Recable the system and reassign disks - AFF A200
Continue the replacement procedure by re-cabling the storage and confirming disk reassignment.
Step 1: Re-cable the system
Recable the controller module's storage and network connections.
-
Recable the the controller module to storage and network conntections.
-
Verify that the cabling is correct by using Active IQ Config Advisor.
-
Download and install Config Advisor.
-
Enter the information for the target system, and then click Collect Data.
-
Click the Cabling tab, and then examine the output. Make sure that all disk shelves are displayed and all disks appear in the output, correcting any cabling issues you find.
-
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.
-
If the replacement controller is in Maintenance mode (showing the
*>
prompt, exit Maintenance mode and go to the LOADER prompt:halt
-
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
-
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` Takeover Node Partner Possible State Description ------------ ------------ -------- ------------------------------------- node1 node2 false System ID changed on partner (Old: 151759755, New: 151759706), In takeover node2 node1 - Waiting for giveback (HA mailboxes)
-
From the healthy controller, verify that any coredumps are saved:
-
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 (*>). -
Save any coredumps:
system node run -node local-node-name partner savecore
-
Wait for the `savecore`command to complete before issuing the giveback.
You can enter the following command to monitor the progress of the savecore command:
system node run -node local-node-name partner savecore -s
-
Return to the admin privilege level:
set -privilege admin
-
-
If your storage system has Storage or Volume Encryption configured, you must restore Storage or Volume Encryption functionality by using one of the following procedures, depending on whether you are using onboard or external key management:
-
Give back the controller:
-
From the healthy controller, give back the replaced controller's storage:
storage failover giveback -ofnode replacement_node_name
The replacement controller takes back its storage and completes booting.
If you are prompted to override the system ID due to a system ID mismatch, you should enter
y
.If the giveback is vetoed, you can consider overriding the vetoes. -
After the giveback has been completed, confirm that the HA pair is healthy and that takeover is possible:
storage failover show
The output from the
storage failover show
command should not include the System ID changed on partner message.
-
-
Verify that the disks were assigned correctly:
storage disk show -ownership
The disks belonging to the replacement controller should show the new system ID. In the following example, the disks owned by node1 now show the new system ID, 1873775277:
node1> `storage disk show -ownership` Disk Aggregate Home Owner DR Home Home ID Owner ID DR Home ID Reserver Pool ----- ------ ----- ------ -------- ------- ------- ------- --------- --- 1.0.0 aggr0_1 node1 node1 - 1873775277 1873775277 - 1873775277 Pool0 1.0.1 aggr0_1 node1 node1 1873775277 1873775277 - 1873775277 Pool0 . . .
-
Verify that the expected volumes are present for each controller:
vol show -node node-name
-
If you disabled automatic takeover on reboot, enable it from the healthy controller:
storage failover modify -node replacement-node-name -onreboot true
Option 2: Manually reassign the system ID on a stand-alone system in ONTAP
In a stand-alone system, you must manually reassign disks to the new controller's system ID before you return the system to normal operating condition.
About this task
This procedure applies only to systems that are in a stand-alone configuration.

-
If you have not already done so, reboot the replacement node, interrupt the boot process by pressing Ctrl-C, and then select the option to boot to Maintenance mode from the displayed menu.
-
You must enter
Y
when prompted to override the system ID due to a system ID mismatch. -
View the system IDs:
disk show -a
-
You should make a note of the old system ID, which is displayed as part of the disk owner column.
The following example shows the old system ID of 118073209:
*> disk show -a Local System ID: 118065481 DISK OWNER POOL SERIAL NUMBER HOME -------- ------------- ----- ------------- ------------- disk_name system-1 (118073209) Pool0 J8XJE9LC system-1 (118073209) disk_name system-1 (118073209) Pool0 J8Y478RC system-1 (118073209) . . .
-
Reassign disk ownership by using the system ID information obtained from the disk show command:
disk reassign -s old system ID disk reassign -s 118073209
-
Verify that the disks were assigned correctly:
disk show -a
The disks belonging to the replacement node should show the new system ID. The following example now show the disks owned by system-1 the new system ID, 118065481:
*> disk show -a Local System ID: 118065481 DISK OWNER POOL SERIAL NUMBER HOME -------- ------------- ----- ------------- ------------- disk_name system-1 (118065481) Pool0 J8Y0TDZC system-1 (118065481) disk_name system-1 (118065481) Pool0 J8Y0TDZC system-1 (118065481) . . .

If your storage system has Storage or Volume Encryption configured, you must restore Storage or Volume Encryption functionality by using one of the following procedures, depending on whether you are using onboard or external key management:
-
Boot the node:
