Removing Other Segment Managers If any of the shared disks you plan to use with your cluster have other segment managers, you must delete them as well. 1 In evmsgui, click the Disks tab, then right-click the disk you plan to use for a cluster resource. This option only appears if there is another segment manager for the selected disk. 3 Select the listed segment manager and click Remove. Installation and Setup 33 novdocx (ENU) 29 January 2007 Creating a Cluster Segment Manager Container To use a traditional Linux volume with EVMS as a cluster resource, you must use the Cluster Segment Manager (CSM) plug-in for EVMS to create a CSM container. NOTE: CSM containers require Novell Cluster Services (NCS) to be running on all nodes that access the CSM container. 3 Select the disks (storage objects) you want to place in the container, then click Next. 4 On the Configuration Options page, select the node where you are creating the container, specify Private as the type, then choose a name for the container. The name must be one word, must consist of standard alphanumeric characters, and must not be any of the following reserved words: Container Disk EVMS Plugin Region Segment Volume 5 Click Save to save your changes. Adding an Additional Segment Manager After creating a CSM container, you can optionally add an additional non-CSM segment manager container on top of the CSM container you just created. The benefit of this is that other non-CSM segment manager containers allow you to create multiple smaller EVMS volumes on your EVMS disk. You can then add additional EVMS volumes or expand or shrink existing EVMS volumes to utilize or create additional free space on your EVMS disk. In addition, this means that you can also have different file system types on your EVMS disk. A CSM container uses the entire EVMS disk, which means that creating additional volumes or expanding or shrinking volumes is not possible. And, because only one EVMS volume is possible in the container, only one file system type is allowed in that container. 1 In evmsgui, click Actions, select Add, then select Segment Manager to Storage Object. 3 Choose the storage object (container) you want to add the segment manager to, then click Next. 4 Select the disk type (Linux is the default), click Add, then click OK. 5 Click Save to save your changes. 34 OES Novell Cluster Services 1. 8. 2 Administration Guide for Linux novdocx (ENU) 29 January 2007 Creating an EVMS Volume 1 In evmsgui, click Actions, select Create, and then EVMS Volume. 2 Select the container you just created (either the CSM container or the additional segment manager container) and specify a volume name. Creating a File System on the EVMS Volume 1 In evmsgui, click the Volumes tab and right-click the volume you just created. [. . . ] If you don't enter a device name, you won't be able to cluster enable NSS Pools. 4. 6. 9 Creating a Cluster Partition (SBD Partition) after Installation If you did not create a cluster partition during the Novell Cluster Services installation, you can create one later using the SBDUTIL utility. You must have a shared disk system (a Storage Area Network or SAN) connected to your cluster nodes before attempting to create a cluster partition. See Section 3. 3, "Shared Disk System Requirements, " on page 18 for more information. Before creating an SBD partition, you should first make sure one does not already exist on your shared disk system. [. . . ]
