Performing the OS installation

To install the appliance on a node:

In Virtual Machine Manager, double-click the new HCP VM node.
Enter the KVM host password.
After the virtual machine starts, either press Enter or let the program default to the installation option after 75 seconds.
The installation program prompts whether to preserve or clear existing storage volumes.
```
P) Preserve storage volumes during installation
C) Clear storage volumes during installation
E) Exit the installation

Type your selection and press enter [pce]:
```
Enter c to clear existing storage volumes.

In response to the confirming prompt, enter y.

You have chosen to clear the storage volumes
THIS OPTION WILL DESTROY ANY DATA ON THE STORAGE VOLUMES.
Are you sure you want to clear the storage volumes 
y/n):

When prompted, enter the front-end network IP mode for the KVM host. The IP mode that you specify is used to set both the system-level IP mode and the [hcp_system] network IP mode.
Enter the front-end network IP mode ([IPv4], IPv6, Dual):
If the installer detects both BaseT and SFP+ network interface cards in this system, you are prompted to enter the front-end network interface types for the HCP system.
Enter the front-end network interface type ([BaseT], SFP+)
When prompted, enter y to use a VLAN ID, or enter n if you don’t want to provide a VLAN ID.
Do you want to provide a VLAN ID for the front-end network? [n]:
If you entered IPv4 or Dual in response to the prompt in Step 6, specifythe IPv4 HCP VM node IP address, subnet mask, and gateway IP address for the front-end network; otherwise, go to Step 10.
1. When prompted, enter the IPv4 address assigned to the HCP VM node for the front-end network.
  
  Important: Do not enter the front-end IP address for the KVM host. Enter the front-end network address for the HCP VM node.
```
Enter the front-end IPv4 IP address []:
                         --->
```
2. When prompted, enter the IPv4 address subnet mask for the front-end network.
```
Enter the front-end IPv4 netmask [255.255.255.0]:
                               --->
```
3. When prompted, enter the IPv4 gateway IP address for the front-end network.
```
Enter the front-end IPv4 gateway IP address [172.20.43.254]:
                         --->
```
  If you entered IPv4 in response to the prompt in Step 6, you are finished entering front-end network configuration information for the node. Skip the next step in this procedure, and go to step 11.
  
  If you entered IPv6 or Dual, proceed to step 10.
If you entered IPv6 or Dual in response to the prompt in Step 6, specify the primary IPv6 node IP address, prefix length, and gateway IP address for the front-end network:
1. When prompted, enter the primary IPv6 address assigned to the HCP VM node for the front-end network.
  
  Important: Do not enter the front-end IP address for the KVM host. Enter the front-end network address for the HCP VM node.
```
Enter the front-end IPv6 IP address []:
                         --->
```
2. When prompted, enter the IPv6 address prefix length for the front-end network.
```
Enter the front-end IPv4 prefix length [64]:
                               --->
```
3. When prompted, enter the IPv4 gateway IP address for the front-end network.
```
Enter the front-end IPv4 gateway IP address [172.20.43.254]:
                         --->
```
4. When prompted, enter y to assign a secondary IPv6 address to the node for the front-end network, or n if you don’t want to assign a secondary IPv6 address to the node for the front-end network.
  Do you want to provide a second IP for the front-end IPv6 network? [n]:
5. If you entered y in response to the prompt in substep d, specify the secondary IPv6 node IP address, prefix length, and gateway IP address for the front-end network.
When prompted, enter the back-end network IP address for the HCP VM node.

Important: Do not enter the back-end IP address for the KVM host. Enter the back-end IP address for the HCP VM node.
```
Enter the back-end IPv4 IP address []:
                         --->
```
The installation program displays your responses to all of the previous prompts and asks you to confirm them.
In response to the confirming prompt, enter y to confirm your responses or n to change any responses.
In this case, the installation program repeats the prompts, starting again with the front-end network bonding mode.

At this point, the installation program runs a precheck to see if LUNs 0 or 128 exist. If the precheck finds these LUNs, the install fails. You must remove the LUNs before proceeding.

The installation program reformats the system volume and installs the OS. This process takes several minutes. While installing the OS, the installer should report its progress to the console.

If the OS installation is not proceeding as expected, you can press Alt+F2 to display a command prompt. This enables you to enter commands that can help you diagnose the problem. Pressing Alt+F2 to display a command prompt works only during OS installation. To return to the OS installation display, press Alt+F1.

When the installation is complete, the HCP VM node shuts down. If it does not restart, power on the HCP VM node using Virtual Machine Manager.

After the HCP VM node restarts, you are asked to change the password for the install user.
