Disk partitioning during root aggregate migration

[haughty bobcat]

I have FAS8300 with 3 shelves with following disks installed:
SSD - 12 bays (4Tb)
SAS - 24 bays (1.6Tb)
FSAS - 56 bays (14Tb)
During system initialization a part of FSAS disks was assigned and partitioned with ADPv1(root-data).
Now I wanted to migrate root aggregates to SAS disks, but after disk assignment to one of the nodes partitions are not created on them. And after root aggregate of one node was migrated to selected disklist this aggregate now occupying whole disks not a disk partitions.
Is there any method to create ADP partitions on that disks to migrate root aggregates?

Yeah, after the fact, if you want to use partitions for root you must manually create partitions. There is another thread about this here someplace. I commented about it.
If it’s a clean system, you’re better off just reinitialzing the system. Do the option 9 on both. Then simply unplug the drives you don’t want adp on. Let the system do its thing then after ONTAP is ready plug them back in and assign as needed

I found this topic with similar problem: https://discord.com/channels/855068651522490400/1141758251747246202
I think there is no truly "manual partitioning" only "copying" partition layout from already partitioned disks, is it right?

There is a manual partitioning. Not recommended unless you are very familiar with what you are doing. Better to start over reinit when possible

Looking at that link, follow the kb and look at the pre ONTAP 9.5 directions. Like I said, not for the novice. Not responsible if you break your system

I have no data on it yet. So I have to give it a try 🙂

hmm, it seams that link was removed, could you post a PDF-file created from that page?

Here is the link:

If you can’t access it fully or view it fully then you are not allowed (meaning not a fully user facing kb even though it says it is). I will not share pdf/kb articles to be safe. If you have a local Netapp se, maybe you can get them to share. Sorry

[haughty bobcat]

this link is ok. i already read that kb article. i'm interested in this kb article: https://kb.netapp.com/onprem%2Fontap%2Fhardware%2FHow_to_partition_a_drive_manually_in_ONTAP_9

That one says public. You should be able to see the whole thing. Make sure you are logged into the kb site

i'm sure, i'm logged in

Ah, mine says at the bottom “Partner Notes”, so yeah I shouldn’t share that. You should get your local Netapp engineer involved. Or open a case and have them share it. I can get in trouble for sharing items that aren’t supposed to be.
