You can add new OES 2 Linux cluster nodes to your existing NetWare 6.5 cluster without bringing down the cluster.
Before you add the first Linux node to the NetWare cluster, if the NetWare cluster uses an SBD, make sure that the device (or devices) being used by the SBD are marked as .
You can use NSSMU or iManager to mark the SBD devices as shareable. It is not necessary to bring the cluster down when changing the device attribute to .
Using NSSMU:
Log in to the master node of the NetWare cluster as the administrator user.
Enter nssmu at the server console prompt.
In the NSSMU main menu, select .
In the list, highlight the device that contains the SBD partition, then press F5 to select it.
Press F6 to mark the device as .
If the SBD partition is mirrored, repeat Step 1.d and Step 1.e to also mark the mirror device as .
Press Esc to exit NSSMU.
Install OES 2 Linux on the new node, but do not install the Novell Cluster Services option from OES Services at this time.
See the OES 2 SP2: Installation Guide
for more information.
Set up and verify SAN connectivity for the new OES 2 Linux node.
Consult your SAN vendor documentation for SAN setup and connectivity instructions.
Install Cluster Services and add the new node to your existing NetWare 6.5 cluster.
See Section 3.5.2, Installing Novell Cluster Services on an Existing OES 2 Linux Server for more information.
If you have a shared disk system on the cluster, enter sbdutil -f at the Linux terminal 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.
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.
Add and assign cluster resources to the new Linux cluster node.
For information, see Section 9.9, Assigning Nodes to a Resource.
