Removing a hot spare disk

Removing a hot spare disk requires you to remove ownership information from the disk. This prevents the disk from causing problems when it is inserted into another node, and notifies Data ONTAP that you are removing the disk, which prevents unwanted AutoSupport messages.

About this task

Removing a hot spare disk does not make the contents of that disk inaccessible. If you need absolute assurance that the data contained by this disk is irretrievable, you should sanitize the disk instead of completing this procedure.

Steps

  1. Find the disk name of the hot spare disk you want to remove: storage aggregate show-spare-disks
  2. Determine the physical location of the disk you want to remove: storage disk set-led -disk disk_name
    The fault LED on the face of the disk is lit.
  3. If disk ownership automatic assignment is on, turn it off: storage disk option modify -node node_name -autoassign off
  4. If disk ownership automatic assignment is on for the node's HA partner, turn it off on the partner node also.
  5. Remove the software ownership information from the disk: storage disk removeowner disk_name
  6. Remove the disk from the disk shelf, following the instructions in the hardware guide for your disk shelf model.
  7. If you turned off disk ownership automatic assignment previously, turn it on now: storage disk option modify -node node_name -autoassign on
  8. If you turned off disk ownership automatic assignment previously on the node's HA partner, turn it on for the partner node also.
