You can use the following workarounds:

  • Use the following command to force the siteconsistency for the DCL volume:

    vxvol -g disk_group -f set siteconsistent=on volume_dcl 
  • If the first solution doesn't work, recreate the DCO object. You must set the  siteconsistency for the disk group and volume before you recreate the DCO object.

    Remove the DCO. Enter:

    vxsnap -g disk_group  -f unprepare volume

    Create the DCO. Enter:

    vxsnap -g disk_group prepare volume

    Verify the DCO version. Enter:

    vxprint -g disk_group_name -m dco_name

    The version value should look similar to the following:


    Use the following command to fix the problem. Enter:

    vxvol -g dw -f set siteconsistent=on log_volume

Note: Symantec recommends that you upgrade the product. This problem is fixed in Release 5.1 SP1.
