Problem

When I replace a failed disk, my filer doesn't see the disks immediately. The Filer Status page is complaining "Assign unowned disks".

Solution

Your filer is set up with software disk ownership, presumably so that clustered filer heads can share the same shelves. As a side-effect, you must set the "disk ownership" of disks after you replace them.

Scenario: two disks failed, 0b.19 and 0b.23. NetApp has supplied replacement disks, which have been inserted and have gone green. The filer is still complaining about "insufficient spare drives", and says "Assign unowned disks". The FilerView thing isn't showing the inserted disks in the Disk Management page.

Note that the replaced/inserted disks 0b.19 and 0b.23 are not in the above list. (The list is unsorted, so it is hard to tell immediately.)

Use the disk assign command to assign the inserted disks:

nas02> disk assign all
The parameter all refers to all currently unassigned disks.

Now confirm that the assignment worked:

nas02> disk show

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
