to write-restore commands. The microprocessor executes the write commands and restores the data to the replacement drive.

Abstract: A bus master interface command protocol for use with a computer system having an intelligent mass storage disk array subsystem, including a bus master and microprocessor controller. The command protocol permits the computer system to issue disk array commands to the controller at a logical level without having to issue disk specific commands. The disk array subsystem microprocessor controller reads the logical commands, translates the commands into smaller disk specific commands, and queues the disk specific commands for processing. Upon completion of the logical command, the bus master controller asserts control over the computer system bus and manages the transfer of data to or from the computer system memory. The management of the disk array subsystem and the transfer of data is effectively off-loaded from the system processor permitting more efficient use of the processor.

Abstract: A system for performing on-line reconfiguration of a disk array in which a source logical volume is reconfigured to a destination logical volume. Disk array configuration is invoked if a new physical drive is inserted, or a drive is removed. Reconfiguration can also be performed if the user desires to change the configuration of a particular logical volume, such as its stripe size. The disk array reconfiguration is run as a background task by firmware on a disk controller board. The reconfigure task first moves data from the source logical volume to a posting memory such as RAM memory. The reconfigure task operates one stripe at a time, with the stripe size being that of the destination logical volume. Once a stripe of data is moved into the posting memory, it is written back to corresponding locations in the destination logical volume. The reconfigure task continues until all data in the source logical volume have been moved into the destination logical volume. While the reconfigure task is working on a particular logical volume, data remains accessible to host write and read requests.
