Creating a kernel dump of Linux in LPAR mode or of a z/VM guest
The dump tools for Linux in LPAR mode and Linux as a z/VM® guest include stand-alone dump tools, kdump, and zgetdump.
With kdump in place, a dump is triggered automatically by a kernel panic. Use the zgetdump command for a live-system dump.
For Linux as a z/VM guest you can also use VMDUMP.
For details about the dump tools, see Using the Dump Tools on Red Hat® Enterprise Linux 9.2, SC34-7751.
