Migrating your Configuration to Host-Based Management

4. If the card type configured in the Host-Based DTC does not match the card type in
the PC-Based DTC then the card is not merged into the Host-based tree and the
Host-based DTC will have the same configuration discrepancies as described in
paragraph 1 and 2.
5. If the port type of TIO or PAD devices in the Host-based tree does not match the port
type of the port in the PC based tree, then the PC-Based port configuration is not
merged with Host-based configuration. The port will have the same configuration
discrepancies as described in paragraph 1 and 2.
6. If the profile name copied from the PC-based DTC port DOES NOT exist in the
Host-based DTC configuration, then the configuration is incomplete and will be
detected by Validation. You must manually create the profile.
7. If the profile name copied from the PC-based DTC port DOES exist in the Host-based
DTC configuration, then the parameters may not be the same as those in the
PC-Based Profile. You must manually verify that the parameters in the profile are
correct.
8. If a PAD device name is defined in the PC-Based DTC that is not defined in the
Host-Based DTC, the device will have no X.25 address assigned. This is an invalid
PAD device configuration and will be detected by Validation. You must manually
correct the configuration.
9. If a DTC exists in the PC based tree that was not created in the Host-based tree (a
DTC with a matching DTC Node Name was not found), then the DTC will be copied
to the Host-Based tree as a non-managed DTC. (LAN Address = 00-00-00-00-00-00).
All ports with an ldev number assigned in the DTC will be assigned the default
profiles.
10. If you want to define unique parameters for ports, i.e., port name, you will be limited
to the 1024 unique profiles available for the DTS subsystem.
Configuration Issues to Consider before Migrating
This section describes different configuration situations that you may have on your
OpenView DTC Manager PC and Host systems and what you can do to reconfigure some
items to make the migration go as smoothly as possible. This section also describes what
configuration changes you may need to make after performing the migration process. In
all situations these configuration considerations only need to be applied to the system
that will become the host system that will manage DTCs. If you want, you can elect to
distribute the DTC to more than one host.
