d. Check other cabling by clicking the appropriate tab, and then examining the output from Config Advisor.
Step 2: Reassign disks
If the storage system is in an HA pair, the system ID of the new controller module is automatically assigned to
the disks when the giveback occurs at the end of the procedure. In a stand-alone system, you must manually
reassign the ID to the disks.
You must use the correct procedure for your configuration.
Option 1: Verify the system ID change on an HA system
You must confirm the system ID change when you boot the replacement controller and then verify that the
change was implemented.
This procedure applies only to systems running ONTAP in an HA pair.
1.
If the replacement controller is in Maintenance mode (showing the
*> prompt, exit Maintenance mode and
go to the LOADER prompt:
halt
2.
From the LOADER prompt on the replacement controller, boot the controller, entering
y if you are prompted
to override the system ID due to a system ID mismatch:
boot_ontap
3.
Wait until the
Waiting for giveback… message is displayed on the replacement controller console and
then, from the healthy controller, verify that the new partner system ID has been automatically assigned:
storage failover show
In the command output, you should see a message that the system ID has changed on the impaired
controller, showing the correct old and new IDs. In the following example, node2 has undergone
replacement and has a new system ID of 151759706.
node1> `storage failover show`
Ê Takeover
Node Partner Possible State Description
------------ ------------ --------

node1 node2 false System ID changed on
partner (Old:
Ê 151759755, New:

node2 node1 - Waiting for giveback
(HA mailboxes)
4. From the healthy controller, verify that any coredumps are saved:
a.
Change to the advanced privilege level:
set -privilege advanced
You can respond Y when prompted to continue into advanced mode. The advanced mode prompt
appears (*>).
b.
Save any coredumps:
system node run -node local-node-name partner savecore
c. Wait for the `savecore`command to complete before issuing the giveback.
