DHCP Server

1 1
The Novell DHCP Server for Linux is based on a standards-compliant implementation from ISC
that is distributed with SUSE Linux Enterprise Server. DHCP uses a different schema on Linux to
store the configuration in eDirectory.
After you set up Novell DHCP Server on the OES 2 Linux server and before you complete the
cluster conversion, you can use the DHCP option for the Migration Tool to convert the configuration
from NetWare to OES 2 Linux. You cannot directly reuse the data. Migrate your DHCP server data,
then perform the post-migration tasks to set up the configuration in the OES 2 Linux nodes of the
cluster.

11.1 Setting Up Novell DHCP on OES 2 Linux

Novell DHCP Server for OES 2 Linux supports using a shared Linux POSIX file system or a shared
NSS file system for the cluster resource. Set up DHCP on the OES 2 Linux servers by using one of
the following methods in the

11.3 Migrating the DHCP Configuration from
NetWare to Linux Clusters in the Same Tree
In this scenario, both the NetWare server and the OES 2 Linux server are in the same eDirectory
tree. The NetWare source server must be running NetWare 5.1 SP8 or later versions. The Linux
target server must be running OES 2 SP1 (or later) Linux on either 32-bit or 64-bit hardware.
Run the DHCP function in the Migration Tool from one of the OES 2 Linux nodes. Perform the Tree
Level Migration with the same Source server (tree to which NetWare clustered nodes are attached)
and Target server (tree to which the Linux clustered nodes are attached). This ensures that the entire
NetWare DHCP configuration data is available for OES 2 Linux DHCP.
For information, see "Migrating DHCP
and follow the instructions for NetWare and Linux in the same eDirectory tree.
