A virtual IP is assigned which is used for communications between the MDM cluster and the SDCs. Only one

virtual IP address is mapped to each NIC, with a maximum of four virtual IPs per system. This virtual IP is

mapped to the manager MDM dynamically and is moved if the primary MDM is under maintenance.

Once the summary screen displays, the deployment begins. If errors are encountered, the installation wizard

will halt and resume once the issue is resolved.

6.3.1

MDM Virtual IP Addresses

Up to four virtual IP addresses can be defined for the MDM cluster and are highly recommended. SDCs are

then mapped to the MDM cluster's virtual IP addresses, instead of to static MDM IP addresses. MDMs are

sometimes switched during normal operation of the cluster, and the virtual IP address will always be mapped

to the active MDM.

The use of virtual IP addresses simplifies maintenance procedures on the MDM cluster, because system

components communicate via the virtual IP addresses. Therefore, SDCs do not need to be reconfigured when

a server hosting an MDM is replaced.

In new installations in Linux environments, the MDM cluster's virtual IP address can be added and mapped

using the VxFlex OS Installer CSV file. In VMware environments, virtual IP addresses are mandatory, and

configuration is performed using the VxFlex OS VMware Installation Wizard, in the Configure SVM stage. The
