    • RAID 6 configurations can tolerate simultaneous failure of two hard drives in the array. Compromised fault tolerance Each RAID configuration has inherent limitations on the number of physical hard drive failures that it can tolerate. If more hard drives fail than the fault-tolerance method allows, fault tolerance is compromised. When the MSA determines that the fault tolerance of a LUN is compromised, the LUN is taken offline and subsequent I/O requests are rejected.

    b. Make copies of important data, if possible. Replace any failed hard drives and allow the Automatic Data Recovery (ADR) process to rebuild the data onto replacement drives. d. After failed hard drives have been replaced, fault tolerance may again be compromised. If so, power cycle the system, and if the #02 or #04 ENABLE VOLUME LCD message is displayed, press the right push button to re-enable the LUNs.

  • Page 100: Time Required For A Rebuild

    • When RAID 6 (ADG) is used, two drives can fail simultaneously (and be replaced simultaneously) without data loss. • If the offline drive is a spare, the degraded drive can be replaced. • Do not remove a failed second hard drive from an array until the first failed or missing hard drive has been replaced and the rebuild process is complete.

  • Page 101: Failure Of Another Drive During Rebuild

    Failure of another drive during rebuild If a non-correctable read error occurs on another physical drive in the array during the rebuild process, the Online LED of the replacement drive stops blinking and the rebuild abnormally terminates. If this situation occurs, restart the server and the storage system. The system may temporarily become operational long enough to allow recovery of unsaved data.

    A Regulatory compliance and safety Regulatory compliance Federal Communications Commission notice Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules.
