Processors and Components: Monitoring and	Dumping a Processor to Disk
Recovery

For automatic dumping and reloading of halted processors, use the HP Tandem Failure Data System (TFDS). To dump automatically, TFDS must be configured on the system before the halt occurs. However, you can also bring up TFDS following a halt and use the TFDSCOM command ANALYZE CPU to obtain information about the failure.

If you did not have TFDS configured to take the processor dump, you can use the RCVDUMP utility to take the dump.

•If your service provider determines that a processor halt is divergence-related, you might be directed to dump the entire processor before reloading it. In this case, use the RCVDUMP command, as follows:

°

°

Use BLADE ALL parameter option.

Do not specify ONLINE or PARALLEL parameters.

See Using RCVDUMP to Dump a Processor to Disk on page 9-17.

•If your service provider determines that a processor halt is not divergence-related, you might be directed to reload the processor while excluding the PE for one Blade Element, which is then dumped before being reintegrated. In this case, perform the reload (see Reloading a Single Processor on a Running Server on page 9-10),then use the RCVDUMP command as follows:

°

°

If more than one Blade Element is in the Stopped state, use the BLADE parameter and specify the bladeId (A, B, or C) of the PE to be dumped. (If only one Blade Element is in the Stopped state, it is not necessary to use the BLADE parameter.)

Specify the PARALLEL parameter.

See Using RCVDUMP to Dump a Processor to Disk on page 9-17.

•If a dump is to be taken following a system load, as described in Performing a System Load From a Specific Processor on page 15-11,options for taking dumps include:

°

°

After the processor (0 or 1) has been loaded with a Blade Element omitted, use RCVDUMP with the PARALLEL option.

You can dump any of the remaining processors either by dumping the entire processor before reloading them (use RCVDUMP without specifying the ONLINE or PARALLEL options), or reload with a Blade Element omitted, then dump that Blade Element using RCVDUMP with the PARALLEL option.

•If you are directed to dump a single PE that is running, use the RCVDUMP command, as follows:

°

°

Specify the ONLINE parameter.

Do not specify the Blade ID (RCVDUMP will choose the first running PE).
