Linux on System z does support hibernation. It is documented as suspending and resuming, but it is not a suspend like you suspend a laptop. It is more like hibernation where all active memory is written to a swap DASD before Linux stops. See the device drivers book for the level of Linux that you have ( http://www.ibm.com/developerworks/linux/linux390/documentation_red_hat.html or http://www.ibm.com/developerworks/linux/linux390/documentation_suse.html) to read more about it.
However, for the most part you probably only want to issue CP commands, so use the vmcp Linux command to do that (as others have stated.) If you want to update CMS files on a minidisk owned by the Linux server, just use another id to do that. Detach the disk from Linux (or re-link it read only), then link and access it r/w from another id and make the updates. No need to stop Linux for either of these methods.
