IMPORTANT: Avoid deploying an IPv6-only configuration until the availability of IPv6-only support for the iLOs.

oImport remote enclosures using IPv6 addresses because IPv4 addresses would not exist in an IPv6-only environment.

oImporting an enclosure with dual configuration fails because it is mandatory to have a uniform IP configuration on all enclosures of the domain.

Migration from a dual configuration to IPv6-only configuration:

1.Ensure the new configuration is not IPv6-only until the availability of IPv6-only support for iLO.

2.Validate if accessing VCM via IPv6 addresses is possible by either ssh or via the web GUI.

3.Disable DHCPv4 server, if any, in the environment.

4.Remove IPv4 addresses from the interconnect EBIPA configuration tabs.

5.Remove IPv4 configurations in the various utilities if they are not wanted in the future.

IPv4 configuration continue to exist and do not interfere with the operations. These configurations include RSYSLOG entries, SNMP trap receiver entries, VCM Domain static IPv4 address, LDAP and RADIUS/TACACS IPv4 entries.

6.Wait for the IPv4 addresses to be cleared from OA and VC. A reboot is recommended if the lease period of a DHCPv4 address is high to ensure faster IP mode change.

7.Ensure the OA does not have an IPv4 address configured.

8.If "Enclosure IP Mode" is configured, either through the OA CLI or OA GUI, ensure that the OA does not have an IPv4 address configured.

To migrate from an IPv4 to IPv6-only configuration, HP recommends migrating to a dual configuration, and then migrating to an IPv6-only configuration.
