HP NonStop NS Halting One or More Processors, Reloading a Single Processor on a Running Server

Processors and Components: Monitoring and	Halting One or More Processors
Recovery

The best manual recovery operation for your processor halt scenario depends on the type of halt. You should record the halt information (as described in Identifying Processor Problems on page 9-7), and contact your service provider to help you determine the appropriate course of action.

This section describes the various options for Dumping a Processor to Disk and Reloading a Single Processor on a Running Server that you might be directed to use.

Halting One or More Processors

To place a selected processor or processors in a halt state and set the status and registers of the processor or processors to an initial state:

1.Log on to the OSM Low-Level Link.

2.On the toolbar, click Processor Status button.

3.In the Processor Status dialog box, select the processor to be halted or select all the processors to halt all of them.

4.Select Processor Actions>Halt.

5.Click Perform action.

6.A message box appears and asks whether you are sure you want to perform a halt on the selected processor or processors. Click OK.

Reloading a Single Processor on a Running Server

Sometimes one or more processors in a running server are not operating. For information on how to determine whether a processor is operating, see Monitoring Processor Performance Using ViewSys on page 9-7.

Unlike NonStop S-series, you don’t always have to wait until you dump the processor before reloading it. This section describes how, when appropriate, to exclude the processor element (PE) from one NonStop Blade Element during the reload operation, so you can get the rest of the processor running, take the dump, then reintegrate the PE back into the running processor.

After you have determined that a processor is not operating, check that the processor is halted. If it needs to be halted, see Halting One or More Processors on page 9-10).

Collect information about the reason for the halt (as described in Identifying Processor Problems on page 9-7)to send to your service provider along with the dump file. In the Low-Level Link Processor Status dialog box, write down the halt code and status message for the processor.

Your options for reloading a processor on a running server are:

•

•

Using TACL RELOAD to Perform Reload on page 9-11

Using the OSM Service Connection to Perform Reload on page 9-13

Following the reload, if TFDS is not configured to take the dump automatically, you can perform a dump of the omitted PE while normal operations resume on the reloaded PEs within that logical processor. See the Dumping a Processor to Disk on page 9-15.
