Modifying assignment of spare disks or array LUNs

You can change the ownership of a spare disk or array LUN to another storage system.

Before you begin

A disk or array LUN that is a spare has been assigned to a specific system, but it has not yet been added to an aggregate. If the disk or array LUN whose ownership you want to change is in an aggregate, you must do the following before you can change ownership of the disk or array LUN:

About this task

You can change ownership of disks only between nodes in an HA pair. You can change ownership of array LUNs among the systems in a V-Series neighborhood.

Steps

  1. At the console of the storage system that owns the disk or array LUN that you want to reassign, enter the following to see a list of spare disks or spare array LUNs on the system: aggr status -s
  2. On the system that owns the spare disk or array LUN you want to reassign, enter either of the following commands to reassign ownership of the disk or array LUN: disk assign LUN-or-disk-name -o new_owner_name -f or disk assign LUN-or-disk-name -s sysID-of-receiving_system -f
    -o is the name of the system that you want to be the new owner of the disk or array LUN.
    -s is the ID of the system that you want to be the new owner of the disk or array LUN. You can obtain the system ID of the destination system by running sysconfig on the destination system.
    -f is required to force the change.
  3. Enter the following command to verify that the ownership of the spare disk or array LUN moved to the other system: aggr status -s
    The spare disk or array LUN that you moved should no longer appear in the list of spares.
  4. On the destination system, enter the following command to verify that the spare disk or spare array LUN whose ownership you changed is listed as a spare owned by the destination system: aggr status -s

After you finish

If you changed ownership for array LUNs, you should verify that two paths exist for each array LUN and verify path failover to ensure that you have path redundancy. You must add the disk or array LUN to an aggregate before you can use it for storage.
