to OES 2 Linux
You can use a rolling cluster conversion to convert a Novell Cluster Services cluster from NetWare
6.5 SP8 to Novell Open Enterprise Server (OES) 2 SP3 Linux. This section describes how to prepare
for and perform the conversion, and how to manage the temporarily mixed cluster during the
conversion.

4.1 Converting NetWare Cluster Nodes to OES 2
Linux (Rolling Cluster Conversion)
Performing a rolling cluster conversion from NetWare 6.5 to OES 2 Linux lets you keep your cluster
up and running and lets your users continue to access cluster resources while the conversion is being
performed.
During a rolling cluster conversion, one server is converted to Linux while the other servers in the
cluster continue running NetWare 6.5. Then, if desired, another server can be converted to OES 2
Linux, and then another, until all servers in the cluster have been converted to Linux. You can also
leave the cluster as a mixed NetWare and Linux cluster.
IMPORTANT: Before you begin, make sure you system meets the requirements and caveats in

If you are converting from NetWare on physical servers to OES 2 Linux on virtual servers (guest
operating systems running on Xen virtual machines), you can use the same methods and processes
as those used on a physical server. No additional changes or special configuration is required. For
information, see "Mixed Physical and Virtual Node
Services 1.8.8 Administration Guide for
To perform a rolling cluster conversion from NetWare 6.5 to OES 2 Linux:
1 Before you add the first Linux node to the NetWare cluster, if the NetWare cluster uses an SBD,
make sure that the device (or devices) being used by the SBD are marked as Shareable for
Clustering.
You can use NSSMU or iManager to mark the SBD devices as shareable. It is not necessary to
bring the cluster down when changing the device attribute to Shareable for Clustering.
Using NSSMU:
1a Log in to the master node of the NetWare cluster as the administrator user.
1b Enter
at the server console prompt.
