If you have an HA pair, you can enter the applicable command at the console of either
controller.
If your system is operating in.... Then...
7-Mode
Enter the following command:
options disk.auto_assign
Clustered ONTAP
Enter the following command:
storage disk option modify -autoassign
If disk autoassignment is enabled, the output shows
disk.auto_assign on
.
4. If your system does not have disk autoassignment enabled or disk drives in the same stack are
owned by both controllers, assign disk drive ownership.
The following substeps enable you to complete basic disk ownership assignment for 7-Mode.
To specify the disk drives to be assigned or the system to own the disk drives, see the
Data
ONTAP Storage Management Guide for 7-Mode. For 7-Mode HA pairs, you can run these
commands from the system console of either node.
For clustered systems, see the
Clustered Data ONTAP Physical Storage Management Guide for
disk drive ownership information on the NetApp Support Site at
a. Enter the following command to see all the unassigned disk drives:
disk show -n
The disk drives in the hot-added shelf have the ownership state of
Not Owned
.
b. Enter the following command to assign ownership of the disk drives:
disk assign all
If you need to assign the disk drives to a non-local storage system, you can specify that
storage system by using the
-o owner_name
option. To determine the
owner_name
, you
can run the
hostname
command at the console of either controller.
c. Enter the following command to verify the assignments that you made:
disk show -v
5. If you are currently using the ACP capability or want to start using it, complete the following
substeps; otherwise, go to the next step.
If you are cabling a disk shelf...
Then...
To an existing stack of disk
shelves
a. Disconnect any intrastack, stack-to-stack, and controller-to-shelf ACP
connections from the last disk shelf and reconnect them to the same ACP
ports in the new disk shelf.
b. Daisy-chain the ACP ports from the last disk shelf to the new disk shelf.
To an existing SAS HBA or
onboard SAS port
Cable the ACP connections for the new disk shelf by using the ACP cabling
procedure in the
Universal SAS and ACP Cabling Guide on the NetApp Support
Site at
.
Not currently using ACP, but
want to start using it
Cable the ACP connections for your storage system by using the ACP cabling
procedure in the
Universal SAS and ACP Cabling Guide on the NetApp Support
Site at
.
6. Verify that all cables are securely fastened.
7. If you hot-added a disk shelf with SAS optical cables to a stack of disk shelves connected with
SAS copper cables, replace the SAS copper cables for the rest of the shelf-to-shelf connections
