You need both the SDD package and the host attachment scripts. In case of ESS with FC which I assume you have this would be devices.fcp.disk.ibm2105.rte. With parallel SCSI connection replace fcp with scsi.

AIX 4.3 to 5.2 ...the san disk naming convension is vpath.....later version ie 5.3......it will show as hdisk

Is that the case
I am afraid not. You can convert vpath to hdisk if you don't want to use vpath devices. But SDD naming convention did not change and most likely won't change in the future as both ESS and SDD are not developed any further.
