  1. 1. HP-UX 11iv3 Method to Set Up Multiple Clones with Dynamic Root Disk Dusan Baljevic 2014
  2. 2. Acknowledgements • These slides have been used in various presentations in Australia over the last four years. This is a work-in-progress. • I bear full responsibility for any error, even though it is purely unintentional. • I cannot claim credits solely, nor can I claim that I know everything about Unix. I consider myself to be a Unix Apprentice. For that reason I need to give special credits to our colleagues Nobuyuki Hirota (TCE&Q BCS ERT), Daniel Bambou (TC&Q BCS ERT), and Leon Strauss (GSE) for their continuous support, advice, comments, and guidance. • Wisdom of many helped in creation of the presentation (seminars at HP, HPWorld, ITRC/HPSC forums, HP Ambassadors and Unix Profession forums, HP Education courses, individual contributions on the Net). 2
  3. 3. 3 HP-UX DRD Multiple Copies of Targets Initial scenario - HP-UX 11iv3 server with four disks. * Current boot disk is disk7: disk5 HP 73.4GMAU3073NC disk6 HP 146 GST3146707LC disk7 HP 73.4GMAU3073NC disk9 MSA/P2000 VOLUME * Initial clone is disk5. * Then, we create another clone via DRD on disk6. * The question is: can we use the previous DRD clone disk5? The answer is: YES!
