Event ID — 2289
Description Multi-bit ECC error on controller DIMM.
Severity Critical / Failure / Error
Cause and Action Cause: An error involving multiple bits has been encountered during a read or write operation. The error
correction algorithm recalculates parity data during read and write operations. If an error involves only a
single bit, it may be possible for the error correction algorithm to correct the error and maintain parity data.
An error involving multiple bits, however, usually indicates data loss. In some cases, if the multi-bit error
occurs during a read operation, the data on the disk may be OK. If the multi-bit error occurs during a write
operation, data loss has occurred.
Action: Replace the dual in-line memory module (DIMM). The DIMM is a part of the controller battery pack.
See your hardware documentation for information on replacing the DIMM. You may need to restore data
from backup.
