Hi one and all,

Please help me out, how to refresh mirrored Voting Disk for HA.

As reference of Oracle documentation we can give mirror OCR & Voting Disk for High Availability, but in my machine mirror OCR is working fine it will refreshing on both location, but not VD.

see below command:
root:crs/bin] # crsctl add css votedisk /ocr_disk/HA_vote02.dbf
Now formatting voting disk: /ocr_disk/HA_vote02.dbf
successful addition of votedisk /ocr_disk/HA_vote02.dbf

After couple of minutes I saw, it will not refreshing HA_vote02.dbf

ariepdb1[/ocr_disk] #ls -l
