Initiating a dump with VMDUMP

Start the VMDUMP process with the CP VMDUMP command.

Procedure

Issue the following command from the 3270 console of the z/VM® guest virtual machine:

#CP VMDUMP

Results

z/VM CP temporarily stops the z/VM guest virtual machine and creates a dump file. The dump file is stored in the reader of the z/VM guest virtual machine. After the dump is complete, the Linux® on z/VM instance continues operating.

You can use the TO option of the VMDUMP command to direct the dump to the reader of another guest virtual machine of the same z/VM system.

Example

To write the dump to the reader of z/VM guest virtual machine linux02 issue:

 #CP VMDUMP TO LINUX02
