6.4 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.
The process for converting NetWare 6.0 cluster nodes to OES 2 Linux cluster nodes is the same as
for converting NetWare 6.5 cluster nodes to OES 2 Linux cluster nodes.
IMPORTANT: Before you begin, make sure you system meets the following requirements and
caveats:
Section 3.1, "System Requirements for Novell Cluster Services," on page 27
Section 6.1, "Guidelines for Converting Clusters from NetWare to OES 2 Linux," on page 59
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
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
1c In the NSSMU main menu, select Devices.
1d In the Devices list, highlight the device that contains the SBD partition, then press F5 to
select it.
1e Press F6 to mark the device as Shareable for Clustering.
1f If the SBD partition is mirrored, repeat
as Shareable for Clustering.
1g Press Esc to exit NSSMU.
2 Make a note of the services that are installed on the server you are converting.
You might want to install the same components on the Linux node if they are available.
3 On the NetWare server that you want to convert to Linux, remove eDirectory.
