Every fileset also has a fileset ID number that, like a fileset name, is unique within the cell in which the fileset resides. When a fileset is registered in the FLDB with the fts create or fts crfldbentry command, the FL Server allocates it a fileset ID number, which is stored in the FLDB along with its name. Read/write and backup filesets have their own fileset IDs, which are automatically reserved in the FLDB when the read/write source fileset is registered; all read-only copies of the same read/write fileset share a common fileset ID.
Fileset ID numbers are represented as two positive integers separated by a pair of commas. For example, the ID number of the first fileset in the FLDB is 0,,1. The integer after the commas is then incremented every time a new fileset is created. When the integer after the commas becomes larger than 2-to-the-32nd-power, the integer before the commas becomes 1 and the integer after the commas returns to 0 (zero).
When specifying a fileset ID in a DFS command, you can omit the integer before the commas if it is a 0 (zero); commands that accept a fileset ID number assume that the first integer is 0 (zero) if it is not supplied. In this case, also omit the two commas. For example, the fileset ID number 0,,1 can be entered as 1.
