The system boots to Waiting for giveback… prompt.
8. Move the console cable to the partner controller and login as "admin".

Confirm the target controller is ready for giveback with the
storage failover show command.
10.
Giveback only the CFO aggregates with the
storage failover giveback -fromnode local
-only-cfo-aggregates true

◦ If the command fails because of a failed disk, physically disengage the failed disk, but leave the
disk in the slot until a replacement is received.
◦ If the command fails because of an open CIFS sessions, check with customer how to close out
CIFS sessions.
Terminating CIFS can cause loss of data.
◦ If the command fails because the partner "not ready", wait 5 minutes for the NVMEMs to
synchronize.
◦ If the command fails because of an NDMP, SnapMirror, or SnapVault process, disable the
process. See the appropriate Documentation Center for more information.

storage failover
show
and `storage failover show-giveback` commands.
Only the CFO aggregates (root aggregate and CFO style data aggregates) will be shown.

c.
Enter the
security key-manager key query command to see a detailed view of all keys

Restored column = yes/true for all
authentication keys.
If the Restored column = anything other than yes/true, contact Customer
Support.
d. Wait 10 minutes for the key to synchronize across the cluster.
13. Move the console cable to the partner controller.
14.
Give back the target controller using the
storage failover giveback -fromnode local

15.
Check the giveback status, 3 minutes after it reports complete, using the
storage failover show
command.
If giveback is not complete after 20 minutes, contact Customer Support.

At the clustershell prompt, enter the
net int show -is-home false command to list the logical
