(Conditional) If necessary, manually migrate the resources that were on the former NetWare
server to this Linux server.
The resources will automatically fail back if all of the following apply:
The failback mode for the resources was set to Auto.
You used the same node number for this Linux server as was used for the former NetWare
server.
This only applies if this Linux server is the next server added to the cluster.
This Linux server is the preferred node for the resources.
Simultaneously Changing Multiple NetWare Cluster Nodes to Linux
If you attempt to simultaneously convert multiple NetWare cluster servers to 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 3 on page 22
.
Failure to follow these recommendations might result in NetWare server abends and Linux server
restarts.
3.6.2 Adding New Linux Nodes to Your NetWare Cluster
You can add new Linux cluster nodes to your existing NetWare 6.5 cluster without bringing down
the cluster. To add new Linux cluster nodes to your NetWare 6.5 cluster:
1
Install SLES 9 and OES on the new node, but do not install the Cluster Services component of
OES.
See the “
OES Linux Installation Guide
” for more information.
2
Set up and verify SAN connectivity for the new Linux node.
Consult your SAN vendor documentation for SAN setup and connectivity instructions.
3
Install Cluster Services and add the new node to your existing NetWare 6.5 cluster.
See
Section 3.5.3, “Installing Novell Cluster Services after the OES Installation,” on page 20
for more information.
4
Enter
sbdutil -f
at the Linux server console to verify that the node can see the cluster
(SBD) partition on the SAN.
sbdutil -f
will also tell you the device on the SAN where the SBD partition is located.
5
Start cluster software by going to the
/etc/init.d
directory and running
novell-ncs
start
.
You must be logged in as root to run
novell-ncs start
.
6
Add and assign cluster resources to the new Linux cluster node.
