Migrating from Previous Releases
Migrating your Configuration to Host-Based Management
Appendix B

Assumptions and Limitations
The New Host-based Management functionality provides a process to migrate a major
portion of the configuration on the OpenView DTC Manager PC to the HP e3000 host. In
order for the migration to work in the most consistent manner possible, the defined
process makes the following assumptions and compromises.
The Migration process consists of four major steps. These steps are described in more
detail later in this document. The four major steps are:
1. Run the PC Migration tool on the OpenView DTC Manager PC to create a file that
contains all the NMMGR Maintenance Mode commands needed to create an
equivalent configuration on the HP e3000 host.
2. .On the HP e3000 host, remove any DTC configurations from the PC-Based tree in
the NMCONFIG file that aren’t in use or should not be included in the migration
process. Change the configuration to Host-based.
3. .Use the file created on the PC and transferred to the HP e3000 host as the input file
to NMMGR to create the equivalent DTC configurations in the NMCONFIG file.
4. Run the Host Migration tool integrated into NMMGRVER that will merge the PC-Based
DTCs configured in the PC tree into the Host-based tree.
Assumptions
The migration process is designed with the following assumptions.
1. The PC Migration tool will use the DTC Label assigned to the DTC on the PC as the
DTC name when the DTC is added to the NMCONFIG file. If a DTC with that name is
present in the host-based tree of the NMCONFIG file the NMMGR commands created by
the PC migration tool will overwrite the DTC configuration.
2. The Host Migration tool is designed to merge the DTCs configured in the PC-based
tree into the Host-based tree. The tool will try to merge all of the ldevs from the
PC-based DTC into the corresponding Host-based DTC. The DTCs in the Host based
tree are matched to the DTCs in the PC-based tree by finding the matching DTC
Node Name. The DTC name in the Host-based tree is maintained.
3. All Serial ports on the DTCs will be assigned a default profile. This is necessary
because with OpenView DTC Manager, each port on the DTC can to be assigned
unique characteristics. This can easily cause the number of unique ports on the host
to exceed the number of available profiles. It is also very difficult for an automated
tool to merge the port configurations from the PC and the profiles from the PC-based
tree into the Host-based tree.
4. All PAD devices will be assigned a default profile. This assignment will eliminate
any non-default PAD device profile number. This case has the same difficulties as
was found for TIO serial devices.
5. .The default profiles will be created if they don’t already exist in the Host-Based tree
in the NMCONFIG file. You can modify these profiles to apply any desired
customizations to the ports to which these were assigned. The default profile
assigned for each port type are:
Terminal TR10AUTO
printer PR18AUTO
host HOSTAUTO
