Scanning for Alarms and Running Diagnostics with TSM
In addition to displaying attributes as explained in OSM and TSM Client Software on
page 5-3, you can also use the OSM Service Connection or the TSM Service
Application to scan for alarms and run diagnostic tests. For more information on
viewing alarms, refer to the online help within each application.
An alarm is a message, similar to an event message, that reports detected faults or
abnormal conditions. The Alarm Summary dialog box identifies the alarms associated
with a resource and indicates the severity of the alarms. The TSM Service Application
also uses color and icons to identify alarm conditions in the System, Physical, and
Logical views.
The OSM Service Connection and the TSM Service Application also provide several
actions to enable you to test and verify the status and operation of a ServerNet/FX
adapter. For more information about the tests you can run, refer to the online help
within each application.
OSM and TSM Notification Director
The OSM and TSM Notification Director applications receive incident reports from
NonStop S-series servers, display incident reports, and allow you to take action or to
forward the reports to your service provider for resolution. Incident reports notify you of
changes that could directly affect the availability of system resources, changes in
hardware configuration, and changes in software configuration.
For more information about using these applications, refer to the online help within
each application.
Resolving Problems
SCF, OSM, and tSM are very effective in solving ServerNet/FX adapter subsystem
problems. The following suggestions are provided to help you solve ServerNet/FX
problems using these tools:
•
Use the SCF STATS LBU command for information about OSI Layer 2 statistics.
•
Use the SCF STATUS SUBNET command to determine which clusters are up or
down and which links have continuity (data flow around the ring).
TMDS, which is provided on NonStop K-series systems running the D-series NonStop
Kernel operating system, provides a STATUS RING command that displays a view of
the entire FOX ring. You can run TMDS from a NonStop S-series system running the
G-series NonStop Kernel operating system by logging onto a remote TACL to access a
NonStop K-series system running the D-series NonStop Kernel operating system and
then running TMDS at the remote system.
When examining the TMDS STATUS RING display, compare the X-bus and Y-bus
views of the ring and compare the view going to the right with the view going to the left.
Different clusters may have different views of the ring because of ring failures. For
