You have made some changes to oradg (e.g. created a new volume, or changed permissions of volume) and then run
SC 3.x: # scconf -c -D name=oradg,sync
SC 3.2 and above: # cldg sync oradg
The changes of the diskgroup oradg are now in sync with the cluster CCR


But if you do changes to another disk group in this example datadg before doing the 'cldg sync oradg' the following issues can occur:
 
A)
If you have previously renamed /dev/vx/dsk/datadg/vol to /dev/vx/dsk/datadg/vol2 via "vxedit rename" and you have NOT run "cldg sync datadg" but you now run "cldg sync oradg", then the following is observed in /var/adm/messages:
