638 Storage Management Alert Reference
2289 Multi-bit
ECC error.
Critical/
Failure/
Error
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, generally
indicates data loss. In some cases, if the multi-bit error
occurs during a read operation, then the data on the
disk may be OK. If the multi-bit error occurs during a
write operation, then data loss has occurred.
Action: Replace the dual in-line memory module (DIMM).
The DIMM is a part of the controller battery pack.
Refer to your hardware documentation for information
on replacing the DIMM. You may need to restore data
from backup.
754 None
2290 Single-bit
ECC error.
Wa rn ing/
Non-critical
Cause: An error involving a single bit has been
encountered during a read or write operation. The error
correction algorithm has corrected this error.
Action: None.
753 None
2291 An enclosure
management
module
(EMM) has
been
discovered.
OK/Normal/
Informational
Cause: This alert is provided for informational purposes.
Action: None.
851 None
2292 Communicati
on with the
enclosure has
been lost.
Critical/
Failure/
Error
Cause: The controller has lost communication with an
EMM. The cables may be loose or defective.
Action: Make sure the cables are attached securely.
Reboot the system.
854 None
2293 The enclosure
management
module
(EMM) has
failed.
Critical/
Failure/
Error
Cause: An EMM has failed. The failure may be caused
by a loss of power to the EMM. The EMM self test may
also have identified a failure. There could also be a
firmware problem or a multi-bit error.
Action: Replace the EMM. See the hardware
documentation for information on replacing the EMM.
