Beginning in OES 2 SP2, Novell Cluster Services allows you to customize the translation syntax
that is used for load and unload scripts in mixed-platform situations by defining them in the
/var/
opt/novell/ncs/customized_translation_syntax
file that you create. The
clstrlib.py
script reads the additional translation syntax from the syntax file. For information, see
Section 6.7,
“Customizing the Translation Syntax for Converting Load and Unload Scripts,” on page 87
.
6.1.4 Case Sensitivity Issues
When adding a Linux node to the existing NetWare cluster, there are two areas where case
sensitivity might be an issue:
Node name:
After you install the Linux node into the NetWare cluster, the Linux node is
unable to join the cluster. To resolve this problem, edit the
/etc/opt/novell/ncs/nodename
file to modify the hostname of the node from lowercase (
clusnode1
) to all uppercase
characters (CLUSNODE1), reboot the server, then run the
rcnovell-ncs start
command.
This allows the cluster node to start and join the cluster.
NOTE:
This case sensitivity issue has been resolved for OES 2 SP2 and later.
Cluster object name:
The Cluster object name (such as
cn=Clustername,ou=context,o=org
) is also present on the SBD partition. The SBD name
(
Clustername.sbd
) matches the case of the object name in eDirectory
TM
. Running the
sbdutil -f
command displays the SBD name. If the case used when you enter the Cluster
object name and SBD name during the Linux cluster install do not match the case used in
eDirectory, the cluster install fails to detect the SBD partition.
6.1.5 Adding New NetWare Nodes to a Mixed-Node Cluster
You cannot add additional NetWare nodes to your cluster after adding a new Linux node or changing
an existing NetWare cluster node to a Linux cluster node. If you want to add NetWare cluster nodes
after converting part of your cluster to Linux, you must first remove the Linux nodes from the
cluster.
6.1.6 Converting Multiple NetWare Cluster Nodes to OES 2
Linux
If you attempt to concurrently convert multiple NetWare cluster servers to OES 2 Linux, we strongly
recommend that you use the old NetWare node IP addresses for your Linux cluster servers. You
should record the NetWare node IP addresses before converting them to Linux.
If you must assign new node IP addresses, we recommend that you only convert one node at a time.
Another option if new cluster node IP addresses are required and new server hardware is being used
is to shut down the NetWare nodes that are to be removed and then add the new Linux cluster nodes.
After adding the new Linux cluster nodes, you can remove the NetWare cluster node-related objects
as described in
Step 5
of
Section 6.4, “Converting NetWare Cluster Nodes to OES 2 Linux (Rolling
Cluster Conversion),” on page 78
.
IMPORTANT:
Failure to follow these recommendations might result in NetWare server abends
and Linux server restarts.
