startup the cluster in exclusive mode, then log into ASM and show the status here (select * from v$asm_disks; and select * from v$asm_diskgroup;)
I assume, you have to mount the diskgroup with force (since one disk is missing) and drop the not existing disk, then add the new one.
when u say start cluster --> I assume you are re starting the resources, correct.
Since you were adding disk / remove disk from ASM, ASM needs to be up.
So not sure what you mean exactly by "start cluster --> FAILED because ASM was not able to mount the OCR diskgroup. It was still looking for the ASM_D40_39 disk in order to mount properly.".
Did you stop all clusterware resurce and restart or just restarting resources or what.
So the exact sequence of events is not clear.
Not enough information here, but,check on the following:
1. Is that disk visible on the other nodes of the cluster as one would expect.
2. Is that disk being use for the voting disks. Use "crsctl query css votedisk". I seriously doubt it since the clusterware is still up.
I did not say start cluster. I said start cluster in exclusive mode. That is "crsctl start -excl"
With this the clusterstack will come up, without the requirement of having access to OCR and Voting. See documentation on how to restore OCR and vote.
This will also help you to startup ASM without having to mount the main diskgroup, and this allows you to do maintanance on the ASM diskgroups (like force mounting etc.) Note: Exclusive also says that you can do this exclusively on one node, not on all.
