Hello,
Running Red Hat 6.6 under zVM 6.3. I had a guest hang and unable to issue
linux commands to force a kernel crash dump( echo c > /proc/sysrq-trigger ).
Any suggestions how that can be accomplished?
Thanks

guest's rdr device. You can then 'vmur receive --convert
/path/to/where/dump/goes' to import the vmcore to the Linux file system
