NonStop Operations Guide for H-Series and J-Series RVUs

Recovery operations for a system console are not discussed in this guide. For recovery procedures
for a system console and the applications installed on the system console, see the planning guide
for your NonStop system.
Preparing for and Recovering from Power Failures
You can minimize unplanned outage time by having procedures to prepare and recover quickly
from power failures, as described in Chapter 16 (page 170).
Stopping and Powering Off the System
HP recommends a specific set of procedures for stopping a NonStop system and powering off its
components, as described in Chapter 17 (page 175).
Powering On and Starting the System
HP recommends a specific set of procedures for powering on and starting an NonStop system or
its components, as described in Chapter 17 (page 175).
Creating Startup and Shutdown Files
HP recommends a specific set of procedures for creating startup and shutdown files on an NonStop
system or its components, as described in Chapter 18 (page 199).
Performing Preventive Maintenance
Routine preventive maintenance consists of:
• Dusting or cleaning enclosures as needed
• Cleaning tape drives regularly
• Evaluating tape condition regularly
• Cleaning and reverifying tapes as needed
Routine hardware maintenance procedures are described in Chapter 19 (page 218).
Operating Disk Drives and Tape Drives
Refer to the documentation shipped with the drive.
Responding to Spooler Problems
Refer to the Spooler Utilities Reference Manual.
Logging On to a NonStop System
Many operations and troubleshooting tasks are performed by logging on to your NonStop system
from a system console and using the TACL command interpreter or one of the OSM applications.
For example, the TACL command interpreter allows you to access SCF, which you use to configure,
control, and collect information about objects within subsystems. For examples of OSM tasks and
functions, see “Overview of OSM Applications” (page 29).
System Consoles
A system console is a personal computer approved by HP to run maintenance and diagnostic
software for NonStop systems. New system consoles are preconfigured with the required HP and
third-party software. When upgrading to the latest RVU, software upgrades can be installed from
the HP NonStop System Console Installer DVD.
System consoles communicate with NonStop systems over a dedicated service LAN (local area
network). System consoles configured as the primary and backup dial-out points are referred to
as the primary and backup system consoles, respectively.
