Steps
1. Recable the system.
2. Verify that the cabling is correct by using
Active IQ Config Advisor.
a. Download and install Config Advisor.
b. Enter the information for the target system, and then click Collect Data.
c. 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.
d. Check other cabling by clicking the appropriate tab, and then examining the output from Config Advisor.
Step 2: Verifying the system ID change on an HA system
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. 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.
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:
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

4. From the healthy node, verify that any coredumps are saved:
