CHAPTER 7 Work after Installation
FIGURE 7.2 Operation with external NTP servers (three NTP servers)
Only a single NTP server can be specified for a client. In this case, if the NTP client is no longer able to communicate
with the specified server, NTP server communication is lost because no other synchronized server is available.
Time correction via NTP is disabled during the time taken for recovery of communication between the NTP client
and NTP server. Time is measured based on system clock precision. Since system clock precision varies with the
system, in cases where the time is not corrected via NTP, middleware, or application problems may occur due to
an increasing time difference between systems.
Remarks
NTP servers 1 to 3 provide highly precise time over the Internet or intranet.
7.2.2

Setting an NTP server

Set another NTP server for time synchronization using the NTP client function of the MMB.
Note
The MMB time and the partition time are managedseparately by independent clocks.
The MMB clock does not report or adjust the partitiontime. Keep the MMB time and the partition time the same,
or at least close, becausethey are needed for the following cases:
- When checking the MMB log against the OS log in a partition at the hardware failure time
- When conducting a system audit or security audit
