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.

All the tutorials included on this site are performed in a lab environment to simulate a real world production scenario. As everything is done to provide the most accurate steps to date, we take no responsibility if you implement any of these steps in a production environment.


    • 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
