Synchronizing the time-of-day clocks

This optional procedure provides step-by-step instructions that explain how to synchronize the time-of-day clocks for the source and destination Virtual I/O Server logical partitions.

Before you begin
To synchronize the time-of-day clocks, you must be a super administrator.
About this task

Synchronizing the time-of-day clocks for the source and destination Virtual I/O Server logical partitions is an optional step for active partition mobility. You can synchronize the time of day clocks on the mover service partitions using an external time reference such as the network time protocol (NTP). If you choose not to complete this step, the source and destination servers will synchronize the clocks while the mobile partition is moving from the source server to the destination server. Completing this step before the mobile partition is moved can prevent possible errors.

To synchronize the time-of-day clocks on the source and destination Virtual I/O Servers using the HMC, complete the following steps:

  1. In the navigation area, open Systems Management and select Servers.
  2. Select the managed server of your choice in the navigation area.
  3. In the contents area, select a Virtual I/O Server logical partition and select Configuration > Manage Profiles.
  4. Select the partition profile of your choice and select Actions > Edit.
  5. Click the Settings tab
  6. Select Enable for Time reference and click OK.
  7. Repeat steps 3 through 6 for the destination server and the destination Virtual I/O Server.
