X'01'

There are three situations in which X'6701' is written:

• A /TRACE command was issued. This record can also indicate that error blocks were written unconditionally by device-dependent code when a major error condition was detected (DFSCFEZ0).

The customer can then process these log records to determine what action to take for these UOWs. (DFSSQ030, DBFSQ030)
