Option 1: Verify ID (HA pair)
Verify the system ID change on an HA system
You must confirm the system ID change when you boot the
replacement
node and
then verify that the change was implemented.
This procedure applies only to systems running ONTAP in an HA pair.
Steps
1. If the replacement node 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 node, boot the node, entering
y
if you are prompted to
override the system ID due to a system ID mismatch.
boot_ontap bye
The node will reboot, if autoboot is set.
3. Wait until the
Waiting for giveback…
message is displayed on the
replacement
node console
and then, from the healthy node, 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
node, 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)
4. From the healthy node, 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.
You can enter the following command to monitor the progress of the savecore command:
system
