11.3.3 Interpreting SP Clock Settings
When the service processor reboots, the SP clock is set to Thu Jan 1 00:00:00 UTC
1970. The SP reboots as a result of the following:
■ A complete system unplug/replug power cycle
■ An IPMI command; for example, mc reset cold
■ A command-line interface (CLI) command; for example, reset /SP
■ ILOM web GUI operation; for example, from the Maintenance tab, select Reset SP
■ An SP firmware upgrade
After an SP reboot, the SP clock is changed by the following:
■ When the host is booted - The host’s BIOS unconditionally sets the SP time to
that indicated by the host’s RTC. The host’s RTC is set by the following
operations:
■
When the host’s CMOS is cleared as a result of changing the host’s RTC battery
or inserting the CMOS-clear jumper on the motherboard. The host’s RTC starts
at Jan 1 00:01:00 2002.
■
When the host’s operating system sets the host’s RTC. The BIOS does not
consider time zones. Solaris and Linux software respect time zones and will set
the system clock to UTC. Therefore, after the OS adjusts the RTC, the time set
by the BIOS will be UTC. Micorsoft Windows software does not respect time
zones and sets the system clock to local time. Therefore, after the OS adjusts
the RTC, the time set by the BIOS will be local time.
■
When the user sets the RTC using the host BIOS Setup screen.
■ Continuously via NTP if NTP is enabled on the SP - NTP jumping is enabled to
recover quickly from an erroneous update from the BIOS or user. NTP servers
provide UTC time. Therefore, if NTP is enabled on the SP, the SP clock will be in
UTC.
■ Via the CLI, ILOM web GUI, and IPMI
11.4 How to Configure Network Settings
This section explains how to configure the network parameters for the ILOM Service
Processor.
The service processor (SP) automatically configures its IP settings using the Dynamic
Host Configuration Protocol (DHCP). If your network does not support this
protocol, you need to set the parameters manually.
