  • Page 37: Compromised Fault Tolerance, Recovering From Compromised Fault Tolerance, Factors To Consider Before Replacing Hard Drives

    Compromised fault tolerance If more hard drives fail than the fault-tolerance method allows, fault tolerance is compromised, and the logical drive fails. In this case, all requests from the operating system are rejected with unrecoverable errors. You are likely to lose data, although it can sometimes be recovered. One example of a situation in which compromised fault tolerance may occur is when a drive in an array fails while another drive in the array is being rebuilt.

  • Page 38: Automatic Data Recovery (rebuild), Time Required For A Rebuild, Failure Of Another Drive During Rebuild

    • If the offline drive is a spare, the degraded drive can be replaced. • Do not remove a second drive from an array until the first failed or missing drive has been replaced and the rebuild process is complete. (The rebuild is complete when the Online LED on the front of the drive stops blinking.) Exceptions: •...

  • Page 39: Drive Failure In A Netware Environment, Failed Drives Or Interim Recovery Mode

    If this situation occurs, restart the server. The system may temporarily become operational long enough to allow recovery of unsaved data. In any case, locate the faulty drive, replace it, and restore data from backup. Drive failure in a NetWare environment Use CPQONLIN to identify and monitor drive failure status in a NetWare environment.

  • Page 40

    NOTE: NetWare cannot detect a single physical drive failure when using hardware-based fault tolerance. NetWare determines that the data is still valid and accessible during the rebuilding process. However, the driver knows that a physical drive has failed. A message is printed on the console notifying the user that a physical drive is in a degraded state.
