HP Onboard Administrator - Manual (Page 111)

Configuring the HP BladeSystem c7000 enclosure and enclosure devices 111
Replace the Standby Onboard Administrator only while the enclosure is powered on to ensure that the
Enclosure IP Mode settings are not changed.
NOTE: This feature is disabled while in the FIPS mode ON/DEBUG.
NOTE: Enabling Enclosure IP mode on either the IPv4 Settings tab or the IPv6 Settings tab
automatically enables this mode on both tabs.
Enclosure Network Settings
IPv6 supports multiple addresses. You can enable any combination of the network settings. With IPv6,
SLAAC and/or DHCPv6 enabled, the Onboard Administrator can obtain IP addresses from all the selected
sources. It can have both automatically assigned IP addresses and user-specified static IP addresses. The
Enable SLAAC and Enable DHCPv6 settings take effect only if IPv6 is enabled.
• Enable IPv6—Enables IPv6 protocol for all Onboard Administrator, interconnect, and server iLO
modules in the enclosure. When enabled, one link-local address is auto configured.
• Enable SLAAC—Enables IPv6 Stateless address autoconfiguration messages to all Onboard
Administrator, interconnect, and server iLO modules in the enclosure. This feature affects only global
IPv6 addresses. When IPv6 and SLAAC are both enabled, the Onboard Administrator can obtain up to
11 SLAAC IP addresses.
• Enable DHCPv6—Enables the active (and standby, if configured) Onboard Administrator to request a
DHCPv6 IP address. Allows DHCPv6 traffic on the enclosure management network.
CAUTION: If you disable IPv6 in an IPv6-only environment, you will lose your connection to the
Onboard Administrator GUI and any SSH sessions. To reestablish your connection, you must
perform the initial enclosure configuration via IPv4 networking, the Insight Display, or the
Onboard Administrator serial console interface. When disabling IPv6, SLAAC, or DHCPv6, all
connections that depend on the disabled protocol are closed. For example, if you are connected
to the Onboard Administrator using its DHCPv6-assigned address, disabling the enclosure
DHCPv6 setting results in your session being closed.
NOTE: For SLAAC addresses to be successfully configured, the Enable SLAAC setting must be
enabled on the enclosure. In addition, an IPv6 router must be configured on the enclosure
management network to provide the SLAAC addresses via Router Advertisements. iLOs may need
to be configured separately to obtain SLAAC addresses. Both the Enable SLAAC and Enable IPv6
settings must be enabled to allow the necessary traffic on the enclosure management network.
NOTE: For DHCPv6 addresses to be successfully configured, the Enable IPv6 enclosure setting
must be enabled and a DHCPv6 server configured on the management network. iLOs and
interconnects must be configured separately to request a DHCPv6 address. If they are configured
to request DHCPv6 addresses, the Enable IPv6 and Enable DHCPv6 settings must be enabled to
allow the necessary traffic on the enclosure management network.
NOTE: After a factory reset, the enclosure IPv6 network settings (IPv6, SLAAC, and DHCPv6) are
enabled by default.
Active Onboard Administrator Network Settings
The Onboard Administrator can have up to three static IP addresses.
