IPLB loads the RIAT into storage along with all the other main storage resident chained tables (FCTB, IPAT, SIGT, and others).
CTIN places the address of each subsystem's RIAT in the CINFC area of the subsystem in the slot addressed by CINFC tag CMMRIT.
CTIN also builds the hash table in the first part of the RIAT and sets up all addresses in both parts of the RIAT.
