and Unload Scripts
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.

3.1 Translation of Cluster Resource Scripts for
Mixed NetWare and Linux Clusters
Novell Cluster Services includes specialized script translation functionality, called the Cluster
Translation Library script (
servers coexist in the same cluster. It provides an automatic translation of the Master IP Address
resource and cluster-enabled NSS pool resource load and unload scripts from NetWare to Linux.
This functionality is also beneficial as you migrate NetWare cluster servers to Linux.
The Cluster Translation Library reads the NetWare load and unload scripts from eDirectory,
converts them, and writes them as Linux load and unload script files. The Linux load and unload
script files are then searched for NetWare-specific command strings, and the command strings are
then either deleted or replaced with Linux-specific command strings. Separate Linux-specific
commands are also added, and the order of certain lines in the scripts is also changed to function
with Linux.
The Linux load and unload scripts are stored in files on Linux cluster servers, instead of being stored
in eDirectory like the NetWare scripts. The cluster resource name is used in the load and unload
script filenames. The path to the files is
IMPORTANT: Use the Properties > Scripts page in the Clusters plug-in in iManager whenever
you make manual changes to the load and unload scripts. The changes are automatically saved to the
files.
