Creating NCP volumes on clustered Linux POSIX file systems allows your NCP users to access the data using NCP clients. NCP volumes can be used in a cluster environment with some modifications to the load and unload scripts for the Linux POSIX cluster resource.
Make sure your system satisfies the Requirements for Creating Linux POSIX Volume Cluster Resources
in the OES 2 SP3: Novell Cluster Services 1.8.8 Administration Guide for Linux. The additional prerequisites in this section apply for NCP volumes:
NCP Server for Linux runs only on OES 2 Linux servers. For information about installing and configuring OES 2 Linux, see the OES 2 SP3: Installation Guide
.
NCP Server for Linux supports Novell Cluster Services for OES 2 Linux or later servers. For information, see Installing and Configuring Novell Cluster Services on OES 2 Linux
in the OES 2 SP3: Novell Cluster Services 1.8.8 Administration Guide for Linux.
The NCP Server and Dynamic Storage Technology (DST) software are not cluster aware. This OES install option must be selected and installed on every OES 2 Linux node in the cluster where you want to fail over shared NCP volumes. You do not cluster NCP Server services or DST services.
For install information, see Section 3.0, Installing and Configuring NCP Server for Linux.
The NCP volume must reside on a shareable device. For more information, see Shared Disk Configuration Requirements
and SAN Rules for LUN Masking
in the OES 2 SP3: Novell Cluster Services 1.8.8 Administration Guide for Linux.
You need an unpartitioned disk or LUN that is connected via Fibre Channel or iSCSI protocols to the OES 2 Linux server.
The disk or LUN must be able to be managed by EVMS.
Novell Cluster Services for Linux requires that shared devices be managed by EVMS (Enterprise Volume Management System) and have a Cluster Segment Manager on the device. For information, see Requirements for Creating Linux POSIX Volume Cluster Resources
in the OES 2 SP3: Novell Cluster Services 1.8.8 Administration Guide for Linux.
In a cluster environment, NCP Server supports NCP volumes on Linux POSIX file systems, including Ext3, XFS, and ReiserFS. For information about requirements and caveats, see Requirements for Creating Linux POSIX Volume Cluster Resources
in the OES 2 SP3: Novell Cluster Services 1.8.8 Administration Guide for Linux.
To create or modify home directories on clustered NCP volumes or to manage any other elements that are managed using eDirectory objects, you must cluster migrate the cluster resource back to the node where the NCP volume was created before you perform those management tasks.
The Clustering plug-in to iManager 2.7 is used to configure cluster resources, load scripts, and unload scripts for the Linux POSIX volume’s clustered resource. The Directory Administration plug-in is used to create the virtual cluster server object for the NCP volume.
The NCP Server plug-in to Novell Remote Manager for Linux is used to configure the NCP volume (or share) on a clustered Linux POSIX file system.
