| Step 1 |
The Ansible installation playbooks for OpenShift should by default install the iscsi-initiator-utils package. Verify that the package is installed.
Scope:
Run on all OpenShift nodes.
Command:
sudo yum list installed iscsi-initiator-utils
Example:
administrator-host:hxkube$ cat ~/hxkube/ocp_nodes.txt | while read host; \
do ssh -n $host sudo yum list installed iscsi-initiator-utils; \
done

| Step 2 |
If, for some reason, the iscsi-initiator-utils package is not installed, install it using the yum package manager.
Scope:
Run on all OpenShift nodes.
Command:
sudo yum install -y iscsi-initiator-utils
Example:
administrator-host:~/hxkube$ cat ~/hxkube/ocp_nodes.txt | while read host; \
do ssh -n $host sudo yum install -y iscsi-initiator-utils; \
done
administrator-host:~/hxkube$
|
| Step 3 |
Install the avahi-autoipd package using the yum package manager.
Scope:
Run on all OpenShift nodes.
Command:
sudo yum install -y avahi-autoipd
Example:
administrator-host:hxkube$ cat ~/hxkube/ocp_nodes.txt | while read host; \
do ssh -n $host sudo yum install -y avahi-autoipd; \

| Step 4 |
In the Deploying RedHat OpenShift Container Platform section, you were instructed to add an additional virtual machine network interface to each OpenShift node. The interface
name of the added virtual machine network interface is now required in order to proceed with the installation.
Use the ifconfig -a command to find the name of the interface on one of the OpenShift nodes. The interface should not have an IP address assigned
and it is recommended to cross reference the MAC address with VMware vCenter in order to ensure the correct interface. In
this particular environment the added interface is named ens224.
| Note
|
The ifconfig -a command only needs to be run on a single OpenShift node.
|
Scope:
Run on a single OpenShift node.
Command:
sudo ifconfig -a

| Step 5 |
Ensure there is no network configuration file (/etc/sysconfig/network-scripts/ifcfg-<interface_name>) for the additional virtual machine network interface that was added for the HyperFlex Storage Integration for OpenShift.
Scope:

done
administrator-host:~/hxkube$
|
| Step 9 |
Edit the /etc/kubernetes/hxflexvolume.json configuration file to change the target IP address from 169.254.1.1 to 169.254.254.1.
Command:
sudo sed -i -e s/169.254.1.1/169.254.254.1/ /etc/kubernetes/hxflexvolume.json.example
Example:
