Yes. It's just within a resource set, the sequence in which you specify the resources in constraints is identical to that of groups, and the reverse of standard binary colocation constraints. Confused yet? The 6.16 example in shell syntax is as follows: colocation coloc-1 inf: ( A B C ) D Just enter that into the configuration, and then do "configure show xml coloc-1". Hope this helps.
