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

Monitoring Processors Automatically Using TFDS
HP Tandem Failure Data System (TFDS) should be used to proactively monitor processors and
manage processor halts. Configured and running before a halt occurs, TFDS can help determine
the type of recovery operation needed and:
• If TFDS determines that the entire processor should be dumped before reloading, it automatically
dumps, then reloads the processor.
• If TFDS determines that only the processor element (PE) for one Blade Element needs to be
dumped, it reloads the processor, excluding that Blade Element, dumps the Blade Element,
then reintegrates it back into the running processor.
• Collects the files necessary to analyze the problem.
• Sends halt information message to the EMS collector. If configured in OSM, a dial-out message
is sent to HP Global Support to notify them of the halt.
For more information on configuring and using TFDS, see the Tandem Failure Data System (TFDS)
Manual.
Monitoring Processor Status Using the OSM Low-Level Link
From the OSM Low-Level Link, use the Processor Status dialog box to determine if the processors
are running:
1. Log on to the OSM Low-Level Link.
2. On the toolbar, click the Processor Status button.
3. The status for all processors should be “Executing NonStop OS.” (See Figure 5.) If not, refer
to “Identifying Processor Problems” (page 128).

Monitoring Processor Status Using the OSM Service Connection
For NonStop BladeSystems, the OSM Service Connection displays processor-related components
under the Enclosure object (see Figure 6), which contains the Processor Blade objects, Logical
Processor objects, and ServerNet switch objects, in the tree pane. There can be up to 16 Processor
Blade objects per NonStop BladeSystem, representing the total of 16 processors. The Processor
Blade objects each contain the Memory Card and ServerNet interface card subcomponents. Each
ServerNet switch object contains Port subcomponents, which contain Fiber objects.
