  • Page 97: Capacity Expansion And Extension

    8 Capacity expansion and extension Array expansion is the addition of physical hard drives to an array that has already been configured. The capacity of these added physical hard drives may then be added to an existing LUN on the array or configured into a new LUN.
  • Page 98 Capacity expansion and extension...
  • Page 99: Hard Drive Failures And Faulted Luns

    9 Hard drive failures and faulted LUNs The purpose of fault-tolerant array configurations is to protect against data loss due to hard drive failure. Each RAID configuration has inherent limitations on the number of hard drive failures that it can tolerate. If the fault-tolerance level of a particular LUN or array configuration is exceeded, the array will be locked from any further I/O.
  • Page 100: Compromised Fault Tolerance

    • 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.
  • Page 101: Best Practices When Replacing Hard Drives

    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 102: Automatic Data Recovery (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 103: 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.
