Those are all priv set diag commands.
CNA is for information on FCoE adapters
VTIC has to do with ALUA and FC multipathing, it is what allows multipathing failover to occur non-disruptively(my guess at least, given that stand alone systems without ALUA enable do not report vtic in igroup show -v).
The rest follow their Unix counterparts, and outside "cna show" and "vtic get_names" I have never used the others because diag commands are potentially dangerous.
