I am getting problem while starting the CRS. Below is the necessary details:
1) I am using oracle 11g R2 RAC, with 2 node named RAC1 and RAC2
2) I have 3 diskgroup named DATA, DATA1, DATA2
3) OCR and voting disks are stored on ASM diskgroup
On node RAC1, CRS is started and /etc/oracle/ocr.loc is having the below entry:
On node RAC2, CRS is stopped and /etc/oracle/ocr.loc is having the below entry:
Please note the difference in “ocrmirrorconfig_loc”. The difference was occured because I updated the OCR location on RAC1 when RAC2 was down.
Now I am trying to repair the OCR on the RAC2 using below command. This command must be run as root user when HA service is started but CRS must be stopped.
ocrconfig -repair -replace +DAT2 -replacement +DATA1
but this showing error “PROT-21: Invalid parameter”, because to run this command diskgroup must be mounted. But diskgroup cannot be mounted until the CRS start. SO this is a conflicting situation.
Please suggest how to overcome from this problem ?
Please let me know if you required any other details.

Stop crs and start using following command
crsctl start crs -excl -nocrs
Then try ocrconfig restore . It should work

I am using 188.8.131.52, 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…
