5.3 Basic Running RequirementsNotification Processing Center (NPC) is a separate software application from RAIDWatch primary and secondary agents, and from RAIDWatch Manager, and it must be manually configured and run (and re-run after a host computer reset) in order for notifications to be sent out.
Installation and configuration of the NPC is accomplished using the same program and interface as that for the installation and configuration of the Primary and Secondary agents.
In order for NPC to work, it must be installed and run on the same host computer as a Primary Agent. Once NPC is installed, it must be configured to send the types of notifications you want to receive.
IMPORTANT:
For NPC to function on NT servers, the "Windows Messaging Service," "Personal Fax," "Internet Mail," and "Telephony service" must be installed and running. Windows Messaging can be used to receive and store faxes, and for other kinds of messages.
NPC and Primary Agent can be installed redundantly on two different servers in case the Primary Agent, NPC module, or the server itself, should fail. If the Primary Agent or NPC should fail, the Primary Agent and NPC installed on another server will continue event notification. This method is applied for the consideration that fatal system failure might occur unnoticed at the time when the only NPC or Primary Agent is unable to function.
Redundant NPC modules can not be installed without Primary Agents. Run the RAIDWatch configuration procedure and enable this function by designating another server as where the redundant modules will be installed. Primary Agent and NPC must then be installed manually on that particular server (either a RAID server or not). The installation utility does not automatically add these modules to the selected server.
