Suppose that you have prepared servers including two database servers, storage and name server. Now you are ready to go on installing grid infrastructure.
Please note that, I have put all lengthy configuration work in the previous post, so we don’t need to configure anything in this post. All we have to do is to install grid infrastructure. That is to say, our job is clearly separated into two main parts, one is configuration, the other is installation.
Install Grid Infrastructure
Starting with Oracle Grid Infrastructure 12c Release 2 (12.2), installation and configuration of Oracle Grid Infrastructure software is simplified with image-based installation.
[grid@primary01 ~]$ cd $ORACLE_HOME
[grid@primary01 grid]$ ./gridSetup.sh
Scanning no disk can be a very serious problem in this step. If you found no disk is listed in all possible discovery paths, it might be because ASMLib scanned no disks after server reboot. Or probably another complicated issue, which is caused by improper sector sizes of your storage.
