Abstract

A RAID storage-device-assisted unavailable primary data/Q data rebuild system includes a RAID primary data drive that receives a RAID storage controller device command and DMA's first primary data to a RAID parity data drive. The RAID parity data drive receives a RAID storage controller device command and XORs its first parity data, the first primary data, and its second primary data to produce third primary data that it writes to its storage subsystem. The RAID parity data storage device then receives a RAID storage controller device command and performs GF and XOR operations on the first primary data, the second primary data, and the third primary data to produce second Q data, and DMA's the first Q data to a RAID Q data drive. The RAID Q data storage device receives a RAID storage controller device command and writes the first Q data to its storage subsystem.
