Removing one array LUN from use by Data ONTAP

If the storage array administrator no longer wants to use a particular array LUN for Data ONTAP, you must remove the information that Data ONTAP wrote to the LUN (for example, size and ownership) before the administrator can reconfigure the LUN for use by another host.

Before you begin

If the LUN that the storage array administrator no longer wants Data ONTAP to use is in an aggregate, you must take the aggregate to which the LUN belongs offline and destroy the aggregate before starting this procedure. Taking an aggregate offline and destroying it changes the LUN from a data LUN to a spare LUN.


  1. Enter the following command: disk remove -w LUNfullname
    LUNfullname is the full name of the array LUN.
