Error and Notification Messages

Background Information
The 3ware RAID controller uses caching layer firmware to improve
performance. For write commands this means that the controller
acknowledges it has completed a write operation before the data is committed
to disk. If the 3ware RAID controller cannot commit the data to the drive after
it has acknowledged to the host, this message is posted.
Action
To troubleshoot the reasons for the failure, collect the logs for your system
and contact 3ware technical support at http://www.lsi.com/channel/
ContactUs. For information on collecting logs, search the LSI Knowledge
Base for keyword 12278 (use the Advanced Search) at

0026 Drive ECC error reported
Event Type
Error
Cause
Drive ECC errors are an indication of grown defects on a particular drive. For
redundant units, this typically means that dynamic sector repair has been
invoked (see message “0023 Sector repair completed” on page 261). For non-
redundant units (Single Disk, RAID 0 and degraded units), which do not have
another copy of the data, drive ECC errors result in the 3ware RAID
controller returning failed status to the associated host command.
Action
Schedule periodic verifications of all units so that drive ECC errors can be
found and corrected. If the unit is non-redundant a unit file system check is
recommended.
Under Windows, right-click on your drive icon and choose
Properties>
Tools> Check Now.
Under Linux use fsck /dev/sda1. If you have more than one SATA device,
substitute the correct drive letter and partition number, such as sdb2, for sda1.
