[Oracle RAC 12.1 SHARED FILE SYSTEM Installation]: Checking cluster configuration before RAC installation

Server: rac1


Perhaps it’s better to download the latest version of “Oracle Cluster Verification Utility” from the Oracle website

# cd /tmp/oracle/12.1/database/rpm
# rpm -Uvh cvuqdisk-1.0.9-1.rpm



# su - oracle12
$ cd /tmp/oracle/12.1/grid



$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -r 12.1

If errors occur, you can get a log with a more detailed report of the issues:

$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -r 12.1  -verbose > /tmp/log.log


Got an error:

Add:

Pre-check for cluster services setup was successful.

Since I work with virtual machines, I think it’s necessary to save (create a snapshot).
