What is Cluvfy?
Prior to 11gR2 we would probably use the "runcluvfy.sh" utility in the clusterware root directory to check the prerequisites have been met. If you are intending to configure SSH connectivity using the installer this check should be omitted as it will always fail. If you want to setup SSH connectivity manually, then once it is done you can run the "runcluvfy.sh" with the following command.
You must go to the location like "/mountpoint/clusterware/" in mycase it was "/u01/grid"......then you run command something like below
"sh runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose"
You may have to troubleshoot errors before proceeding to clusterware installation.
1, "./runInstaller" trigger this command to start Oracle Clusterware Installation.
2, Select the "Install and Configure Grid Infrastructure for a Cluster" option, then click the "Next" button.
3, Select the "Typical Installation" option, then click the "Next" button.
4, On the "Specify Cluster Configuration" screen, enter the SCAN name in my case it is "rac-scan" , if you don't know or confused what could be SCAN name then please check "/etc/hosts" file and click the "Add" button.
5, Enter the details of the second node in the cluster, in my case it is like "rac2.sunmerge.com" "rac2-vip.sunmerge.com" then click the "OK" button.
6, Click the "SSH Connectivity..." button and enter the password for the "oracle" user. Click the "Setup" button to to configure SSH connectivity, and the "Test" button to test it once it is complete.
7, Enter "/u01/app/11.2.0/grid" as the software location and "Automatic Storage Manager" as the cluster registry storage type. Enter the ASM password and click the "Next" button.
8, Set the redundancy to "External". if the ASM disks are not displayed, click the "Change Discovery Path" button and enter "/dev/oracleasm/disks/*" and click the "OK" button. Select all 5 disks and click the "Next" button.
9,Accept the default inventory directory by clicking the "Next" button.
10, Wait while the prerequisite checks complete. If you have any issues, either fix them or check the "Ignore All" checkbox and click the "Next" button.
11, If you are happy with the summary information, click the "Finish" button.
12, Wait while the setup takes place.
