Creating dumps on z/VM with VMDUMP

Use VMDUMP to create dumps on z/VM systems, using the z/VM reader as the dump medium.

Before you begin

Do not use VMDUMP to dump large z/VM guests; the dump process is very slow. Dumping 1 GB of storage can take up to 15 minutes depending on the used storage server and z/VM® version.

About this task

This section describes how to create a dump with VMDUMP, how to transfer the dump to Linux, and how to convert the z/VM dump to a convenient format.

VMDUMP does not need to be installed separately.
