About setting up dynamic IP addresses and host names
Configure the network to use a dynamic IP addressing protocol. A protocol like DHCP has a server and several clients. For example, when a DHCP client starts up, it requests an IP address from the DHCP server. The server then assigns an IP address to the client from a range of predefined addresses.
NetBackup requires that the IP addresses of NetBackup clients have corresponding network host names. Ensure that each IP address that can be assigned to NetBackup clients has a network host name. The host name should be defined in the host file, NIS, and DNS on the network.
For example, ten dynamic IP addresses and host names are available.
The dynamic IP addresses and host names might be as follows:
123.123.123.70 dynamic00
123.123.123.71 dynamic01
123.123.123.72 dynamic02
123.123.123.73 dynamic03
.

.
123.123.123.79 dynamic09Assign a unique NetBackup client name to each NetBackup client that might use one of these dynamic IP addresses. The NetBackup client name that is assigned to a client is permanent and should not be changed. The client name that is assigned to NetBackup clients with dynamic IP addressing must not be the same as any network host names on the network. If the NetBackup client names are changed or are not unique, backup and restore results are unpredictable.
For example, 20 computers share the IP addresses as previously defined.
To make these computers NetBackup clients, assign them the following NetBackup client names:
nbclient01
nbclient02
nbclient03
nbclient04
