    Note It is important to be aware of the distinction between the occurrence of a failure and the reporting of that failure. A disk array component failure is reported immediately to the disk array. The disk array, in turn, notifies the system of this event when the next I/O is attempted to any disk array component .

    Disk Module Removal and Replacement Caution NEVER remove or replace faulted disk modules when array power is OFF as data can be lost. NEVER rearrange faulted disk modules when array power is either ON or OFF as data can be lost. Handle disk modules very carefully as they can be damaged easily by shock and vibration.

  • Page 328

    Note With the redundant RAID levels of RAID-5, RAID-3, RAID-1/0, and RAID-1, only one disk module should replaced at a time, and each rebuild should complete before another disk module is replaced. When using RAID-5, RAID-3, RAID-1/0, or RAID-1, a rebuild begins as soon as a disk module is replaced.

    In a single-SP configuration, data will be lost if the SP is not disabled and the unposted data is not written to disk before the SP is removed. In a two-SP configuration, the data is mirrored so the data is preserved. Hewlett-Packard recommends that the cache be disabled before an SP is removed.
