RECEIVEDUMP Command (Super-Group Only)

Use the RECEIVEDUMP command to dump the memory of a processor to a disk file.

The processor being dumped can be running or halted. This command executes the

RCVDUMP program. The processor from which the RECEIVEDUMP command is run

must have X or Y fabric (G-series RVUs) or X bus or Y bus (D-series RVUs) access to

the processor being dumped.

This command is not supported in H-series systems, use RCVDUMP instead.

For G-series RVUs, you must have the super ID (255,255) to issue this command.

For D-series RVUs, you must have a super-group user ID (255,user-id-number).

When a processor is dumped to disk, the RCVDUMP utility copies the dump in a

compressed format from the specified processor to a disk file.

Pressing the BREAK key while the RECEIVEDUMP command is running causes

RCVDUMP to abend or stop, and leaves the memory dump unfinished. If this happens,

you must purge the dump file and restart the RECEIVEDUMP command.

G-Series Syntax

dump-file

is the name of the disk file to which the dump is to be written.

cpu

is the number of the processor that is to be dumped. Specify cpu as an integer in

the range from 0 through 15.

fabric

specifies the ServerNet fabric to be used for the dump operation. The default fabric

is the X fabric. Possible values are:

0 = X fabric

1 = Y fabric

Caution. This command should be used only as part of a documented processor dumping and

recovery procedure. Refer to the sections Processors: Monitoring and Recovery and Starting

and Stopping the System in the NonStop S-Series Operations Guide.

If a memory dump is requested as part of a recovery procedure, for processors with more than

2 gigabytes of memory, use the TFDS memory dump facility to ensure that the dump occurs in

a timely fashion. Otherwise, use either RCVDUMP or the TFDS facility. TFDS must be

configured on the system before the halt occurs.
