Set Secondary CC-SG Node
1. Click Discover CommandCenters to scan and display all CC-SG appliances on the same
subset as your one you are currently using. Alternatively, you can add a CC-SG, perhaps
from a different subnet, by specifying an IP address in CommandCenter address in the
bottom of the window. Click Add CommandCenter.
Note: Adding a backup CC-SG from a different subnet or network may avoid issues affecting a
single network or physical location.
2. To add a Secondary Node, or backup CC-SG node, select a CC-SG unit with Standalone
status from the Cluster Configuration table. The version number must match the primary
node’s version.
3. Type a valid user name and password for the backup node in the Backup username and
Password fields.
4. Click Join “Backup” Node.
5. A confirmation message will appear. Click Yes to assign Secondary status to the selected
node, or click No to cancel.
Important! Once you begin the Join process, do not perform any other
functions in CC-SG until the Join process has completed as indicated in step 6,
below.
6. After you click Yes, CC-SG will restart the newly selected Secondary node. This process can
take several minutes. When restart is complete, a confirmation message appears on your
screen.
7. On the Administration menu, click Cluster Configuration to view the updated Cluster
Configuration table.
Note: If the Primary and Secondary Nodes lose communication with one another, the Secondary
Node will assume the role of the Primary Node. When connectivity resumes, you may have two
Primary Nodes. You should then remove a Primary Node and reset it as a Secondary Node.
Remove Secondary CC-SG Node
1. To remove Secondary Node status from a CC-SG unit and reassign it to a different unit in
your configuration, select the Secondary CC-SG Node in the Cluster Configuration table, and
then click Remove “Backup” Node.
2. When the confirmation message appears, click Yes to remove Secondary Node status, or
click No to cancel.
Note: Clicking Remove “Backup” Node removes the designation of Secondary Node. It does not
delete the Secondary CC-SG unit from your configuration.
Remove Primary CC-SG Node
1. To remove Primary Node status from a CC-SG unit and reassign it to another unit in your
configuration, select the Primary CC-SG Node in the Cluster Configuration table, and then
click Remove Cluster.
2. When the confirmation message appears, click Yes to remove Primary Node status, or click
No to cancel.
Note: Clicking Remove Cluster does not delete the Primary CC-SG unit from your configuration;
it simply removes the designation of Primary Node. Remove Cluster is only available when no
backup nodes exist.
