Migrating your Configuration to Host-Based Management
Appendix A

2. .On the HP e3000 host, remove any DTC configurations from the PC-Based
configuration in the NMCONFIG file that aren’t in use or should not be included in the
migration process. Change the configuration to Host-based Management and remove
all DTCs that may still exist in the Host-Based configuration.
3. .Transfer the file created on the PC to the HP e3000 host and enter the following
commands to use the file as input commands to NMMGR to create the configuration in
the NMCONFIG file.
:file :file nmmgrcmd=<filename>
:nmmgr
where <filename> is the name of the file transferred from the PC.
4. Run the Host Migration tool integrated into NMMGRVER and merge the PC-Based
DTCs configured in the PC-based configuration into the Host-based configuration.
5. Create or modify any profiles that have been assigned to DTC devices if you want to
apply customization to the DTC devices. The profile names assigned by the
migration process will either be a default name assigned by the PC Migration tool or
the profile name that was assigned to the port in the PC-Based Configuration.
6. Validate the NMCONFIG file and perform any changes needed to resolve any
configuration discrepancies that are found. Perform a DTC Shutdown and Restart
using DTCCNTRL.
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. The PC Migration tool will assign a default profile to all Serial ports on the DTCs.
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. The PC Migration tool will assign a default profile to all PAD devices on the
DTCs.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
