HP Virtual Connect 8Gb 20-port Fibre Channel Module for c-Class BladeSystem - Manual (Page 304)

Appendix C: Using IPv6 with Virtual Connect 304
IMPORTANT: Avoid deploying an IPv6-only configuration until the availability of IPv6-only
support for the iLOs.
o Import remote enclosures using IPv6 addresses because IPv4 addresses would not exist in an
IPv6-only environment.
o Importing an enclosure with dual configuration fails because it is mandatory to have a uniform IP
configuration on all enclosures of the domain.
Migrations
Migration from IPv4 to a dual configuration
VC version OA version <4.01 OA version 4.01 or higher
VC version <4.10 • Install SPP 2013.09.0 (B) or later,
which contains the required VC
and OA versions.
• Enable IPv6 on all OAs starting
with the local enclosure.
• Enable DCPv6 or RA-SLAAC or
both to enable global addressing.
• Install SPP 2013.09.0 (B) or later,
which contains the required VC and
OA versions, if not already installed.
• Upgrade VC to 4.10 or higher.
• Enable IPv6 on all OAs starting with
the local enclosure, if not already
done.
• Enable DHCPv6 or RA-SLAAC or
both to enable global addressing.
VC version 4.10 or higher • Install SPP 2013.09.0 (B) or later,
if not already installed. The SPP
contains the required OA version.
• Enable IPv6 on all OAs starting
with the local enclosure.
• Enable DHCPv6 or RA-SLAAC or
both to enable global addressing.
• Install SPP 2013.09.0 (B) or later,
which contains the required OA
version, if not already installed.
• Enable IPv6 on all OAs starting with
the local enclosure.
• Enable DHCPv6 or RA-SLAAC or
both to enable global addressing.
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.
