and then another, until all servers in the cluster have been converted to Linux. You can also leave the
cluster as a mixed NetWare and Linux cluster.
NOTE:
The process for converting NetWare 6.0 cluster nodes to OES Linux cluster nodes is the
same as for converting NetWare 6.5 cluster nodes to OES Linux cluster nodes.
IMPORTANT:
Mixed NetWare 6.5 and OES Linux clusters are supported, and mixed NetWare 6.0
and OES Linux clusters are also supported. Mixed clusters consisting of NetWare 6.0 servers,
NetWare 6.5 servers, and OES Linux servers are not supported. All NetWare servers must be either
version 6.5 or 6.0 in order to exist in a mixed NetWare and OES Linux cluster.
When converting NetWare cluster servers to Linux, do not convert the server that has the master
eDirectory replica first. If the server with the master eDirectory replica is a cluster node, convert it at
the end of the rolling cluster conversion.
To perform a rolling cluster conversion from NetWare 6.5 to Linux:
1
On the NetWare server you want to convert to Linux, run NWConfig and remove eDirectory.
You can do this by selecting the option in NWConfig to remove eDirectory from the server.
2
Bring down the NetWare server you want to convert to Linux.
Any cluster resources that were running on the server should fail over to another server in the
cluster.
3
In eDirectory, remove (delete) the Cluster Node object, the Server object, and all corresponding
objects relating to the downed NetWare server.
Depending on your configuration, there could be up to 10 or more objects that relate to the
downed NetWare server.
4
Run DSRepair on another server in the eDirectory tree to fix any directory problems.
If DSRepair finds errors or problems, run it multiple times until no errors are returned.
5
Install SLES 9 and OES on the server, but do not install the Cluster Services component of
OES.
You can use the same server name and IP address that were used on the NetWare server. This is
suggested, but not required.
See the
OES Linux Installation Guide
for more information.
6
Set up and verify SAN connectivity for the Linux node.
Consult your SAN vendor documentation for SAN setup and connectivity instructions.
7
Install Cluster Services and add the 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.
8
Enter
sbdutil -f
at the Linux server console to verify that the node can see the cluster
(SBD) partition on the SAN.
sbdutil -f also tells you the device on the SAN where the SBD partition is located.
9
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.
