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 250). 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.
For Mac OS X, you can use the First Aid tab in the Disk Utility—select the
disk on the left and then click Verify Disk. If verification encounters
problems, you can then use the Repair Disk option on the same screen.
Under Linux and FreeBSD use the fsck command.
For OpenSolaris and VMware you should follow your operating system’s
guide to perform a file system check.
