Shadowset volume management during upgrade?

» close window

The Question is:

Can I server our  system disk - a shadow set - and do my Multinet 4.3
upgrade on one disk. If it failed, I simply delete all the files then
rejoin the disk reboot the system. This way can avoid the system disk
corruption??? Do you think it will work better than so called restore the
system disk??? P.S. The operating system on out Alpha 4100 cluster is
OpenVMS v 7.1-2
 Many thanks ahead.

The Answer is :

  Assuming the shadowset volumes were split up correctly and that all of
  the volumes were in a consistent state when split, when the volumes are
  later reconstituted into a shadowset you can choose which shadowset
  volume will be the initial shadowset master.
  If you simply add the upgraded volume to the existing shadowset, it
  will be overwritten with the contents of the existing shadowset
  volume(s), erasing the effects of the upgrade.  If you dismount the
  shadowset, then start to form the new shadowset based on the upgraded
  volume, the other shadowset member volume(s) will be overwritten by
  the contents of the updated volume.
  The use of Multinet or other product is irrelevent to the question.
