Upgrade oracle grid infrastructure from 11g to 12C

          Below are steps for upgrading Oracle grid infrastructure from 11.2.0.4 to 12.1.0.2

PRECHECK:

1. Check the active version:[ from grid owner]
crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [11.2.0.4.0]

2.Collect the crs status by running below commands[ grid owner]

/crsapp/app/oracle/product/grid/bin/crsctl check crs
/crsapp/app/oracle/product/grid/bin/crsctl stat res -t
/crsapp/app/oracle/product/grid/bin/crsctl stat res -p
/crsapp/app/oracle/product/grid/bin/oifcfg iflist -p -n
/crsapp/app/oracle/product/grid/bin/oifcfg getif
/crsapp/app/oracle/product/grid/bin/ocrcheck

3. Take backup of OCR:

./ocrconfig -export /softdump/BACKUP/pre_upgrade_backup/ocr_file

4. Download the copy the 12c grid software to the server:

-rwxr-xr-x 1 oracle oinstall 33934 Aug 24 2015 readme.html
drwxr-xr-x 4 oracle oinstall 16 Dec 18 12:44 install

5. Run the cluvfy script for precheck:

./runcluvfy.sh stage -pre crsinst -upgrade -rolling -src_crshome /crsapp/app/oracle/product/grid11204 -dest_crshome /crsapp/app/oracle/product/grid12c -dest_version 12.1.0.2.0 -fixup -verbose

Find the output here:   cluvfy_output

Make sure the cluvfy executed successfully. If any error, please take action before proceeding.

6. Unset all the environment variables:

unset ORACLE_BASE
unset ORACLE_HOME
unset ORACLE_SID
unset ORA_CRS_HOME
unset ORA_NLS10
unset TNS_ADMIN
env |grep ORA

7. Stop the database/services running in grid

srvctl stop database -d DBAPROD

8. Take backup of Grid binary:

tar -cvf grid_home_preupg.tar $GRID_HOME

UPGRADE:

9 . Now start the upgrade using runInstaller

[+ASM1@sec60-2]/export/home/oracle# crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [12.1.0.2.0]

  6. in my case during upgrade when we run rootupgrade.sh script on local node. The node is shut down and cluster is down now. second node was also down and cluster is down. how we can make cluster up and continue upgrade further. Can you advise.

    1. Rootupgrade.sh script should take care of everything. Please let us know if it is reporting any other error.??

  7. when we run the script at node-1 it suspends the VM node and keep suspended situation and need to to restart the node-1 to come up again. Thus not completing the upgrade.
