Error and Notification Messages 0007 Initialize completed Event Type Information Cause The 3ware RAID controller completed the "synching" background initialization sequence of RAID levels 1, 6, 10, 50, or 5. For RAID 5, RAID 6, and RAID 50, the data on the unit was read and the resultant new parity was written. For RAID 1 and 10, one half of the mirror was copied to the other half (mirrors are synchronized). This message will not appear for a foreground initialization. See Also "Foreground Versus Background Initialization" on page 159 0008 Unclean shutdown detected Event Type Warning Cause The 3ware RAID controller detected an unclean shutdown of the operating system, either from a power failure or improper shutdown procedure. The controller will force the unit to begin verifying, due to the possibility that data on a redundant unit could be out of synchronization. Action Allow the verification to complete. Verifications have little overhead in terms of system performance and keep your units in optimum condition. To prevent unclean shutdowns, always go through the normal shutdown procedure. It is also recommended to use an uninterruptible power supply (UPS) to prevent unclean shutdowns due to sudden power loss. See Also "About Verification" on page 162 www.3ware.com 267
