Troubleshooting Error and Notification Message Details 0001 Controller reset occurred Event Type Information Cause The device driver has sent a soft reset to the 3ware RAID controller. The driver does this when the controller has not responded to a command within the allowed time limit (30 sec.). After the soft reset command has been sent, the driver will resend the command. Action If this message occurs more than three times a day, collect the system logs and contact Technical Support. See Also For how to collect the system logs, see http://www.3ware.com/kb/ article.aspx?id=12278 For more information regarding FreeBSD installation, see KB articles 14850: http://www.3ware.com/kb/article.aspx?id=14850 0002 Degraded unit Event Type Error Cause An error was encountered and the unit is now operating in degraded (nonredundant) mode. This is usually due to a drive failure or the physical removal of a drive from a redundant unit. Action Check hardware connections and reseat the drive or drives. Rescan the controller from 3DM or CLI to see if the unit has been restored. If you are able to restore the unit before any data has been written to the unit, a rebuild will not be necessary. If the unit remains degraded, replace the missing or dead drives and initiate a rebuild. 264 3ware SAS/SATA RAID Software User Guide, Version 9.5.1
