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 and ETERNUS DX series.
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 | PRIMECLUSTER Wizard for NAS releases the file lock on NAS |
Monitoring the NetApp Filer-Cluster | In the NetApp Filer-Cluster in which the controller is made double with two NetApp Filer devices, the failover of the NetApp Filer-Cluster is done even when data cannot be accessed by the network failure between the cluster node and the NetApp Filer 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, scripts automatically control the export/unexport of the Netapp Filer(7-Mode) volume. When NetApp Filer(cDOT) or ETERNUS DX device is used, do not control the export/unexport. In standby operation, PRIMECLUSTER Wizard for NAS also release the file lock of the operating node in which a NAS resource failure occurs during Online processing.
Releases the file lock
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 NetApp Filer-Cluster (Control facility for the NetApp Filer-Cluster)
In the NetApp Filer-Cluster in which the controller is made double with two NetApp Filer devices, the failover of the NetApp Filer-Cluster is done even when data cannot be accessed by the network failure between the cluster node and the NetApp Filer devices and service can be continued. When the controller in the NetApp Filer device breaks down, the NetApp Filer-Cluster does the failover. But, when the network failure is done between the cluster node and the NetApp Filer device, the NetApp Filer-Cluster does not failover.
Setup and Operation Commands
PRIMECLUSTER Wizard for NAS provides auxiliary commands to discontinue or restart monitoring resource and command to set up ETERNUS DX beforehand. For details, refer to "Chapter 4 Command".

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