I had to rebuild a Sun E450 by way of re-configuring all the metadevices. Out of the 5 controllers on the box, 3 of them (3!) were bad, meaning there wasn’t one good submirror set in the whole system. Every one of the RAID1 metadevices had “Maintenance” on them due to the bad controller(s).

I wrote up all the details and stored it on our intranet, but what I would like to say is that the articles found in this series — http://supportforum.sun.com/hardware/index.php?t=msg&goto=13076&rid=0 were a great help. Most of it was refresher, as there’s nothing there I haven’t done before, but since it was 7-8 years ago… it was ver nice to have such clearly written examples and instructions.
