Locating a client

The clients that reside in a different subnet are not included in the list of available clients. You can use the Find Machine option to locate and add such clients.

To locate and add a client that is not discovered automatically:
1
Start the client addition wizard, and then click Find Machine.
2
On the Find Client page, type the Fully Qualified Domain Name (FQDN) or IP address of the client, and click Find.
3
After the machine is located, complete Step 3 through Step 6 in the section Adding a client to the NetVault Backup Server.
 
* 
NOTE: NetVault Backup reports an error if it fails to locate the specified client on the network. An error can occur for reasons such as the following:
•
The NetVault Backup software is not installed on the machine.
•
The NetVault Backup Service is not running on the machine.
•
The DNS lookup table or the machine’s host table cannot be contacted.

Checking communication through a firewall

When adding a client that resides outside the firewall, you can perform a firewall test to check if the server and client can communicate through the firewall. You can also perform this test to check connectivity for existing clients.

To check if the server and client can communicate through a firewall:
1
To check connectivity for new clients, start the client addition wizard, and then click Firewall Test.
— or —
To check connectivity for existing clients, open the Manage Clients page. Select the client, and then click Firewall Test.
2
In the Check Connection dialog box, provide the following details.

Description

NetVault Client Name

For new clients, type the NetVault Backup name of the machine.

For existing clients, the name is displayed as a read-only property.

NetVault Client Address

For new clients, type the IP address of the machine.

For existing clients, the IP address is displayed as a read-only property.

UDP Port

The default UDP port for NetVault Backup. It is set to 20031. If you have configured NetVault Backup to use a different port, change this value.

TCP Port

The default UDP port for NetVault Backup. It is set to 20031. If you have configured NetVault Backup to use a different port, change this value.

Timeout

The timeout interval is set to 15 seconds by default.

3
Click Test. This command checks if TCP, UDP, and messaging connectivity is available between the server and client, and displays the result in the dialog box.
 
* 
IMPORTANT: The firewall test option checks the connectivity to the Stats Manager process on the specified server or client machine. If this process is not running on the client, the test fails. However, the client may still be accessible for backup. In any case, it is an abnormal situation and should be corrected.

Adding a server as a client

To allow a NetVault Backup Server to function as a client to a different server, you must enable the setting This machine may be added as a client to a server on the server.

To allow a NetVault Backup Server to function as a client to a different server:
1
In the Navigation pane, click Change Settings, and then on the Configuration page, click Server Settings.
2
Under System and Security, click Security. In the Security dialog box, configure the following setting:
•
This machine may be added as a client to a server: The security settings on a NetVault Backup Server prevent the server from being added as a client to a different server. To allow a NetVault Backup Server to function as a client to a different serve, select this check box.
3
Click Apply to apply the new settings and close the dialog box.

Removing a client from the list of available clients

If the list of available clients includes a machine that is no longer in use, you can use the following procedure to remove it from the list.

To remove a defunct client from the list of available clients:
1
Start the client addition wizard.
2
In the NetVault Backup Clients table, select the defunct client, and click Remove.
