Hi,

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:

ocrconfig_loc=+DATA

ocrmirrorconfig_loc=+DATA1

On node RAC2, CRS is stopped and /etc/oracle/ocr.loc is having the below entry:

ocrconfig_loc=+DATA

ocrmirrorconfig_loc=+DATA2

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.

Pankaj,

Stop crs and start using following command

crsctl start crs -excl -nocrs

Then try ocrconfig restore . It should work

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…
