62 Novell Business Continuity Clustering 1.1 Administration Guide for LinuxDuring a BCC upgrade, Business Continuity Clustering 1.0 clusters are unable to communicate withBusiness Continuity Clustering 1.1 clusters. This condition exists temporarily until the upgrade hasbeen completed. If an actual disaster were to occur during the upgrade, a Business ContinuityClustering 1.0 cluster can be failed over to a Business Continuity Clustering 1.1 cluster.3.2 Upgrading Business Continuity Clusteringfrom 1.0 or 1.1 for NetWare to 1.1 for LinuxTo upgrade from Business Continuity Clustering 1.0 (NetWare only) to Business ContinuityClustering 1.1 for Linux, you must first upgrade all nodes in Business Continuity Clustering 1.0clusters to Business Continuity Clustering 1.1 for NetWare. To do this, follow the instructions inSection 3.1, “Upgrading Business Continuity Clustering from 1.0 to 1.1 for NetWare,” on page 59.IMPORTANT: All cluster nodes in every cluster in your BCC must be upgraded to BusinessContinuity Clustering 1.1 for NetWare before converting clusters to Novell Cluster Services forLinux.Before you begin converting the NetWare clusters to Linux, see Section 2.1, “Requirements,” onpage 17 for more information on what is required for Business Continuity Clustering 1.1 for Linux.After all nodes have been upgraded to Business Continuity Clustering 1.1 for NetWare, you canbegin to convert them to Linux. On one cluster, upgrade NetWare cluster nodes to Linux byfollowing the instructions in “Converting a NetWare Cluster to Linux” (http://www.novell.com/documentation/oes/cluster_admin_lx/data/bu1b1x8.html) in the OES Novell Cluster Services 1.8.2Administration Guide for Linux.Clusters containing NetWare and Linux servers are supported in a BCC only as a temporary meansto convert a cluster from NetWare to Linux. Part of the temporary conversion state includes arestriction that only one mixed cluster can exist in your BCC. For example, Cluster A can have bothNetWare and Linux nodes, but Cluster B cannot. All nodes in Cluster B must be either NetWare orLinux.You must re-create the BCC-specific Identity Manager drivers after converting to Linux. SeeSection 2.4.1, “Configuring Identity Manager Drivers for the Business Continuity Cluster,” onpage 34.Normally, when converting a NetWare cluster to Linux, you need to run the cluster convertcommand after the entire cluster has been converted to Linux. When converting a BCC to Linux, donot run the cluster convert command until all clusters in the BCC have been upgraded andconverted to Linux. See “Finalizing the Cluster Conversion” (http://www.novell.com/documentation/oes/cluster_admin_lx/data/bu1b1x8.html#buj98g9) in the Novell Cluster Services1.8.2 for Linux Administration Guide.The same restrictions that apply to migrating or failing over resources between nodes within a mixedcluster also apply to migrating or failing over resources between clusters in a mixed BCC. You canonly migrate or fail over NSS pool/volume resources between clusters in a mixed BCC.
