only select the FCP devices whose PCHIID has free capacity

Examples:

free capcity of PCHIDs =  {'A':1, 'B':3, 'C':2, 'D':2}

                             |--- PCHID ----|   
FCP combinations                A    B    C    D        weight  valid(>=1)
---------------------------------------------------------------------------
1a01(A) 1b01(A) 1c01(C)    min( 0.5       2        )  = 0.5     No
1a02(A) 1b02(B) 1c02(C)    min( 1    3    2        )  = 1       Yes   --|___ random select one
1a03(A) 1b03(D) 1c03(D)    min( 1              1   )  = 1       Yes   --|
