Netapp Data Ontap 7-Mode to Clustered Ontap Steps
In this tutorial I will show you which steps are necessary to convert your Data Ontap 7-mode system to Data Ontap Clustered Mode
The latest release as of writing this tutorial is Data Ontap 8.2. If you are currently running 7-mode, first upgrade to 8.2 (preferably using Upgrade Advisor on the NOW website) and then follow on with the steps below.
WARNING: When you convert from your 7-mode system to clustered mode, it will erase your entire filesystem. All aggregates need to be destroyed and re-created.
Disk Ownership
Make sure you have about 3-5 disks owned by each controller. You will then have more control as to how you would like to create your aggregates. Otherwise the install will throw all disks into the one aggregate.
Clustered Ontap Change of Boot Loader
when you see Hit [ENTER] to boot immediately, or any other key for command prompt, press any key to enter into the boot loader
LOADER-A> set defaults
LOADER-A>> setenv bootarg.init.boot_clustered true
LOADER-A> setenv bootarg.bsdportname e0M
LOADER-A> set date DD/MM/YYYY (Example 21/05/2013)
LOADER-A> priv set advanced
LOADER-A> sp setup (Configure the service processor so you can get to the Storage System remotely)
After you have finished configuring the Service Processor continue on with the next step
LOADER-A> boot_ontap
Press CTRL-C to enter into the boot menu
Once in the boot menu select option 4 to Clean configuration and initialize all disks.
WARNING: This will erase your entire storage system, so unless you are doing this on a brand new system, a demo system, or an existing system that does not have any data on it, do not continue any further.

at what point in this procedure should i apply the advanced drive partitioning?
Hi Paul, it’s much simpler now. As long as you are running Ontap 9.3 and above you can boot the system into the boot menu (press ctrl-c when you see ‘press ctrl-c for boot menu) and select advanced drive partitioning. From within that menu you can remove partitions and drive ownership from both nodes, then upon reboot it will setup ADP for you. Keep in mind that this process does destroy any existing aggregates you have on the system
