Creating dumps on z/VM with VMDUMP

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.

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.

The following sections take you through the process of creating a dump with VMDUMP.
