Failover Cluster Detection
In the case of a service group experiencing a service incident, e.g. a node failure, the cluster manager acts upon the failover policies and initiates a failover of service groups to another available node. Failover detection rules will evaluate relevant entries in the cluster log as well as use cluster utilities to inform one about the events that occurred during failover.
Service Group Monitoring
VCS Service Groups contain critical resources of a cluster, typically interfaces, mount points or file systems. If a service group fails or becomes unavailable, resources are impacted. In order to be on top of all the service group impacting events, the NiCE Veritas Cluster MP includes several monitors dedicated to file system and service group monitoring. Furthermore, the MP complements the monitoring provided by the Microsoft Linux management packs.
Comprehensive Cluster Server Discovery
The Veritas Cluster Server (VCS) consists of numerous objects like nodes, service groups, mount point and file systems. Each object has its own properties like failover policies, service labels, log paths and identifiers. In a large environment, oversight of important components is easily lost. The ‘out-of-the-box discover’ allows discovery of all VCS objects including an extensive list of properties for each object.
In an environment of ever increasing business demands, critical applications need to be available 24/7, with a fault tolerant system. However, fault tolerant systems are not cost effective. As such, there is a business need for a cost effective application which provides this functionality.
