Use the zgetdump command to copy an NVMe dump to a
file in the file system.
About this task
By default, the zgetdump tool takes the dump device as input and writes
its contents to standard output. To write the dump to a file system, you must redirect the output to
a file.
Procedure
Assuming that the dump is on an NVMe partition /dev/nvme0n1p1 and
you want to copy it to a file named dump.elf:
# zgetdump /dev/nvme0n1p1 > dump.elf
What to do next
You can use zgetdump -i to display information about the dump. See Printing the NVMe dump header for an example. For general information about
zgetdump, see zgetdump - Copy and convert kernel dumps or the man page.
