PRIMECLUSTER Wizard for NAS (PRIMEQUEST) 4.2 Configuration and Administration Guide - Linux -

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 by Oracle9i Real Application Clusters or the like and standby operation (cold standby) with the NetApp Filer.
Hereinafter, scalable operation by Oracle9i Real Application Clusters or the like is referred to as scalable operation; NetApp Filer is referred to as NAS.

Module structure

For NAS operation on PRIMECLUSTER, the module structure is as follows:

Environment Configuration Wizard	Environment configuration tool to enable NAS operation on PRIMECLUSTER
Detector	Releases the file lock on NAS in scalable operation Control facility of the NAS-Cluster(optional)
Scripts	Release the file lock and control export on NAS

Environment configuration

The environment configuration tool provides "Netapp" Wizard and "NETAPP" turnkey wizard that create userApplication in the PRIMECLUSTER RMS environment.

File locks release in scalable operation

The detector monitors the Netapp resource during scalable operation. In the event of a Netapp resource failure, the detector releases the file lock of the node in which the resource failure occurred.

Start and stop control

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

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.

If you need a recovery of the NAS-Cluster after its failover, refer to "3.3 Recovery sequence after control facility of the NAS-Cluster".
