• With LPAR manager firmware version 01-6X or later, enabling Save Time
Config is recommended. If you reboot LPAR manager after operating it for
a long time with Save Time Config disabled, or if a system failure in LPAR
manager or failover with N+M cold standby unexpectedly occurs, a time
lag occurs in the guest OS.
• You can change settings for Save Time Config while LPAR manager is
running.
• If changing LPAR manager configuration or LPAR configuration with Save
Time Config enabled, make sure to save LPAR manager configuration at
the end of the setting change. Although LPAR manager configuration is
saved at time adjustment with Save Time Config enabled, the timing
cannot be specified.
• When LPAR manager configuration is saved at time adjustment, LPAR
manager screen appears; system event logs are collected; the alert is
notified. Those operations can be prevented by disabling Save Time
Config.

• Using NTP
– Check LPAR manager system time on the Date and Time screen. If the
LPAR manager system time is not synchronized, adjust the LPAR manager
system time by restoring the NTP server network state.
– Adjust deactivated LPAR time using Adjust LPAR Time for LP System
Time, Specified Zone, and UTC, on the Date and Time screen. For
activated LPARs, adjust the time by using the guest OS or NTP time
synchronization for the guest OS.
– Enable the Save Time Config on the Options screen.
