0026 Drive ECC error reported

0027 DCB checksum error detected

276
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 274). 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
Tools> Check Now.
Under Linux or FreeBSD use
SATA device, substitute the correct drive letter and partition number, such as
sdb2, for sda1.

Event Type
Error
Cause
The drive's Drive Configuration Block (DCB) has been corrupted.
The 3ware RAID controller stores certain configuration parameters on a
reserved area of each disk drive called the Drive Configuration Block. As part
of power-on initialization, the 3ware RAID controller performs a checksum of
the DCB area to ensure consistency.
