Today I ran accross a system with a “Other Error Count: XX” assigned to the both drives in a raid 1 array. It took some googling but it turns out these are not ciritcal drive media errors, but some other SMART errors.

For reference here is a list of the LSI megaraid error codes and the corresponding SMART failure count (Thanks to the dell linux mailing list).

  • Predictive Failure Count == Number of SMART errors.
  • Media Error Count == Number of SMART errors related to the drive media.
  • Other Error Count == Number of SMART errors not related to the drive.

See wikipedia for the SMART error codes.
