003F Flash file system error detected
Event Type
Warning
Cause
A corrupted flash file system was found on the 3ware RAID controller during
boot-up.
The 3ware RAID controller stores configuration parameters as files in its
flash memory. These files can be corrupted when a flash operation is
interrupted by events such as a power failure. The controller will attempt to
restore the flash files from a backup copy.
Action
Update to the latest firmware, as earlier firmware resets corrupted files to
default settings.
We recommend using 3DM2, 3BM, or CLI to check your settings, in case
they were not able to be restored.
0040 Flash file system repaired

Information
Cause
A corrupted flash file system has been successfully repaired.
Some of the flash files with insufficient data may have been lost in the
operation. The configuration parameters which are lost will then return to
their default values.
Action
We recommend using 3DM2, 3BM, or CLI to check your settings, in case
they were not able to be restored.
