Page 15: Overview Of Novell Cluster Services
Novell Cluster Services allows you to manage a cluster from a single point of control and to adjust resources to meet changing workload requirements (thus, manually “load balance” the cluster).
Page 16: Product Features
Server consolidation Storage consolidation 1.3 Product Features Novell Cluster Services includes several important features to help you ensure and manage the availability of your network resources: Support for shared SCSI, iSCSI, or Fibre Channel storage subsystems. Shared disk fault tolerance can be obtained by implementing RAID on the shared disk subsystem.
Page 17 The benefits that Novell Cluster Services provides can be better understood through the following scenario. Suppose you have configured a three-server cluster, with a Web server installed on each of the three servers in the cluster. Each of the servers in the cluster hosts two Web sites. All the data, graphics, and Web page content for each Web site is stored on a shared disk system connected to each of the servers in the cluster.
Page 18: Shared Disk Scenarios
You configured Web Site A to move to Web Server 2 and Web Site B to move to Web Server 3. This way, the workload once handled by Web Server 1 is evenly distributed. When Web Server 1 failed, Novell Cluster Services software did the following: Detected a failure.

For information about installing plug-ins in iManager, see “Downloading and Installing Plug-in...
Page 31 Novell Cluster Services supports creating shared cluster resources by using Novell Storage Services file system on Linux. NSS is not a required component for Novell Cluster Services on Linux unless you want to create and cluster-enable NSS pools and volumes. You can also use NSS for the SBD partition.
Page 32 Novell Cluster Services supports using Novell AFP for Linux as an advertising protocol for cluster- enabled NSS pools and volumes on OES 2 SP1 Linux and later. Novell AFP is not required to be installed when you install Novell Cluster Services, but it must be installed and running when you create and cluster-enable the shared NSS pool in order for the AFP option to be available as an advertising protocol for the cluster resource.
Page 33 “Configuring Novell Cluster Services in a Xen Virtualization Environment,” on page 181. Novell Cluster Services is supported to run on a Xen host server where it can be used to cluster the virtual machine configuration files on Linux POSIX file systems. Only the Xen and XenLive templates are supported for use in the XEN host environment.
Page 34: Configuration Requirements
8.8 Administration Guide for more information. If you are creating a new cluster, the eDirectory context where the new Cluster object will reside must be an existing context. Specifying a new context during the Novell Cluster Services install configuration does not create a new context.

Page 36: Shared Disk System Requirements
Web Browser The browser that will be used to manage Novell Cluster Services must be set to a supported language. For information about supported languages, see the Novell iManager documentation (http://www.novell.com/documentation/imanager27/). The Cluster plug-in for iManager might not operate properly if the highest priority Language setting for your Web browser is set to a language other than one of the supported languages.
Page 37 Before installing Novell Cluster Services or creating a new SBD partition, you must initialize the partition, and mark its device as shareable for clustering. If you plan to mirror the SBD, you must also initialize the partition you want to use as the mirrored SBD, and mark its device as shareable for clustering.
Page 38: San Rules For Lun Masking
I/O errors occur. The default setting in DM-MP is to queue I/O if one or more HBA paths is lost. Novell Cluster Services does not migrate resources from a node set to the Queue mode because of data corruption issues that can be caused by double mounts if the HBA path is recovered before a reboot.
Page 39: Novell Cluster Services Licensing
Link Down Retry=5 3.2 Novell Cluster Services Licensing Novell Cluster Services supports up to 32 nodes in a single cluster. Novell Open Enterprise Server 2 customers receive a Novell Cluster Services entitlement that covers an unlimited number of two- node clusters. Customers who want to add nodes to any cluster can purchase a paper license for them for an additional fee.

8.8 Configuring the EVMS Remote Request Timeout Novell Cluster Services for Linux uses the EVMS Cluster Segment Manager for shared devices. When load and unload scripts run, EVMS mounts or dismounts shared devices. The default timeout for remote requests for EVMS is 12 seconds. If you have many shared devices to be mounted or dismounted and the timeout is exceeded, you might see EVMS locking errors and some cluster resources can go comatose.

Page 134: Shared Storage
In order to use NSS pools and volumes in cluster resources, NSS must be installed and running on each server in the cluster. You can use the Storage plug-in for Novell iManager or the server-based NSSMU (NSS Management Utility) tool to create and cluster-enable a shared NSS pool, and to create NSS volumes on those pools.
Page 135: Ip Address
Common Internet File System (CIFS) is the Windows networking protocol. The Novell CIFS for Linux service is available beginning in the OES 2 SP1 Linux release. Novell CIFS is required when you want to give clients access via CIFS to volumes on the shared NSS pool.
Page 136: Considerations For Working With Shared Nss Pools And Volumes In The Cluster
Apple Filing Protocol (AFP) is the Macintosh* networking protocol. The Novell AFP for Linux service is available beginning in the OES 2 SP1 Linux release. Novell AFP is required when you want to give Macintosh clients access via AFP to volumes on the shared NSS pool.
Page 137: Creating Nss Shared Disk Partitions And Pools
NSS supports Fibre Channel SAN and iSCSI SAN environments. External SCSI device arrays can also be configured for multiple server access. Before enabling sharing on shared storage, Novell Cluster Services must be installed and running on your servers.

NSSMU and enter the password. NSS uses the password to create a key. Instead of storing it in the server memory as it does for non-shared volumes, NSS asks Novell Cluster Services to store the key and to pass it to the other nodes. After all servers hold the key, the volume is available for access as long as any one of the servers is still participating actively in the cluster.

Page 151: Understanding Nss Mirroring
10.10.1 Understanding NSS Mirroring NSS mirroring is a checkpoint-based synchronous mirroring solution. Data blocks are written synchronously to multiple storage devices. It is an alternative to synchronous replication options that are provided by a SAN array. Hardware configuration and placement for NSS mirroring can vary depending on geography and fault tolerance requirements.
Page 152: Requirements For Nss Mirroring
Novell Cluster Services should be installed and running prior to creating and mirroring partitions on shared storage. When you create a Novell Cluster Services system that utilizes shared storage space (a Storage Area Network or SAN), it is important to remember that all servers attached to the shared device, whether in the cluster or not, have access to all of the volumes on the shared storage space unless you specifically prevent such access.
Page 153 All servers in the cluster are connected to a shared storage system One or more drive arrays are configured on the shared storage system At least 20 MB of free space on the shared storage system for a special cluster partition To ensure disaster recovery, the device you select to mirror should be in a different storage array.

100%. 10.10.4 Verifying the NSS Mirror Status in the Cluster After you have configured NSS mirroring with Novell Cluster Services, you should check to ensure that it is working properly in a cluster environment. 1 Ensure that the volumes on the cluster-enabled pool are mounted on an assigned server by entering at the terminal console.
Page 155: Changing The Volume Id
128. 10.12 Changing the Volume ID Novell Cluster Services supports NCP client access to cluster-enabled NSS volumes by using a unique volume ID to mount the volume in the cluster. The volume ID is used by an NCP client only for automatic reconnects to the volume after failover or migration of a cluster resource.

In this scenario, you have OES 2 Linux (Xen) installed and configured on each node (physical machine). You then create either a NetWare or a Linux virtual machine on each physical machine and install and configure Novell Cluster Services on each virtual machine. The combined virtual machines (cluster nodes) comprise one cluster.
Page 191: Virtual Cluster Nodes In Separate Clusters
You then create multiple NetWare or Linux virtual machines on each physical machine and install and configure Novell Cluster Services on each virtual machine. During the Novell Cluster Services installation, you create separate clusters of virtual cluster nodes, with each virtual cluster node residing on a separate physical machine.
Page 192 Shared Disk System Another method is to install Novell Cluster Services on physical NetWare nodes and create a separate cluster for each node. You then install an OES 2 Linux (Xen) server (physical machine) and create NetWare virtual machines and install Novell Cluster Services on each virtual machine. You can then add one virtual NetWare cluster node to each cluster to create multiple two-node clusters, each containing one physical and one virtual cluster node.
