To remove drive assignment in Data OnTap use:

To unassign:
disk assign 0b.30 0b.29 0b.28 0b.27 -s unowned -f

Run that for whatever disks you are trying to remove assignment for (do it from the head that currently owns the disk).

Thanks for your feed back. It would be nice if you could supply your Data ontap version. As that command had perfectly worked for me on Data Ontap 7.2.3. We are upgrading soon to 7.2.6.1. I will update this post, when I get to try this command on new release.

This didn’t work for me. In fact, it marked the disk as “failed” when I ran the “disk assign” part.

I recovered from that by going into Advanced mode (priv set advanced) and then using “disk unfail “.

From there, to unassign the disk, I used “disk remove_ownership “. Then I went back to normal mode with “priv set admin”.
