To convert a business continuity cluster from BCC 1.1 SP2 for NetWare to BCC 1.2 for Linux, you must convert all of the nodes in every peer cluster from NetWare 6.5 SP8 (OES 2 SP1 NetWare) to OES 2 SP1 Linux. Consider the following caveats as you convert the clusters to Linux:
Clusters containing both NetWare and Linux servers are supported in a BCC only as a temporary means to convert a cluster from NetWare to Linux.
Part of the temporary conversion state includes a restriction that only one mixed cluster can exist in your business continuity cluster at a time. For example, Cluster A can have both NetWare and Linux nodes, but Cluster B cannot. All nodes in Cluster B must be either NetWare or Linux.
The same restrictions that apply to migrating or failing over resources between nodes within a mixed cluster also apply to migrating or failing over resources between clusters in a mixed BCC. You can migrate or fail over only NSS pool/volume resources that were originally created on NetWare between the peer clusters in a mixed BCC.
On one cluster at a time, do the following:
Convert NetWare cluster nodes to Linux by following the instructions in Converting NetWare 6.5 Clusters to OES 2 Linux
in the OES 2 SP1: Novell Cluster Services 1.8.6 for Linux Administration Guide.
IMPORTANT:Do not perform the step to finalize the cluster conversion until after all of the nodes in every peer cluster in the business continuity cluster have been converted to Linux, and the BCC drivers for Identity Manager have been re-created.
Add a Read/Write replica of the cluster’s eDirectory™ partition to the new Linux nodes.
Stop the Identity Manager drivers, then remove the old NetWare Identity Manager node from the cluster.
Install Identity Manager 3.6x on one Linux node in each cluster.
IMPORTANT:Identity Manager 3.6 supports only a 32-bit OES 2 Linux operating system, even on 64-bit hardware. Identity Manager 3.6.1 supports the 64-bit OES 2 SP1 Linux operating system.
Configure the BCC Administrator user and group for the Linux cluster.
On Linux, the BCC Administrator user must be Linux-enabled with Linux User Management. The user must also be added to the Novell Cluster Services administration group (such as ncsgroup) on each cluster node. Follow the steps outlined in Section 4.3, Configuring a BCC Administrator User and Group to do the following:
Create the bccgroup and add the BCC Administrator to it.
LUM-enable the bccgroup and add all the Linux nodes in the cluster to it.
Assign trustee rights for the BCC Administrator user to the cluster objects.
Add the BCC Administrator user to the ncsgroup on each cluster node.
(Conditional) If you LUM-enabled the Linux/UNIX Workstation object for a server after BCC is running, restart BCC on that server before continuing to the next node in the cluster.
