Converting Nodes That Contain The Edirectory Master Replica; Failing Over Service Cluster Resources On Mixed-Node Clusters; Failing Over Data Cluster Resources On Mixed-Node Clusters; Managing File Systems In Mixed-Node Clusters - Novell OPEN ENTERPRISE SERVER - CONVERSION GUIDE 12-2010 Manual

If new cluster node IP addresses are required and new server hardware is being used, another option
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 5 of Section 4.1, "Converting NetWare Cluster Nodes to OES 2 Linux (Rolling
Cluster Conversion)," on page 27.
IMPORTANT: Failure to follow these recommendations might result in NetWare server abends
and Linux server restarts.
1.8 Converting Nodes that Contain the
eDirectory Master Replica
When converting NetWare cluster servers to Linux, do not convert the server that has the master
eDirectory replica first. If the server with the eDirectory master replica is a cluster node, convert it at
the end of the rolling cluster conversion.
1.9 Failing Over Service Cluster Resources on
Mixed-Node Clusters
For service cluster resources, the intention is to have a one-time cluster migration of the service
from NetWare to OES 2 Linux. After you cluster migrate the resource to an OES 2 Linux node, the
relocated resource should be cluster migrated only between nodes running the OES 2 Linux
platform.
1.10 Failing Over Data Cluster Resources on
Mixed-Node Clusters
Pool cluster resources that were created on NetWare cluster nodes and migrated or failed over to
Linux cluster nodes can be migrated or failed back to NetWare cluster nodes.
Cluster resources that were created on Linux cluster nodes cannot be migrated or failed over to
NetWare cluster nodes.
If you cluster migrate an NSS pool from a NetWare cluster server to a Linux cluster server, it could
take several minutes for volume trustee assignments to synchronize after the migration. Users might
have limited access to the migrated volumes until after the synchronization process is complete.
1.11 Managing File Systems in Mixed-Node
Clusters
In a mixed cluster of NetWare and OES 2 Linux nodes, Linux POSIX file systems as cluster
resources cannot be created until the entire cluster had been successfully converted to OES 2 Linux.
Linux POSIX file systems as cluster resources cannot be migrated or failed over to NetWare cluster
nodes.
Only NSS pool cluster resources that are created on a NetWare cluster node can be failed over
between Linux and NetWare nodes of a mixed-node cluster.
