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. 15 October, 2011 at 5:32 am #2158 Amit BansalKeymaster Pankaj, Stop crs and start using following command crsctl start crs -excl -nocrs Then try ocrconfig restore . It should work -Amit 17 October, 2011 at 7:08 am #2159 Pankaj SharmaParticipant Hi Amit, 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… Author Posts You must be logged in to reply to this topic.
