Hi, I trying to scratch the entire AFF A300 cluster before sending it back to Netapp(trade-in). I did it on a FAS2620 without any problems, but on the A300 it interrups before it's completed (I have seen max 50% done).   I  boot ontap to menu, runs 9a on boths nodes, startup node1 into maintenance mode and then "disk assign all". After starting disk sanitization ( disk sanitize start -p 0x22 <disk> ), get some warnings/errors but it starts.   *> disk sanitize start -r 0d.01.0 Apr 23 08:06:55 [cl01-02:raid.assim.tree.noRootVol:error]: No usable root volume was found!

In fusion i have a solution but it appears that this solution is already configured.  This solution only has 16 SSD disks and that we can only use the data aggregates that the solution provides.  If i remove the data aggregates from the solution to then try and create only one lager aggregate , it only allows a one size to be created.  It appears that we cannot remove the two data aggregates and create one large one instead,. Is this a restriction due to ADP?  Due we just have to use the configuration that is shown below utilizing the two 4.8 TiB data aggregates ? Other systems allows creation of one large aggregate but they dont use ADP.   ... View more
