Description
A block on the physical disk has been punctured by the controller.
Severity Critical / Failure / Error
Cause and Action Cause: The controller encountered an unrecoverable medium error when attempting to read a block on the
physical disk and marked that block as invalid. If the error was encountered on a source physical disk during
a rebuild or reconfigure operation, it also punctures the corresponding block on the target physical disk. The
invalid block is cleared during a write operation.
Action: Back up your data. If you are able to back up the data successfully, initialize the disk and restore
from the back up.
