If the node hostnames are known, then you should also see the disk ownerships by hostname, otherwise you will only see the System IDs. # Shows System ID of the current controller, and ownership of all attached disks. You can boot into maint mode check and set the ownerships.

You will of course need to make some decisions about how those disks are used (aggregates, RAID groups, vol0 and the like) so I recommend you read the relevant documentation or get advice from someone who knows 7-Mode better than I do. A fairly 'safe' choice would be to assign all the disks that the node will own using maint mode, then use option 4 to scrub them before booting into ONTAP for the first time. I imagine the requirements for setting up a 7-Mode HA pair would be similar but I am not entirely sure. To make the scrub faster I do not usually assign all disks at this time later on I can change assignments for the other disks and run the remaining disk scrubs and RAID operations in the background while the filer is operating. On Clustered ONTAP each controller needs at least 3 disks for a root aggregate before it can start up so when I am installing a CDOT cluster I use maint mode to make sure that each node has at least 3 disks (and preferably a spare) before booting into ONTAP for the first time. Initialising/scrubbing those disks before you use them is a pretty good idea but can take several hours as the disks will be zeroed out (overwritten). However to initialise the controller you probably do need to have some disks owned by it. Option 4 won't touch any disks that aren't already owned by the controller you are running on. I am afraid of selecting this option before getting a clear idea.ДЄlso please reply me ASAP as I have down time only today. If yes I will dieДЄlso I didn't see any steps asking me to add the disks in the maintenance mode which one of my friend suggested before initializing (software ownership).Д¬ould someone who have experienced in adding controller please share your thoughts. When I select this option will it erases my data in my existing disks( 12 disks assigned to controller1 which is active now). The system reboots and displays the boot menu.Д.

Preparing for the upgrade on page 2 - DoneДў. I have attached the document with this thread.ДЎ. I found a document from Netapp and I am following as per it. Now we planned to add 12 more disks and enable the HA-pair(cf). Initially we bought this with 2 controllers but using one. The existing controller has 12 disks now and already assigned. Our scenario: We have a FAS2240-4 which was configured earlier with only one controller and the other controller was passive.
