Configure Additional Networks (CLI, v1.2.2 or earlier)

Language:

Use this procedure for MiniCluster systems running v1.2.2 or earlier. To determine your version, see List the MCMU Version (CLI).

Use one of these network interfaces to connect to the client access network:

Through the 10GbE NIC, using the first two ends of the four-ended splitter cable
Through the NET 2 and NET 3 ports

You can now configure additional networks on unused network interface slots for existing VMs, either in the same subnet or on a different subnet.

Determine which network interface slots are unused and are therefore available for you to configure as an additional network.
The network interface slots that are available for you to configure as an additional network depends on how your MiniCluster is connected to the client access network:
- If your MiniCluster is connected through the 10GbE NIC, through a QSFP to 4x SFP+ or MPO to 4x LC duplex splitter cable – You have the first two ends of the splitter cable (labeled A and B, or 1 and 2) connected to the client access network through 10GbE switches. The following network interface slots are therefore available on both compute nodes for you to configure as additional networks:
  - The other two ends of the splitter cable (labeled C and D, or 3 and 4) connected to the 10GbE NIC
  - The NET 2 and NET 3 ports
- If your MiniCluster is connected through the NET 2 and NET 3 ports – You are using those two ports on both compute nodes to connect to the client access network through 10GbE switches. The P 0 port (rightmost port, or port A) on the 10GbE NIC is therefore available for you to configure as additional networks. You can connect a QSFP to 4x SFP and SFP++ or an MPO to 4x LC duplex splitter cable to the P 0 port on the 10GbE NIC, which enables you to connect the four ends of the splitter cable (labeled A through D, or 1 through 4) to the additional network.
Refer to the Oracle MiniCluster S7-2 Installation Guide for more information on the connection options for the client access network.
Make the physical connections to the additional network, depending on which network interface slots are available to configure as an additional network.
Make one of the following pairs of connections to the additional network to provide high availability:
- From the 10GbE NIC:
  - The first two ends of the splitter cable (A and B, or 1 and 2), if not already used to connect to the client network
  - The second two ends of the splitter cable (C and D, or 3 and 4)
- From the NET 2 and NET 3 ports, if not already used to connect to the client network
Log into the MCMU CLI as a primary admin, such as mcinstall.
See Log in to the MCMU CLI.

Determine the VMgroupID of the VM group for the new network.

Perform one of these commands:

For DB VM groups, type:

In this example, the VMgroupID is 1.

% mcmu tenant -G -l
Listing DB VM Group...

Status : Active
Description :
VMgroupName : dbzg2
editable : True
deletable : True
progress : False
VMgroupID : 1

For App VM groups, type:

In this example, the VMgroupID is 2.

% mcmu tenant -A -l
Listing APP VM Group...

Status : Active
EditStatus :
Description : Drama App VM Group
  - shared
  - multiple
  - CIS
deletable : True
progress : False
VMgroupName : avm1
editable : True
VMgroupID : 2

Enter this CLI command to begin the configuration process for the additional network.
```
% mcmu network -a tenant
```

Select the VM group where you want to configure an additional network.

Specify the VMgroupID number.

Select ID [1] (1): 1

The VMs available in that VM group are listed:

ID | NAME                | GLOBALZONE | HOSTNAME
---+---------------------+------------+-----------------------
 1 | mc1dbzg1-vm1-mc1-n1 | mc1-n1     | mc1dbzg1-zone-1-mc1-n1
 2 | mc1dbzg1-vm1-mc1-n2 | mc1-n2     | mc1dbzg1-zone-1-mc1-n2

Select the VMs where you want to configure an additional network.

Enter comma separated list of VM ID(s) ID [1,2] : 1,2

The available (unused) network interface pairs are listed:

Select any of the interface pairs to configure a network
ID: 1
Interfaces: net4,net5

ID: 2
Interfaces: net6,net7

Select the network interface pairs that you want to use for the additional network.
```
Select ID [1/2] (1):
```
These are the network interface pairs that you can choose from:
- From the NET 2 and NET 3 ports – net2,net3
- From the 10GbE NIC:
  - The first two ends of the splitter cable (A and B, or 1 and 2) – net4,net5
  - The second two ends of the splitter cable (C and D, or 3 and 4) – net6,net7

Enter the remaining necessary information for the additional network.

Enter IP addresses for virtual_machine: 
Enter Netmask in CIDR form (valid range: 8-28): 
Do you want to input Gateway(Router) address?
Enter Y/N (N): 
Enter Default Gateway Address:
Do you want to input DNS Servers and Domain name values?
Enter Y/N (N):
VLAN ID is optional. Do you want to input this value?
Enter Y/N (N):
Enter CAN HA type (IPMP/AGGR):

A series of messages appear after you enter all the remaining necessary information for the additional network, providing information on the additional network that is being configured. The following message appears at the conclusion, which confirms that the additional network was configured successfully.

[INFO    ] Network successfully configured on all the VM(s)

Configure a second additional network, if necessary.
At this point, you used one of the unused network interface pairs to configure an additional network. Repeat these instructions to configure a second additional network using the remaining unused interface pair, if necessary.
