[. . . ] The preview switch lets you view the resource load and unload script changes that will be made when the conversion is finalized. Replace resource_name with the name of a resource that you want to preview. Beginning in OES 2 SP3, you can preview the information for all cluster resources by issuing the command without specifying a resource name. 2 Run cluster convert commit at the terminal console of one Linux cluster node to finalize the conversion. 32 OES 2 SP3: Novell Cluster Services Conversion Guide The cluster convert commit command generates or regenerates the cluster resource templates that are included with Novell Cluster Services for Linux. In addition to generating Linux cluster resource templates, this command deletes all NetWare cluster resource templates that have the same name as Linux cluster resource templates. The cluster resource templates are automatically created when you create a new Linux cluster, but are not created when you convert an existing NetWare cluster to Linux. 3 Update the cluster configuration on all nodes by running the cluster configuration daemon. Enter the following command as the root user on every node in the cluster: /opt/novell/ncs/bin/ncs-configd. py -init This removes the NetWare nodes from the list of nodes in the cluster so they are not displayed in iManager. Converting NetWare 6. 5 Clusters to OES 2 Linux 33 34 OES 2 SP3: Novell Cluster Services Conversion Guide 5 Novell AFP 5 Novell Apple Filing Protocol (AFP) for Linux is available beginning in OES 2 SP1 Linux. After you set up Novell AFP on the Linux node and before you finalize the NetWare-to-Linux conversion, use the AFP function in the Migration Tool to convert the configuration. For information, see "Migrating AFP from NetWare to OES 2 SP3 Linux " in the OES 2 SP3: Migration Tool Administration Guide. After the migration, modify the load and unload scripts on the Linux server. For information, see Section 3. 6, "Comparing File Access Protocol Resource Script Commands, " on page 23. AFP on Linux supports NCP cross-protocol file locking, which allows NCP, AFP, and CIFS users to access files on an NSS volume concurrently without data corruption by locking the files across protocols. On Linux, the cross-protocol file locking parameter for NCP Server is disabled by default. It must be enabled on each node in the cluster if you plan to give both NCP users and AFP users access to NSS volume in the cluster. See "Configuring Cross-Protocol File Locks for NCP Server" in the OES 2 SP3: NCP Server for Linux Administration Guide. Novell AFP 35 36 OES 2 SP3: Novell Cluster Services Conversion Guide 6 Apache Web Server 6 This section describes how reuse the Apache Web Server cluster resource when you convert a cluster from NetWare 6. 5 SP8 to Novell Open Enterprise Server (OES) 2 for Linux. For information about installing and configuring Apache on OES 2 Linux, see "Section 40, Apache HTTP Server" (http://www. novell. com/documentation/sles10/book_sle_reference/data/ cha_apache2. html) in the SLES 10 SP3 Installation and Administration Guide (http:// www. novell. com/documentation/sles10/book_sle_reference/data/book_sle_reference. html). Section 6. 1, "Prerequisites, " on page 37 Section 6. 2, "Converting the Apache Cluster Resource, " on page 37 Section 6. 3, "Additional Information, " on page 40 6. 1 Prerequisites You must install Novell Storage Services on the OES 2 Linux servers in order to reuse the cluster resource that contains the Web site files. After you convert the cluster, you will install the Web and Lamp Server functional pattern and set up Apache services. 6. 2 Converting the Apache Cluster Resource 1 In iManager, offline the NSS pool cluster resource from a NetWare node, then modify its load and unload scripts to remove the Apache start and stop commands. 2 In iManager, online the cluster resource on a NetWare node to activate the changes you made to the scripts. 3 In iManager, cluster migrate the cluster resource to a Linux node, then offline the resource. 5 For each Linux node in the cluster, install the Web and LAMP Server option under the Linux Primary Functions category. The Web and LAMP Server pattern includes the Apache and MySQL packages, and scripting languages such as PHP, Python, Ruby on Rails, and Perl. [. . . ] Before you add the first Linux node to the NetWare cluster, mark the NetWare cluster SBD devices as Shareable for Clustering A. 4 January 20, 2010 Updates were made to the following section.
