6.1.2 Setting the XSCF Time Before System Startup


6.1.2 Setting the XSCF Time Before System Startup
This section describes the procedure for setting the XSCF time before physical partition startup so that logical domains start with the correct time.
  1. Where the NTP client function is disabled
    At initial system installation, use the setdate(8) command to set the XSCF time before starting the physical partition.
    After the initial installation, even if there is a time deviation from the XSCF before you start the physical partition, it will not affect the logical domain time.
    Therefore, you do not need to set the XSCF time when starting the physical partition.
  1. Where the NTP client function is enabled
    There may be a time deviation from the XSCF because time synchronization failed between the NTP server and the XSCF when the XSCF started. (Note)
    If the physical partition starts in this state, the logical domain time may shift.
    Perform the following procedure to set the XSCF time, and then start the physical partition.
Note - For example, if the LAN between the NTP server and the XSCF was disconnected when the XSCF started, the XSCF time may shift even though the XSCF is now connected to the LAN.
  1. Check the current XSCF time.
    If the XSCF time is correct, step 2 and later are unnecessary.

  1. Correct the XSCF time.
  1. Check the network environment and the NTP server status.
  1. Reboot the XSCF.
XSCF> rebootxscf -a
  1. After the XSCF reboot, check the current XSCF time.
