7-Mode to CDOT

Can anyone comment on performing an actual conversion from 7-Mode to CDOT?  What resources did you use?  What procedure did you follow? Was it done in the field? By a customer?


I'm worried that KB 1013517 might not be the whole story...


  1. It's kind of top-secret. You can find it with a search on kb.netapp.com, but you just get a note about needing to ask for access. This makes me wonder if I'm missing some updates.

  2. The caution in big red letters about needing to be a NetApp or partner employee ("don't try this at home") is a bit disconcerting.


  3. The procedure given in 1013517 seems too simple. It basically boils down to Loader option 7. ("Install new software first.") That seems too simple. No firmware update? No loader update? No BIOS flash? No netboot? 

  4. A simple question earlier here on a related subject turned up complex considerations on the upgrade path and not much agreement.

Update:  I'm just trying to focus on the OS part of the conversion. Assume no data volumes at all. I just want to move completely empty, disk-wipeable filers from 7-Mode to CDOT 8.3. We have lots of 2240-2 filers that should make nice CDOT platforms.  Yes, we are adding 10GbE mezzanine cards for the cluster interconnect.


FInal updateI followed the KB instructions and the update went smoothly.  The upgrade procedure is convenient and well documented.  It really was as simple as it appeared, and other than the disk wipe, it's not much different than an ordinary within-mode OS update, which is easy to do.   Just get the license keys first and upgrade the BIOS if needed. (The SP upgrade comes with the OS. I updated 7-mode to the tip revision first just to be safe.)
