Managing the HP SureStore E Disk Array 12H on Windows NT AutoRAID Manager Components AutoRAID Manager Components AutoRAID Manager software includes several components. The AutoRAID Manager Server and the AutoRAID Manager Client are required components that work together to manage the HP SureStore E Disk Array 12H. The exact combination of components you install will be determined by your system and network configuration. • AutoRAID Manager Clients - these required components provide the user interface for managing the HP SureStore E Disk Array 12H. Two clients are provided: the AutoRAID Manager for Windows client and the ARM command line utilities. The Windows client can be used to manage disk arrays remotely. The command line utilities can only be used to manage disk arrays from the host server. • OpenView Client for AutoRAID - this optional component runs under HP OpenView and automatically discovers and displays HP AutoRAID devices on the HP OpenView map. The HP OpenView client communicates with the SNMP agent. The OpenView Client is installed if OpenView Network Node Manager is installed on the client. • AutoRAID Manager Server - this required component is the core of the AutoRAID Manager. The AutoRAID Manager Server (ARMServer) is installed as a service on the host server to which the disk array is connected. The HP AutoRAID Manager service must be running to manage disk arrays using AutoRAID Manager. Installation of the AutoRAID Manager Server must be done from the host server console by a user with Administrator access. • Remote Management SNMP Agent - This optional component is installed on the server only if SNMP is installed. The AutoRAID Manager SNMP agent communicates with the HP OpenView client to provide the mechanism for broadcasting event information to network administrators and establish a communication link between the server and the client. • Failover Driver - this componentenables the operating system to exploit the performance and redundancy benefits provided by dual disk array controllers. During normal operation, the failover driver manages the transfer of host data to achieve optimum performance. If one of the controllers fails, the failover driver automatically stops using the failed controller and directs all subsequent I/Os to the remaining controller. The failover driver provides the same functionality regardless of whether the two disk array controllers are on the same SCSI channel or on separate SCSI channels. 208 Windows NT
