Even if the IO is startup some processes like CDJ, BVI cannot been startup
OS: Linux
OS Version: Red Hat Enterprise Linux Server release 5.8 (Tikanga) but can be applied to another OS

Root Cause: During the upgrade procedure Dollar Universe v 5.x has not been stopped correctly.
Check that the duas 5.6 processes belong to the correct user (ex: univa). To do so, you can use the command ps -efHwl | grep ux
If your process belongs to a user which is not the administrator, you will need to execute the ux_dus_rights command:

-Log in as root
-Shutdown Dollar Universe
-Execute the following: univa universe LOW
- connect you with univa
- uxstartup

Then proceed with the upgrade using an Administrator or Root account.

Fix Status: No Fix
