app-ipmp0 global public

loypredbib0 global cluster_interconnect

loypredbib1 global cluster_interconnect




select NAME,IP_ADDRESS from v$cluster_interconnects;

9. Check CRS status of local node 

crsctl check crs


CRS-4638: Oracle High Availability Services is online

CRS-4537: Cluster Ready Services is online

$GRID_HOME/bin/crsctl stat res -t

$GRID_HOME/bin/crsctl stat res -t -init

11. Check active version of cluster

crsctl query crs activeversion

Oracle Clusterware active version on the cluster is []

12. Stop and start high availability service ( HAS)

crsctl stop has


crsctl start has

13. Check CRS status of remote nodes

crsctl check cluster


crsctl check cluster -all

14. Disk timeout from node to voting disk(disktimeout)

crsctl get css disktimeout

CRS-4678: Successful get disktimeout 200 for Cluster Synchronization Services.

15.Network latency in the node interconnect (Misscount)

crsctl get css misscount

CRS-4678: Successful get misscount 30 for Cluster Synchronization Services.

16. Move voting disk to another diskgroup:

crsctl replace votedisk +OCRVD

18. Delete voting disk:

crsctl delete css votedisk

19. Get ocr disk backup details

ocrconfig -showbackup

20. Check whether standard or flex ASM

crsctl get cluster mode status


Cluster is running in “standard” mode
