PRIMECLUSTER Wizard for NAS is a software product that must be installed when the ETERNUS NR1000F series (NetApp(TM) Filer: Refers to the disk device manufactured by Network Appliance Inc. Hereinafter abbreviated to NAS device.) is being used as the PRIMECLUSTER shared disk device. This software releases the NFS file lock that can cause a problem upon the occurrence of a node down or application error, and then performs failover.
According to the state transition of userApplication, automatic control of export/unexport is allowed for the volume of the network attached storage (NAS) device. For standby operation, the file lock, retained by the old operation node, is released at startup.
PRIMECLUSTER Wizard for NAS does not monitor errors in the NAS device. Other resources, however, support error detection and failover control.
PRIMECLUSTER GLS monitors the access path to the NAS device.
The RemoteFileSystem resource, which allows remote file system mounting control, monitors accesses to the volume.
The environment setup wizard for running a NAS device as a shared disk on PRIMECLUSTER allows you to configure a cluster environment based on a NAS device easily and safely.
