Dumping Processor Memory to Disk Online
•
If dumpfile does not exist, RCVDUMP creates it.
•
If dumpfile already exists, it must be empty. Its EOF must be zero.
To empty an existing dumpfile:
> FUP PURGEDATA dumpfile
7. Dump the memory of the processor to a disk file in either of two ways:
•
Issue the TACL RECEIVEDUMP command, which runs the RCVDUMP utility:
> RECEIVEDUMP / OUT dumpfile / cpu , { 0 | 1 }
•
Run the RCVDUMP utility directly.
The syntax of the RCVDUMP command is:
RCVDUMP [ / run-option [ , run-option ] _ / ] dump-file ,
cpu, { X | Y } [ , param [ , param ] ] ]
param is either:
{ PRIME | NOPRIME }
{ FULL | PARTIAL }
or:
ONLINE (You cannot also specify another param or bus X|Y.)
For example, you could enter:
> RCVDUMP dumpfile , cpu , { X | Y }, FULL
RCVDUMP begins copying the dump in a compressed format from the
specified processor cpu, over the specified ServerNet X or Y fabric, into the
disk file dumpfile. The processor performing the dump is the one in which
the TACL command interpreter is running.
For an explanation of the RCVDUMP messages, see the TACL Reference
Manual.
8. Monitor the dump to ensure it finishes successfully.
As the dump proceeds, the status of the processor being dumped should change
in the Processor Status dialog box. When the dump is finished, the status of the
selected processor changes to indicate the completion of the dump.
In addition, RCVDUMP sends the following message to the terminal from which it
was run:
CPU n has been dumped to dumpfile
9. Ensure the dump was successful by checking the size of dumpfile:
> FUP INFO dumpfile
The end-of-file pointer (EOF) should not be zero.
