Ilo Clock Synchronization; Dhcp Ntp Address Selection; Ilo Nic Auto-Selection - HP HPE iLO 5 User Manual

Secondary Time Server
Configures iLO to use a secondary time server with the specified address. You can enter the server
address by using the server FQDN, IPv4 address, or IPv6 address.
Time Zone
Determines how iLO adjusts UTC time to obtain the local time, and how it adjusts for Daylight Savings
Time (Summer Time). In order for the entries in the iLO Event Log and IML to display the correct local
time, you must specify the server location time zone, and select Show Local Time in the iLO Event
Log and IML display filters.
If you want iLO to use the time the SNTP server provides, without adjustment, select a time zone that
does not apply an adjustment to UTC time. In addition, that time zone must not apply a Daylight
Savings Time (Summer Time) adjustment. There are several time zones that fit this requirement. One
example that you can select in iLO is Greenwich (GMT). If you select this time zone, the iLO web
interface pages and log entries display the exact time provided by the SNTP server.
NOTE:
Configure the NTP servers to use Coordinated Universal Time (UTC).

iLO clock synchronization

SNTP allows iLO to synchronize its clock with an external time source. Configuring SNTP is optional
because the iLO date and time can also be synchronized from the following sources:
• System ROM (during POST only)
• Onboard Administrator (ProLiant server blades only)
• Frame Link Module (Synergy compute modules)
Primary and secondary NTP server addresses can be configured manually or through DHCP servers. If
the primary server address cannot be contacted, the secondary address is used.

DHCP NTP address selection

When you use DHCP servers to provide NTP server addresses, the iLO Client Applications use IPv6
first setting on the IPv6 page controls the selection of the primary and secondary NTP values. When iLO
Client Applications use IPv6 first is selected, a DHCPv6-provided NTP service address (if available) is
used for the primary time server and a DHCPv4-provided address (if available) is used for the secondary
time server.
To change the protocol-based priority behavior to use DHCPv4 first, clear the iLO Client Applications
use IPv6 first check box.
If a DHCPv6 address is not available for the primary or secondary address, a DHCPv4 address (if
available) is used.

iLO NIC auto-selection

iLO NIC auto-selection enables iLO to choose between the iLO Dedicated Network Port and the iLO
Shared Network port. At startup, iLO searches for network activity on the available ports, and
automatically selects one for use based on network activity.
This feature enables you to use a common preconfiguration for your ProLiant Gen10 servers. For
example, if you have several servers, some might be installed in a data center where iLO is contacted
through the iLO Dedicated Network Port. Other servers might be installed in a data center where iLO is
