3.6.1 Understanding the Relationship Between the XSCF and Physical Partition Times


3.6.1 Understanding the Relationship Between the XSCF and Physical Partition Times
The XSCF maintains the time difference between the XSCF and physical partition. This prevents the time difference between the logical domains and XSCF from changing, even when the physical partition is reset. Even if the time of the XSCF is changed by executing the setdate command on the XSCF firmware, the time difference between the physical partition and XSCF is maintained.
The XSCF time and physical partition time are managed in the following manner.
  1. When the power of the physical partition is on, the information on the time difference between the XSCF and physical partition is added to the XSCF time, and this value is set as the physical partition hardware time (TOD).
  2. At Oracle Solaris boot, the logical domain time is set based on the physical partition hardware time (TOD).

Note - Do not use the resetdateoffset command, except at the initial configuration of a physical partition, because it affects the time control mentioned above. The resetdateoffset command is used at the initial configuration of the physical partition only.
For the usage of the resetdateoffset command at the initial configuration of a physical partition, see the Installation Guide for your server.
