• 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!
