    Hi,

    Sorry for the late reply.

    Amit:- This is external redundancy group.

    Saurabh:- That time I recovered the vote disk by restoring it. But just to get answer of your question, I have simulate the failure again, so that we can find out the reason for this unexpected behaviour of clusterware.

    This time my votedisk was on ASMDISK3 and corresponding os deveice is “/dev/sdd1”

    [BEFORE FAILURE]

    Below is the output from command “$ kfed read /dev/sdd1”

    Disk “ASMDISK3” defines an unmarked device

    Still the same findings as before like no error message, vote disk are still ONLINE.

    Let me know if you want any other information.

    Hi Amit,

    I am using 11.2.0.1, so I used “crsctl start crs -excl”, it worked for me perfactly. I shutdown the CRS on all other nodes and from node2, i used the below command:

    ocrconfig -repair -replace +DATA2 -replacement +DATA1

    Now, all ocr.loc have the same entry on all nodes and I started the cluster on all nodes.

    Thanks a lot…
