0008 Unclean shutdown detected
0009 Drive timeout detected
www.3ware.com
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.

Event Type
Error
Cause
A drive has failed to respond to a command from a 3ware RAID controller
within the allowed time limit (20 secs.). After sending this error message, the
controller will attempt to recover the drive by sending a reset to that drive and
retrying the failed command.
Possible causes of drive time-outs (also known as ATA-Port time-outs)
include a bad or intermittent disk drive, power cable or interface cable.
Action
If you have checked hardware connections and no cause other than the drive
can be found, replace the drive.
You may also want to use the drive manufacturer's diagnostic and repair
utilities on the drive.
