To the system administrator, the Sun Cluster system is a set of servers (nodes) cabled together, sharing storage devices. The system administrator sees software that performs specific tasks:
Specialized cluster software integrated with Solaris software to monitor the connectivity between cluster nodes
Specialized software that monitors the health of user application programs running on the cluster nodes
Volume management software that sets up and administers disks
Specialized cluster software that enables all nodes to access all storage devices, even those not directly connected to disks
Specialized cluster software that enables files to appear on every node as though they were locally attached to that node
System administrators need to understand the following concepts and processes:
The interaction between the hardware and software components
The general flow of how to install and configure the cluster including:
Installing the Solaris Operating System
Installing and configuring Sun Cluster software
Installing and configuring a volume manager
Installing and configuring application software to be cluster ready
Installing and configuring Sun Cluster data service software
Cluster administrative procedures for adding, removing, replacing, and servicing cluster hardware and software components
Configuration modifications to improve performance
The following sections contain material relevant to the preceding key concepts:
The following Sun Cluster documents include procedures and information associated with the system administration concepts:
