The 'c' is for "controller", and the number that follows is one that is assigned to the given controller (not necessarily on a first-come- first-served 0-based basis!). The controller number should be considered unpredictable at install time. Once installed it shouldn't change, except for removable disks, where the controller number might vary according to which slot you plugged the disk into. The 't' is for "target". The 'd' is for "disk" -- think LUN. The 'p' is for "partition", and is used in Solaris on x86. The 's' is for "slice". Slices are like partitions, but only used in SOLARIS2 partitions, of which you're allowed no more than one per-disk.
