HP OneView manual About enclosure groups, Effects of managing an enclosure

NOTE: HP does not recommend using iLO or the OA to make changes to a device. Making changes to a device from its iLO or OA could cause it to become out of synchronization with the appliance.

You can manually refresh the connection between the appliance and an enclosure from the Enclosures screen. Refreshing an enclosure will refresh all devices in it. See the online help for the Enclosures screen to learn more.

17.5 About enclosure groups

An enclosure group is a logical resource that defines a set of enclosures that use the same configuration for network connectivity. The network connectivity for an enclosure group is defined by the logical interconnect group associated with the enclosure group. This ensures that each enclosure has an identically configured logical interconnect and the same configuration for network connectivity.

17.6 Effects of managing an enclosure

When an enclosure is being managed by the appliance, the following enclosure settings are in effect:

•A management account is created.

•SNMP is enabled and the appliance is added as an SNMP trap destination.

•NTP (Network Time Protocol) is enabled and the appliance becomes the NTP time source.

•The NTP default polling interval is set to 8 hours.

•An appliance certificate is installed to enable single sign-on operations.

•Enclosure firmware management is disabled.

•The OA firmware is updated to minimum firmware levels, listed in the HP OneView Support Matrix.

•The server hardware iLO time zone is set to Atlantic/Reykjavik as recommended in the iLO documentation.

The time zone setting determines how the server hardware iLO adjusts UTC (Coordinated Universal Time) time to obtain the local time, and how it adjusts for daylight saving time (summer time). For the entries in the iLO event log and IML to display the correct local time, you must specify the time zone in which the server is located.

If you want iLO to use the time provided by the NTP server, without adjustment, configure the iLO to use a time zone that does not apply an adjustment to UTC time. In addition, that time zone must not apply a daylight saving time (summer time) adjustment.

There are several time zones that meet this requirement. One example is the Atlantic/Reykjavik time zone. This time zone is neither east nor west of the prime meridian and time does not change in the spring or fall.
