PRIMECLUSTER Wizard for NAS 4.3 Configuration and Administration Guide

1.1 Feature outline

PRIMECLUSTER Wizard for NAS is a software product that facilitates cluster operation management for NAS operating on a PRIMECLUSTER system.
This is required for scalable operation and standby operation (cold standby) with the NetApp Filer.
Hereinafter, NetApp Filer (ETERNUS NR1000F series) is referred to as NAS.

This software provides the following features:

Feature

Description

Environment Setup

Environment setup tool to enable clustering of NAS on PRIMECLUSTER

Start and Stop Control

Control export on NAS

Releases the file lock

Releases the file lock on NAS

Monitoring the NAS-Cluster

In the NAS-Cluster in which the controller is made double with two NAS devices, the failover of the NAS-Cluster is done even when data cannot be accessed by the network failure between the cluster node and the NAS devices.(optional)

Setup and Operation Commands

Commands used for setup and operations

Environment Setup

To enable clustering of NAS, it is required that NAS is registered on userApplication (cluster application) as a "resource". PRIMECLUSTER Wizard for NAS provides an interface to do it. For details, refer to "Chapter 2 Environment Configuration".

Start and stop control

Along with the userApplication state transition, PRIMECLUSTER Wizard for NAS automatically control the export/unexport of the NAS volume. In standby operation, PRIMECLUSTER Wizard for NAS also release the file lock of the operating node in which a Netapp resource failure occurs during Online processing.

File locks release

Release the file lock when the userApplication switch and the node goes down.

In standby operation, the NFS file lock on the NAS device is released when userApplication is started.

In scalable operation, the NFS file lock on the NAS device is released, if PRIMECLUSTER Wizard for NAS detects the userApplication failure and the node down on another node.

Monitoring the NAS-Cluster (Control facility for the NAS-Cluster)

In the NAS-Cluster in which the controller is made double with two NAS devices, the failover of the NAS-Cluster is done even when data cannot be accessed by the network failure between the cluster node and the NAS devices and service can be continued. When the controller in the NAS device breaks down, the NAS-Cluster does the failover. But, when the network failure is done between the cluster node and the NAS device, the NAS-Cluster does not failover.

Setup and Operation Commands

PRIMECLUSTER Wizard for NAS provides auxiliary commands to discontinue or restart monitoring resource. For details, refer to "Chapter 4 Command".

If you need a recovery of the NAS-Cluster after its failover, refer to "3.4 Recovery sequence after control facility of the NAS-Cluster".
