Recovery Operations for Problems Detected by
OSM
Suppressing Problems and Alarms
In certain cases, you might want to acknowledge or suppress a particular problem, to
stop it from propagating a known problem all the way up to the system level. That way,
it will be easier to identify other problems that might occur. For more information on
OSM problem management features such as deleting or suppressing alarms and
suppressing problem attributes, see the
OSM Service Connection User’s Guide (also
available as online help within the OSM Service Connection).
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 .
