These errors have been identified since the installation.
They seem to occur around 1:00 AM every day.
There have been no onsite environmental changes reported.
Both nodes have been reseated as these are IOM12E modules, but this has not made any changes.
As of now there does not seem to be any ongoing issues with the storage, cause of error is to be confirmed.
