Replace a failed disk

luisdomingos — Thu, 05 Jun 2025 06:04:49 GMT

Hi all,

I have FAS 2040 with two aggregates with 12 disk and no spare disks, one aggregate in each controller.

One of the disks in one aggregate has failed and needs replacing.

What are the procedures for replacing this failed disk since I have no spare disks ?

Thanks in advance.

There are any steps/procedures needed from Ontap side ?

Thanks,

Hi,

you have to check, if the disk was assigned to the correct controller.

To be sure, you can assign the disk manually:

1.) check options disk.auto_assign on both controllers (if on, the disk will auto assign, to do it manually set the option to off)

2.) swap the disk

3.) check with disk show -n, the replaced disk should be shown as not owned

4.) from the controller, which needs the disk, type: disk assign ........DISKNAME..... or disk assign all (if only 1 disk is unowned)

5.) change options disk.auto_assign back (if changed in Step1)
