Error Messages Log

Question

Where does DataKeeper log error messages?

Answer

DataKeeper events are logged in the Windows Application Event Log and the Windows System Event Log. Here is a breakdown of the messages you can look for.

Application Event Log:

• Source = ExtMirrSvc – events related to the DataKeeper service.

• Source = DataKeeperVolume – events related to DataKeeper Volume Resources defined in Windows Failover Clustering (WSFC).

• Source = SIOS.SDRSnapIn – events related to the DataKeeper GUI connecting to the DataKeeper systems.

System Event Log:

• Source = ExtMirr – events directly related to mirror creation, mirror manipulation and replication.

*Note: The System Event Log should always be set to “Overwrite events as needed”. If the System Event Log fills up or becomes corrupted, it will prevent DataKeeper from properly recognizing mirror state changes.
