Related with LSC_LOCK guardian change, the number of locked state is different from before.
I modified the configuration of make15minSegment.py script.

The state definition is as follows:
K1:GRD-LSC_LOCK_STATE_N != 10000: K1-GRD_UNLOCKED_SEGMENT_UTC_yyyy-mm-dd
K1:GRD-LSC_LOCK_STATE_N == 10000: K1-GRD_LOCKED_SEGMENT_UTC_yyyy-mm-dd

For technical reason, LOCKED segmets are generated from the opposite of UNLOCKED segments (klog 13303).
