halt
After you issue the command, wait until the system stops at the LOADER
prompt.
2.
If you have not already done so, on the replacement node, enter the following
command at the LOADER prompt to boot the node, and press
Ctrl-C
to
interrupt the boot process when prompted to display the boot menu:
boot_ontap
If you are prompted to override the system ID due to a system ID mismatch,
enter
y
.
3.
Wait until the
Waiting for giveback...
message is displayed on the
replacement node's console and then, on the healthy node, enter the following
command to verify that the NVRAM adapter replacement has been detected
and that the new partner system ID has been automatically assigned:
cf status
You should see a message similar to the following indicating that the system ID
change has been detected:
HA mode.
System ID changed on partner (Old: 1873774576, New: 1873774574).
partner_node has taken over target_node.
target_node is ready for giveback.
The message shows the new system ID of the replacement node. In this
example it is 1873774574.
4.
From the healthy node, ensure that any coredumps on the replacement node
are saved:
a.
Enter the following command:
partner savecore
b.
If the command output indicates that savecore is in progress, wait for
savecore to complete before issuing the giveback. You can enter the
following command to monitor the progress of the savecore:
partner savecore -s
5.
Enter the following command from the healthy node after the replacement
node is displaying the
Waiting for Giveback
message:
cf giveback
6.
Verify that the disks (or gateway LUNs) were assigned correctly by entering the
following command:
disk show
Make sure that the disks belonging to the replacement node show the new
system ID for the replacement node. In the following example, the disks owned
by node2 now show the new system ID, 1873774574:
system-1> disk show
