Hitachi Global Link Manager Software Installation and Configuration Guide

products are already installed. This section also describes how to change the
time, if necessary, after installing Global Link Manager.
Note: If the machine time is changed while Hitachi Command Suite Common
Component is running, Hitachi Command Suite products including Global Link
Manager might not operate correctly. We recommend that you change the
machine time before installing Global Link Manager.
Settings required when using the time adjustment function
If you use a function that automatically adjusts the time, such as NTP, make
sure that the function gradually adjusts the machine time (in a machine that
is running faster than the actual time), rather than adjusting the time all at
once. Some functions gradually adjust the time for time differences that are
within a predefined time, but some other functions adjust the time all at once
for time differences that exceed the predefined time. Set the frequency at
which the function adjusts the time to ensure that time differences stay
within the predefined time required by the function to adjust the time
gradually.
For example, the Windows Time service adjusts the machine time gradually
rather than adjusting it all at once, when the machine time is running faster
than the actual time by no more than the predefined time. After you check
the range of time differences that the Windows Time service adjusts
gradually, you can set the frequency of the Windows Time service's time
adjustments so that differences between machine time and actual time are
never outside this range.
When the time adjustment function is unavailable or when you need
to change the time immediately
To change the machine time when you cannot use a function that
automatically adjusts the time or when you need to change the time
immediately:
1. Execute the following command to stop Hitachi Command Suite Common
Component:
Hitachi-Command-Suite-Common-Component-installation-folder\bin
\hcmds64srv /stop
If other Hitachi Command Suite products have been installed on the same
machine, the services of these Hitachi Command Suite products are also
stopped.
2. Change the machine time.
3. Restart the machine.
