Hi,
Think a, b and c are 3 log files.
1,2 and 3 are log members of log file 'a'.
4,5,6 are log members of log file 'b'.
7,8,9 are log members of log file 'c'.
when log writer writes to log file 'a' then data written on member 1 and copy the same to 2 and 3.
When log switch occur it starts writing to log file 'b' and data is written on memeber 4 and copied to 5 and 6.
