If you have to re-IPL in order to free the system, please use the PSW RESTART feature from the HMC. This will force a dump, before re-IPLing itself.
You should also "play" with this process in order to make sure your system is properly set up to handle dumps. See the z/VM V5R2.0 CP Planning and Administration guide for the amount of storage needed, and how to dedicate space you need for it (see the section on the CP_OWNED Statement).
To "play" with this process, issue a SNAPDUMP during a time frame least disruption to your system (it temporally holds/halts all activity while dumping in use CP storage) to the OPERANTS reader (RDRL). The DUMPLOAD command then downloads the dumps to disk (the command can be issued just like that, with no parameters, so long as your A disk is large enough to hold it).
Al these commands are located in the z/VM V5R2.0 CP Commands and Utilities Reference. All these publications can be found at: http://www.vm.ibm.com/library/
And so long as you are running a supported release, please just open a PMR. Someone from here can always help with the process. Thanks and Best Regards,
Kurt Acker

No VM System dump. No Performance Toolkit records. This is the first time that I remember this ever happening so I am not real familiar with dumping the VM system. Would there been a way I could have force a dump of the VM system?
Thanks.

What kind of VM system dump did you get? I looked, but didn't find
a problem record for this. Was any monitor or Performance Toolkit
history files available for the production system?
