Business Continuity Clustering 2.6 Readme

May 2020

This Readme identifies known issues for Business Continuity Clustering (BCC) 2.6 for your Open Enterprise Server (OES) 2018 Support Pack 2 (SP2) servers that are running Novell Cluster Services (NCS).

1.0 Minimum System Requirements

Business Continuity Clustering supports up to four peer clusters that are running OES 2018 SP2 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.

Identity Manager 4.8

The credential to activate IDM is included in the BCC license.

2.0 Downloads

Beginning with OES 2018 SP2, 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 Open Enterprise Server 2018 SP2 through Micro Focus Downloads. Apply the latest OES 2018 SP2 maintenance patches on all nodes in every peer cluster. Patches are available through the OES 2018 SP2 patch channel.

In addition, you must download the following product:

  • Identity_Manager_4.8 for OES 2018 SP2

    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_4.8.0_HF1_Engine 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 Micro Focus Patch Finder.

    Use the following steps to install IDM 4.8.0.1 hot fix:

    1. rpm -Uvh --force novell-DXMLbasenoarch.rpm

    2. rpm -Uvh novell-DXMLeventx.rpm --nodeps

    3. Restart eDirectory

3.0 Known Issues

This section identifies known issues for BCC on OES 2018 SP2 clusters running NCS.

3.1 Incorrect Status in the Cluster View Report After Enabling BCC on Peer Clusters

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.

3.2 Cannot Add a New Volume on a BCC Migrated NSS Pool

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 BCC Administration Guide for OES 2018 SP2.

3.3 Multiple-Tree Configurations Are Not Supported

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.

3.4 Upgrade from NetWare to Linux Does Not Support Mixed Peer Clusters

BCC 2.6 does not support mixed peer clusters of NetWare and Linux. A cluster in mixed-mode that contains both NetWare and Linux servers is supported in a BCC peer cluster only as a temporary means to convert a cluster from NetWare to Linux. The cluster is considered a NetWare cluster, and only NetWare nodes are enabled for BCC. Resources running on Linux nodes in the mixed cluster cannot fail over to a peer cluster.

Before you begin the conversion of a BCC from NetWare to Linux, ensure that you understand the sequence of tasks and the limitations of working in mixed-mode in a BCC. For information, see Converting BCC Clusters from NetWare to Linux in the BCC Administration Guide for OES 2018 SP2.
