FRAGMENTATIONINDEX specifies that the DEFRAG operation is to end if the fragmentation index is less than n, where n is a 1- to 3-digit number. DFSMSdss prefixes your number, n, with a decimal point. For example, 1 becomes .1, 999 becomes .999, 001 becomes .001, and so forth.

For additional information about the fragmentation index of a volume, see DEFRAG options.
