VCS Database Service Group Service Group Fails After Initiating Offline

You have an issue here. Three resources that are really referring to the same diskgroup. So if one offlines the DG the other will fault.

CVMVolDg cvmquorum (

                                    CVMDiskGroup = oradgredolog1

                                    CVMVolume = { volredolog1 }

                                    CVMActivation = sw

                                    )

                  CVMVolDg cvmredolog1 (

                                    CVMDiskGroup = oradgredolog1

                                    CVMVolume = { volredolog1 }

                                    CVMActivation = sw

                                    )

                  CVMVolDg cvmredolog2 (

                                    CVMDiskGroup = oradgredolog1

                                    CVMVolume = { volredolog1 }

                                    CVMActivation = sw

                                    )

Is your Oracle voting disk on /ocr or /voitng - if so this is your issue - you need to move this CFSMount and CVMVolDg resource to cvm group and add a cssd resource so you have something like below:

If you bring down voting disk before stopping cssd, Oracle will panic the box - you should be able to confirm this from the system log which should show that Oracle paniced the server
