When you modify DTCs
Each time you modify the configuration of a DTC you must:
1 Create a new export file on the original host using the dtcexport command.
2 Copy the file to each potential adoptive host.
3 Import the file to each adoptive host using the dtcimport command.
When you add new DTCs
Each time you add a DTC to your configuration you must:
1 Create a new export file on the original host using the dtcexport command.
2 Copy the file to each potential adoptive host.
3 Import the file to each adoptive host using the dtcimport command.
Note To be sure that the adoptive host can manage the DTC(s), you should verify that it
can receive boot requests from the DTCs that it will manage (own) in the event of
original host failure.
