This should work with the vmur tool. The target reader has to be empty and you have to punch the files in the correct order: # vmur pun -r -u <guest> image # vmur pun -r -u <guest> parmfile # vmur pun -r -u <guest> initrd We described the (local) procedure in the Device Driver Book (Chapter: vmur - Work with z/VM spool file queues): http://public.dhe.ibm.com/software/dw/linux390/docu/lk32dd04.pdf Michael ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
