Kris,
A very important step is to make sure you have created a new VM directory with the old volume label references changed to the new ones and re-wrote the directory to the new SYSRES (or IPL) volume before shutdown, or your scheme will not work properly...

So to reiterate: 1) Install vanilla z/VM with default labels at highest addresses (no duplicate volsers exist) 2) Shut door, get off email, get off IM :)) 3) Clone to target disks (now duplicates exist - start the clock) 4) IPL new clone on target LPAR (3 minutes) 5) Run IPWIZARD on integrated 3270 console (5 minutes) 6) Get 3270 session and relabel volsers per documentation - I use sec 4.11 of the Virt'n cookbooks (15 minutes) 7) SHUTDOWN REIPL and cross fingers (no more duplicates) So in this example the duplicate volsers exist for about 23 minutes. Yes, something could go wrong in this timeframe, but I haven't lost much. Does this sound better? > my customer's operators caused such a mess in a disaster test weekend ... And looking on the bright side: this is when you really learn z/VM :)) "Mike MacIsaac" <mike...@us.ibm.com> (845) 433-7061 ******************************************************************************************** This message, including any attachments, contains confidential information intended for a specific individual and purpose, and is protected by law.
