service processors (MSPs). (The workstation can also communicate directly with the
MSPs on the Himalaya S-series server when the NonStop Kernel operating system is
running.)
A service processor (SP) is a physical component of the Himalaya S-series server that
controls environmental and maintenance functions. The MSPs provide basic service
processor functions as well as a TSM workstation port, the modem port for remote
support functions, and system-load control. The enclosure containing processors 0 and
1 contains the MSP pair.
Event Viewer Server Manager
The Event Viewer Server Manager on the Himalaya S-series server is a persistent
process that routes messages between the TSM EMS Event Viewer on the workstation
and event server and summary server processes on the Himalaya S-series server. Event
server processes retrieve events. A summary server is a persistent process that maintains
a summary of all the events in a specified event log.
TSM Components on the Workstation
The TSM client software resides on the workstation, and comes installed on all TSM
workstations provided by Tandem. The TSM client software consists of the following
applications:
•
TSM application
•
TSM Notification Director
•
TSM Event Management Service (EMS) Event Viewer
TSM Application
You use the TSM application to establish a connection with a Himalaya S-series server,
even when the NonStop Kernel operating system is not running.
When the NonStop Kernel operating system is running, you will usually communicate
with the Himalaya S-series server using a service connection. A service connection
provides a comprehensive service and maintenance picture of the server and is used to
perform most service management tasks.
When the NonStop Kernel operating system is not running, communication takes place
over a low-level link. This link is used for system installation, system startup, and
certain recovery operations. You can also communicate with a Himalaya S-series server
over a low-level link when the operating system is running.
TSM Notification Director
The TSM Notification Director receives notifications and incident reports from the
Himalaya S-series server, displays them, and allows you to take action or forward the
incident reports to your service provider for resolution. The TSM Notification Director
runs on the TSM workstation at all times, even when the TSM application is not being
used.
