This Readme identifies known issues for Business Continuity Clustering (BCC) 2.6 for your Open Enterprise Server (OES) 23.4 servers that are running Novell Cluster Services (NCS).
Business Continuity Clustering supports up to four peer clusters that are running OES 23.4 and Novell Cluster Services.
The BCC operating environment requires the versions of OES and NetIQ products listed in Table 1, with the latest patches applied.

Beginning with OES 2018 SP1, Novell Business Continuity Cluster (BCC) is available as a pattern in the OES installation pattern list. However, BCC continues to be a separate product with its own license.
Download the OES 23.4 through Downloads.
In addition, you must download the following product:
Identity_Manager_4.8 for OES 23.4
The credential that you need to use Identity Manager drivers beyond the evaluation period is found in the BCC license.
You must apply all maintenance patches for Identity_Manager_4.8.7 on the Identity Manager node in each of the peer clusters before you install or upgrade BCC on any of the nodes in any peer cluster. Patches are available on OpenText Patch Finder.
This section identifies known issues for BCC on OES 23.4 clusters running NCS.
BCC enabled cluster resource migration fails between the BCC peer clusters. The resource goes to unassigned state after migration. To troubleshoot this issue, before initiating the migration process, perform nlvm rescan on all the nodes of the target cluster, where the BCC cluster resource has to be up and running.
In OES 2023 with BCC installed and configured, enabling only the TLS v1.3 protocol in the sfcb.cfg file makes the BCC cluster connections to break. To avoid this and maintain stable connections, enable TLS v1.2 as well.
After the set up of BCC and enabling it on peer clusters, the cluster view report on one of the node in the first cluster shows only one peer cluster as configured instead of showing all the peer clusters. However, the cluster view report on all the other nodes correctly shows all the peer clusters configured. To view the correct cluster view report on the node in first cluster where the issue is seen, execute the command cluster refresh -p.
When a BCC-enabled pool cluster resource is brought online in a peer cluster other than where it was originally created, you cannot add a new volume on the pool. The volume is created on the disk, but the Volume object fails to be added to Novell eDirectory with Error 613: Error adding volume to NDS.
We recommend that you create only one volume per pool cluster resource. If you need to add a volume on a BCC-enabled pool cluster resource, you must BCC-migrate the resource back to the peer cluster where the pool was originally created.
In some disaster situations, it is possible that the pool cluster resource has been permanently relocated to the current peer cluster. To cluster-enable the pool in its current cluster, see Permanently Relocating a Cluster Resource to a Peer Cluster in the OES 23.4: BCC Administration Guide.
In the BCC 2.6 release, multiple-tree configurations of business continuity clusters are not supported. All peer clusters must reside in the same tree.
