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 operating system, 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. 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.
