2.3.1.5 NTP server
The MU of the SE server is configured as an NTP server and is used as the central NTP
server for the SE server.
The units SU x86 and HNC are configured in such a manner that time synchronization takes
place from the local SE server's MU.
In the case of MU redundancy, both MUs of the local SE server are configured as timers.
If external timers are used in a multi-MU configuration, the same external NTP servers must
be configured on each MU, so that the time remains accurate even if one MU is switched
off.
The static IPv6 address of the MU can be used for time synchronization of an AU with the
local SE server's MU.
For further details, see section “Time synchronization” on page 65.
2.3.2 Integration of BS2000 into the SE Manager
The VM Management for SU /390 in VM2000 operation mode requires communication
between the monitor system and the MU. The BS2000 Backup Monitor also requires
communication between the BS2000 systems on which the backup requests take place and
the MU.
The communication uses the internal network MCNPR (see figure 2 on page 33) and must
be configured as follows:
● In the BS2000 systems mentioned a suitable BCAM configuration must be configured
by means of the templates provided. See also the BCAM manual [13].
● The REWAS subsystem must be active (default).
