A cluster must have either IPv4 addresses or IPv6 addresses that are assigned, or it can have both. If the addresses are assigned, you can use the IPv4 addresses to access the cluster from the command-line tools or the SAN Volume Controller Console.
This field contains the existing IPv4 addresses of the cluster. If this SAN Volume Controller node is not a member of a cluster or IPv4 addresses have not been assigned, this field is blank.
