z/VM guest example
You can initiate a dump for Linux® instances running under z/VM® by using VMDUMP.
Procedure
To initialize a dump with VMDUMP, issue this command from the console of
your z/VM guest virtual machine:
#cp vmdump Results
Dumping does not force you to perform an IPL. If the Linux instance ran as required before dumping, it continues running after the dump is completed.
