Configuring preferred addressing before creating a Virtual Client
When creating a virtual client it is advisable to configure preferred addressing on each node before creating the virtual client. The reason for this is that most clustered or DAG configurations have multiple IPaddesses configured for internode cluster communication or for access to a different subnet. To make sure these addresses do not effect NetVault backup’s virtual client configuration and communication with the NetVault server follow instructions below.
1/ on NetVault server edit the NetVault/etc/machines.dat file which contains all known clients and there IPaddesses. Locate the nodes in the cluster. Each node will have entry similar to the entry shown below. As we can see there are 4 network addresses seen against this node and NetVault has selected “10.11.6.115” as the Preferred Address and Contact Address which in this case are correct but this is not always the case and can this can change if we do don’t configure the correct Preferred Address on the client.
Note in this example the cluster IPaddress is 10.11.6.20
[DAG1]
Type=winnt
MachineID=3-Z53M-3DA
Release=NVBU 11000
NVVersion=11000
NVBuildLevel=52
Networks=169.254.1.148,192.168.6.1,10.11.6.115,10.11.6.20
Preferred Address=10.11.6.115
Contact Address=10.11.6.115
2/ on the virtual client node open NetVault configurator, select network manager, then sub tab connections. In here we put the preferred network address.
For this example the address would be 10.11.6.115
3/ then we need to configure the comma separated list of barred addresses. In here we put all other IPaddesses listed in the machines.dat file EXCEPT the cluster IPaddress.
In this case this would be: 169.254.1.148,192.168.6.1
4/ NetVault will decide when it needs to use the cluster IPaddress when talking to any node in the virtual client so it does not need to be configured as preferred network address or barred addresses.
5/ restart the NetVault services on the client
6/ in the WebUI go to the manage clients > select the client> manage> check access
Then verify firewall test passes.
7/ repeat this process on all nodes in cluster or DAG and you will be ready to create your virtual client.
