520 High availability and load balancing using clusters
Managing clusters
Adding or removing a cluster member
You can add or remove cluster members without using the Cluster Wizard. You must connect the SGMI
computer to a cluster member. When you remove a cluster member, you cannot remove the cluster
member you are logged on to. If there are only two cluster members, removing one of the members
dissolves the cluster. The panels that you see when you use the Modify Cluster option are identical to
the panels that you saw in the Cluster Wizard.
Modify cluster membership
When a member is added or removed from a cluster, the cluster is rebooted and traffic is interrupted.
Prepare for this interruption when planning to modify cluster membership.
