You can perform maintenance operations on the VSA cluster, such as placing the entire cluster or just a single VSA cluster member in the maintenance mode, replacing a VSA cluster member that is offline, and changing the VSA cluster IP address. Using Multiple VSA ClustersYou can create multiple VSA clusters and manage them using one centrally located vCenter Server. Perform Maintenance Tasks on the Entire VSA ClusterYou can put the VSA cluster in maintenance mode to perform maintenance tasks on any of its components (hosts, datastores, networking, and so on). Perform Maintenance Tasks on a VSA Cluster MemberYou can put a VSA cluster member in maintenance mode and perform maintenance tasks on the host that accommodates the member. Replace a VSA Cluster MemberUse the Replace VSA Cluster Member wizard to replace an ESXi host that failed or underwent storage configuration changes. Replace a Cluster Member of a Legacy VSA ClusterUse this procedure if you need to replace a member of a legacy cluster after you have already upgraded VSA Manager to version 5.5 or later. Change the VSA Cluster IP AddressThe VSA cluster IP address belongs to the VSA cluster member that is elected to be the leader of the VSA cluster. If another member is elected as the leader, the VSA cluster IP address is assigned to the new leader member. You can change the IP address after you install the VSA cluster. Change the VSA Cluster PasswordYou can change the default VSA cluster password. Adding Storage Capacity to VSA ClustersIf any unused storage capacity remains on ESXi cluster members, you can expand an existing VSA cluster when it needs more storage space. You can also expand the VSA cluster after you increase physical storage capacity on the cluster members. Moving a VSA ClusterYou can move a VSA cluster from one location to another. Reconfigure the VSA Cluster NetworkRun the Reconfigure VSA Cluster Network wizard to change network settings of the VSA cluster. Indicate Changes to Virtual Machine ConfigurationDuring the reconfiguration of the VSA cluster network, the VSA datastores change IP addresses and the virtual machines running on them must be reregistered. You can indicate that the virtual machines were moved after the reconfiguration process completes.
