Abstract: Method, system and computer program product for reporting and recovering from uncorrectable data errors in a data processing system using the Advanced Technology Attachment (ATA) or the Serial ATA (SATA) protocol. The invention utilizes the data scrubbing functionality of SCSI hard drives to provide a higher level of data integrity in an operating system implemented RAID environment. If an uncorrectable data error is found on a hard drive during a background data scrubbing operation, information concerning the data error is logged in a S.M.A.R.T. (Self Monitoring Analysis and Reporting Technology) error data structure. When the host operating system identifies the uncorrectable data error during normal operation, a Host Array Manager issues a Write Command to write the data from a redundant drive after the defective Logical Block Address (LBA) has been reassigned.

Abstract: A method, apparatus, and computer program product are disclosed for controlling accesses of drives in a storage subsystem. A first array of a first type of drive is provided. The first type of drive is a server class of drive. A second array of a second type of drive is provided. The second type of drive is a PC class drive. The first and second arrays are bound together to form a single array of drives. The single array of drives is presented to a host that is coupled to the storage subsystem as a single array. The host is unaware that the single array includes two different types of drives. Data is stored in the second array of drives. Data is migrated from the second array of drives to the first array of drives when an access rate of the second array of drives exceeds a threshold access rate for the second type of drive. The data that is chosen to be migrated from the second array to the first array is the data in the second array of drives that is accessed more frequently. Thus, frequently used data is accessed from the array of the first type of drives and less frequently used data is accessed from the array of the second type of drives.

Abstract translation: 公开了一种用于控制存储子系统中的驱动器的访问的方法，装置和计算机程序产品。 提供第一类驱动器的第一阵列。 驱动器的第一种类型是驱动器的服务器类。 提供第二类驱动器的第二阵列。 第二种驱动器是PC类驱动器。 第一和第二阵列绑定在一起以形成单个驱动器阵列。 将单个驱动器阵列呈现给作为单个阵列耦合到存储子系统的主机。 主机不知道单个阵列包含两种不同类型的驱动器。 数据存储在第二个驱动器阵列中。 当第二驱动器阵列的访问速率超过第二类驱动器的阈值访问速率时，数据从第二驱动器阵列迁移到第一驱动器阵列。 选择要从第二个阵列迁移到第一个阵列的数据是更频繁访问的第二个驱动器阵列中的数据。 因此，从第一类型的驱动器的阵列访问经常使用的数据，并且从第二类型的驱动器的阵列访问较少使用的数据。

Abstract: A system and method for managing parallel SCSI device functionality is presented. A user sends a request to a vendor whereby the request corresponds to the user changing the functionality of one of the user's SCSI devices. The vendor generates and sends a key that includes a password and a functionality value to the user. The user extracts the password, extracts the functionality value, and includes them in a command descriptor block. The user includes the command descriptor block in a SCSI command, and sends the SCSI command to the user's SCSI device whereupon the SCSI device validates the password and reconfigures itself based upon the functionality value. The SCSI device returns a message to the user indicating whether the reconfiguring process was successful. In turn, the user forwards the message to the vendor so the vendor may bill the user accordingly.
