How to determine the ESX network that NetBackup used for the backup or restore

If a virtual machine's disks are accessible to multiple ESX hosts, the disks can be accessed through any of the ESX hosts. The ESX host that is used for the access may or may not be the ESX host where the virtual machine is running or registered. All of the following must be accessible to each other and should have DNS configured:

If all hosts are not accessible to each other, the backup or restore may not succeed. In that case, you must determine which network NetBackup used for the backup or restore.

Note: For an NBD transport mode backup through vCenter, NetBackup uses the ESX network over which the ESX host was added or registered to the vCenter. For an NBD transport mode backup directly from the ESX host, NetBackup uses the ESX host's DNS/IP network.

The VxMS provider logs contain information on the network that NetBackup used.

See Configuring VxMS logging .

Check the VxMS provider logs for messages similar to those in this example:

VMware logs the messages starting with g_vixInterfaceLogger. Such messages in the example indicate that TestVM-000001.vmdk is opened over the ESX host network MyESX.xxx.xxx.com.
