Nothing to worry about here. Controller IDs (c<n>) are assigned
based on the order the kernel probes the hardware. On the SPARC
systems you can usually change this in the firmware (OBP), but they
really don't _mean_ anything (other than the kernel found c8 before it
found c9).
There are (or were) other things the kernel considers a "disk
controller" on the system beyond the three you indicate. Keep in mind
that once the kernel finds a controller it makes an entry in
/etc/path_to_inst so that the IDs remain consistent if new controllers
are added (earlier in the search path).
