If you already have a case open with the Response Center, there is not much I can add to that, but, here are some observations
ON the Cell Manager (unspecified OS-type) run
omnisv status
and see if the service "hpdp-idb" is running. If it is not, this is probably the cause for this problem.
This was a known issue when upgrading a Windows cell manager
Problem:
During the update to DP 8.1, the hpdp-idb service does not start.
As a consequence, the import of the IDB (core update) does not work and needs to be repeated
The DP 7.0 installation has been done in a way that binaries and data files are located in C:\Program Files\OmniBack.
The same applies for D:\Program Files\OmniBack (or other volumes).
The update to DP 8.1 creates a file "C:\Program" and does not clean it up after the installation
Solution:
The solution consists of the sequence of the following steps (assuming that common path C:\Program Files\OmniBack has been used).
1) Delete the file "C:\Program". (May not be on C:, but the filename is always 'Program'
2) Do "omnisv stop" and "omnisv start".
3) Use "omnisv status" to check that all services have been started.
4) Check the location where the IDB has been exported to (default is C:\Program Files\OmniBack\tmp\export):
You should see a mmdb and a cdb folder there.
5) Open power shell and go to C:\Program Files\OmniBack\bin
6) Run the import manually:
PS C:\Program Files\OmniBack\bin> perl omnimigrate.pl -import -shared_dir "C:\Program Files\OmniBack\tmp\export" -force
