Creating NCP volumes on a Linux LVM volume group clustered resource allows your NCP users to access the data by using NCP clients. NCP volumes can be used in a cluster environment with some modifications to the load, unload, and monitor scripts for the Linux LVM volume group cluster resource.
Make sure your system satisfies the Requirements for Creating LVM Cluster Resources
in the OES 2018 SP2: OES Cluster Services for Linux Administration Guide. The additional prerequisites in this section apply for NCP volumes:
NCP Server for Linux runs only on OES servers. For information about installing and configuring OES 2018 SP2, see the OES 2018 SP2: Installation Guide
.
NCP Server for Linux supports OES Cluster Services for OES servers. For information, see Installing, Configuring, and Repairing OES Cluster Services
in the OES 2018 SP2: OES Cluster Services for Linux Administration Guide.
The NCP Server and Dynamic Storage Technology (DST) software is not cluster aware. This OES install option must be selected and installed on every OES node in the cluster where you want to fail over shared NCP volumes.
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 2018 SP2: OES Cluster Services for Linux Administration Guide.
You need an unpartitioned disk or LUN that is connected via Fibre Channel or iSCSI protocols to the OES server.
The disk or LUN must be able to be managed by LVM.
OES Cluster Services for Linux requires that shared devices be managed by LVM and uses an LVM volume group that is activated exclusively on one node at a time. For information, see Requirements for Creating LVM Cluster Resources
in the OES 2018 SP2: OES Cluster Services for Linux Administration Guide.
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 LVM Cluster Resources
in the OES 2018 SP2: OES Cluster Services for Linux Administration Guide.
The Clustering plug-in to iManager is used to configure cluster resources, load scripts, and unload scripts for the Linux LVM volume group 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 OES Remote Manager for Linux is used to configure the NCP volume (or share) on the LVM logical volume on a clustered LVM volume group.
