Installation and Setup 45The script is located in the /nsmi_scripts/linux/ directory on the Business ContinuityClustering 1.1 CD or ISO image.11 Click Apply to save your changes.12 Repeat Step 1 through Step 11 for the peer clusters in your BCC.The information you provide in the steps should be unique for each cluster.Verifying BCC Administrator User Trustee Rights and CredentialsYou must ensure that the BCC Administrator user is a LUM-enabled user. For instructions, see“Creating the BCC Group and Administrative User” on page 23.You must ensure that the user who manages your BCC (that is, the BCC Administrator user) is atrustee of the Cluster objects and has at least Read and Write rights to the All Attributes Rightsproperty. For instructions, see “Assigning Trustee Rights for the BCC Administrator User to theCluster Objects” on page 24.In order for the BCC Administrator user to gain access to the cluster administration files (/admin/novell/cluster) on other Linux cluster nodes in your BCC, you must add that user to thencsgroup on each cluster node. For instructions, see “Adding the BCC Administrator User to thencsgroup on Each Cluster Node” on page 24.2.4.3 Configuring Cluster Resources for Business ContinuityCluster resources can be configured for business continuity after they are created. Configuring aresource for business continuity consists of enabling that resource for business continuity, addingload and unload scripts’ search and replace data specific to the resource, and selecting peer clustersfor the resource.IMPORTANT: In a business continuity cluster, you should have only one NSS pool for each LUNthat could be failed over to another cluster. This is necessary because in a business continuity cluster,entire LUNs fail over to other clusters, rather than individual pools, which fail over to other nodeswithin a cluster.A cluster-enabled NSS pool must contain at least one volume before its cluster resource can beenabled for business continuity. You get an error message if you attempt to enable the resource forbusiness continuity if its NSS pool does not contain a volume.Also, if you have encrypted NSS volumes in your BCC, then all clusters in that BCC must be in thesame eDirectory tree. If not, then the clusters in the other eDirectory tree cannot decrypt the NSSvolumes. This rule applies to both NetWare and Linux BCCs. “Enabling a Cluster Resource for Business Continuity” on page 46 “Adding Resource Script Search and Replace Values” on page 46 “Selecting Peer Clusters for the Resource” on page 48 “Adding SAN Array Mapping Information” on page 48
