6.1.1 Supported Mixed-Node Clusters

Mixed NetWare and OES 2 Linux nodes in the same cluster are supported as a temporary
configuration while you are migrating a cluster from NetWare to Linux.
All NetWare servers must be either version 6.5 or 6.0 in order to exist in a mixed NetWare and OES
2 Linux cluster.
Mixed NetWare 6.5 and OES 2 Linux clusters are supported so that you can convert a NetWare
6.5 cluster to OES 2 Linux.
Mixed NetWare 6.0 and OES 2 Linux clusters are also supported so that you can convert a
NetWare 6.0 cluster to OES 2 Linux.
Mixed clusters consisting of NetWare 6.0 servers, NetWare 6.5 servers, and OES 2 Linux
servers are not supported.
Before converting NetWare 6.5 clusters or NetWare 6.0 clusters to OES 2 Linux, you must apply all
of the latest service packs and patches for that version. For information, see
Clusters" in the
If you have a NetWare 5.1 cluster, you must upgrade all nodes to a NetWare 6.5 cluster (with the
latest service packs and patches) before adding new Linux cluster nodes to the cluster. For
information, see
Administration

6.1.2 SBD Devices Must Be Marked as Shareable for Clustering

Novell Cluster Services for Linux requires that the devices used for the SBD partition be explicitly
marked as Shareable for Clustering. When converting a NetWare cluster, make sure that the SBD
device, or both devices for a mirrored SBD, are marked as Shareable for Clustering before you add
the first Linux node to the cluster.

6.1.3 Syntax Translation Issues for Load and Unload Scripts

When cluster migrating resources in a mixed-platform cluster from a NetWare cluster node to a OES
2 Linux cluster node, each cluster resource's Load script and Unload script needs to be translated in-
memory while the cluster contains mixed-platform nodes, and when the cluster is finally converted
from NetWare to Linux. Executing a script that is valid for the NetWare platform is not necessarily
recognized on the OES 2 Linux platform. This translation is done by the Cluster Translation Library
script (
/opt/novell/ncs/bin/clstrlib.py
unload scripts are not part of the normal translation library, the cluster resource can end up in a
comatose state.
