800xA History Storage Full
In our system we have 800xA history (single server).
We are in commissioning step and logged unimportant event in historian server and storage has been full.
Now histrory server storage (Drive D) is full.
Please guide me about 800xA history cleanup storage procedure.
I believe I've heard that a full disk may become a problem to 800xA History and cause premature wrapping of data. Care must be taken to not fill its data drives.
My areas of expertise in ABB historians are Basic History and IM History, both pre-allocating storage space at time of creation of logs to avoid problems of a full disk (to be honest: the IM's Oracle database instance may need to auto-extend its files on disk until the database tables have sized themselves to meet the amount and mixture of OPC messages and attributes (which may vary); this is hard to predict but will be known as soon as the logging has reached its capacity and older events are being overwritten).
