NonStop NS-Series Operations Guide (H06.12+)

Recovery Operations for Problems Detected by OSM
Recovery operations depend on the particular problem, of course. Methods of determining the
appropriate recovery action include:
• Alarm Details, available for each alarm displayed in OSM, provide suggested repair actions.
• The value displayed by problem attributes in OSM often provide clues to recovery.
• EMS events, retrieved and viewed in the OSM Event Viewer, include cause, effect, and
recovery information in the event details.
• Check the section in this guide that covers the system resource—for example, Section 11,
Tape Drives: Monitoring and Recovery— for information on using the SCF and other tools
to determine the cause of a problem. Then follow the directions in the Recovery Operations
subsection in the relevant section.
Replacing a system component that has malfunctioned is beyond the scope of this guide. For
more information, contact your service provider, or refer to the Support and Service Library on
page 1-12.
Monitoring Problem Incident Reports
The OSM Notification Director generates problem incident reports when changes occur that
could directly affect the availability of resources on your Integrity NonStop server. The Incident
Report List tab on the Notification Director dialog box allows you to view, sort, authorize, and
reject incident reports. The Notification Director allows you to forward notifications to your
service provider if your system is configured for remote dial-out.
Using SCF to Monitor the System
Use the Subsystem Control Facility (SCF) to display information and current status for all the
devices on your system known to SCF. Some SCF commands are available only to some
subsystems. The objects that each command affects and the attributes of those objects are
subsystem specific. This subsystem-specific information appears in a separate manual for each
subsystem. A partial list of these manuals appears in Appendix C, Related Reading.
Determining Device States
This subsection explains how to determine the state of devices on your system. For example, to
monitor the current state of all tape devices on your system, at an SCF prompt:
-> STATUS TAPE $*
Example 3-1 shows the results of the SCF STATUS TAPE $* command:
