         1 ce0             10.21.12.155     YES Oracle Cluster Repository
         2 ce1             172.6.12.160     NO  Oracle Cluster Repository
         2 ce0             10.21.12.159     YES Oracle Cluster Repository

2) select * from gV$CLUSTER_INTERCONNECTS;

decode  (PICKED_KSXPIA, 'OSD', 'OS dependent software', 'OCR', 'Oracle Cluster Repository', 'CI', 'cluster_interconnects parameter') FROM X$KSXPIA ;
INST_ID NAME_KSXPIA     IP_KSXPIA        DECODE(PUB_KSXPIA,'Y','YES','N   DECODE(PICKED_KSXPIA,'OSD','OS
---------- --------------- ---------------- -------------------------------- --------------------------------
         2 lan902          172.17.2.163     NO                               Oracle Cluster Repository
