Overview
Following the successful creation of two (2) VM images under XEN with OEL7 and using the revised network design, I now go ahead with the installation of Grid Infrastructure 12.1.0.2 on that cluster.

Preparation for Installation
Pre-installation RPM Installed
Following the procedure in 3.2 Installing the Oracle Preinstallation RPM From Unbreakable Linux Network , I ran the following command on both REDFERN1 and REDFERN2 (assuming what is valid for OEL6 is also valid for OEL7):
yum install oracle-rdbms-server-12cR1-preinstall
There was a large amount of output which I did not capture, but the installation appeared to be successful.
Changed ORACLE Password
Changed the password for the oracle user on both REDFERN1 and REDFERN2 .
Permanently Change Host Name
Unfortunately, the use of hostname does not permanently change the hostname. I had to do the following (as root ) on REDFERN1 , and a similar thing on REDFERN2 :
cat >>/etc/sysctl.conf <<DONE kernel.hostname = redfern1.yaocm.id.au DONE reboot
Create Oracle GI Software Home
Create the Oracle Grid Infrastructure Software Home as follows on both REDFERN1 and REDFERN2 :
sudo mkdir /opt/app/grid_infra sudo chown oracle:oinstall /opt/app/grid_infra
Installed OEM Agent
From CRONULLA , the OEM agent was pushed out to both REDFERN1 and REDFERN2 . I ignored the warning about RHEL 7 not being supported.
Change Ownership for Shared Disks
Ran the following command to change the ownership of the shared disks so that they can be discovered by ASM:
sudo chown oracle:dba /dev/xvd[d-h]
The ownership of these shared disks was verified as follows:
ls -l /dev/xvd[d-h]
And the ouput is:
brw-rw----. 1 oracle dba 202, 48 Jan 1 20:48 /dev/xvdd brw-rw----. 1 oracle dba 202, 64 Jan 1 20:48 /dev/xvde brw-rw----. 1 oracle dba 202, 80 Jan 1 20:48 /dev/xvdf brw-rw----. 1 oracle dba 202, 96 Jan 1 20:48 /dev/xvdg brw-rw----. 1 oracle dba 202, 112 Jan 1 20:48 /dev/xvdh
Locate GI Software
Instead of unloading the GRID software onto the local host, I now use the NFS directory as set up through Use NFS for Oracle Software .
Start Installation
From PENRITH , I ran the following commands in an XTerm session:
xhost + 192.168.1.140 ssh -Y oracle@192.168.1.140
Once on REDFERN1 , I ran the following commands:
cd /opt/share/Software/grid/linuxamd64_12102/grid ./runInstaller

Correct Size of VOTE Disk
Shutdown REDFERN Cluster
I shutdown the REDFERN cluster.
Increased Size of VOTE Disk Group
On VICTORIA , I increased the size of the shared VOTE_01 disk as follows:

Start Up REDFERN Cluster
The REDFERN cluster was then started.
Change Disk Ownership
