3.5.4 Starting and Stopping Novell Cluster Services
Novell Cluster Services automatically starts after it is installed. Novell Cluster Services also
automatically starts when you reboot your OES Linux server. If you need to manually start Novell
Cluster Services, go to the
/etc/init.d
directory and run
./novell-ncs start
. You must
be logged in as root to run
novell-ncs start
.
IMPORTANT: If you are using iSCSI for shared disk system access, ensure you have configured
iSCSI intiators and targets to start prior to starting Novell Cluster Services. You can do this by
entering
chkconfig iscsi on
at the Linux server console.
To have Novell Cluster Services not start automatically after rebooting your OES Linux server, enter
chkconfig novell-ncs off
at the Linux server console before rebooting the server. You can
also enter
chkconfig novell-ncs on
to again cause Novell Cluster Services to automatically
start.
3.6 Converting a NetWare Cluster to Linux
This section covers the following information to help you convert and manage a mixed NetWare 6.5
and Linux cluster.

Conversion),” on page 21
Š Section 3.6.2, “Adding New Linux Nodes to Your NetWare Cluster,” on page 23

Section 3.6.3, “Mixed NetWare and Linux Clusters,” on page 24
Š Section 3.6.4, “Finalizing the Cluster Conversion,” on page 26
If you have a NetWare 5.1 cluster, you must upgrade to a NetWare 6.5 cluster before adding new
Linux cluster nodes or converting existing NetWare cluster nodes to Linux cluster nodes.
See “ Upgrading Novell Cluster Services ” in the Novell Cluster Services Administration Guide for
information on upgrading Novell Cluster Services.
IMPORTANT: 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.
3.6.1 Changing Existing NetWare Cluster Nodes to Linux
(Rolling Cluster Conversion)
Performing a rolling cluster conversion from NetWare 6.5 to Linux lets you keep your cluster up and
running and lets your users continue to access cluster resources while the conversion is being
performed.
During a rolling cluster conversion, one server is converted to Linux while the other servers in the
cluster continue running NetWare 6.5. Then, if desired, another server can be converted to Linux,
