- Reconnect the Ethernet cables and the Fibre Channel cables to the node.
- Once the initial configuration is complete and all cables are reconnected, add the configured node to the HA setup as follows:
On the node that is in the HA setup, log on to the NetBackup Appliance Shell Menu as
Go to Main > Manage > HighAvailability.
Add the configured node to the HA setup with the following command:
Where hostname is the short host name or the fully qualified domain name (FQDN) of the configured node.
When the following message appears, make sure that you checked the SSH ECDSA fingerprint directly on the partner node:
Do the fingerprint values match? [yes, no] (no)
To make sure that the network is safe, you need to confirm that the SSH ECDSA fingerprint of the partner node is correct. For the instructions on how to check the identity of the appliance, refer to the NetBackup Appliance Command Reference Guide.
If the values match, enter yes.
After the pre-check has passed, when the following message appears, enter a reissue token to trust the host ID-based certificate:
Reissue token is mandatory. Enter the reissue token for the required host to obtain a host-ID based certificate:
For more information about security certificates, refer to the chapter Security certificates in NetBackup in the NetBackup Security and Encryption Guide.
