HP-UX 11iv3 Method to Set Up Multiple Clones with Dynamic Root Disk

Dusan Baljevic 2014

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).

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!
