3.5.6. Frequently Asked Questions
Software License Management
Is the Manufacturing Control Number (MCN) unique to a system?
Yes, each hardware system is assigned a unique MCN when the system is built.
For Intel based Next Generation OS 2200 systems, such as the Dorado 400 or Dorado
4000, the 1 to 16 character MCN is derived from the manufacturing tag number or UUID.
These MCN values are unique for all systems.
Is the Software Control Number (SCN) unique to a specific MCN?
Yes, the SCN is the software profile that is entitled to a specific hardware system MCN.
A hardware system can have multiple SCNs, one for each workload. For example,
MCN 1 can have a general IOE (SCN 0000001) and an SDK IOE (SCN 0000002)
registered. These SCN profiles cannot be registered on another system, for example
MCN 2. MCN 2 has its own unique SCNs, for example general IOE (SCN 0000003) and a
Business Information Server (BIS) IOE (SCN 0000004).
What is the difference between a software upgrade order and a software
update order?
A software upgrade occurs when a hardware change is made that requires the software
to be relicensed. For example, if the performance level of a system is upgraded to a new
level, the software must also be licensed at the new performance level. This order
creates a new SCN.
A software update order is created when the latest available software release is
requested. This order does not create a new SCN.
Is a specific SCN locked to an MCN for the life of the MCN?
If a system is never upgraded, the original SCN will be the same for the life of the
system. If the system is upgraded, a new SCN is issued.
What happens if a ClearPath OS 2200 product key tape is accidentally
registered on the wrong system?
Find and register the software product key tape with the SCN on its label that matches
the SCN on the registered image enabler key. If that does not correct the problem,
contact the Unisys Support Center for assistance. Once the correct keys are registered,
you should use SOLAR to unregister the keys with the wrong SCN.
Can multiple software product key tapes be registered with multiple
SCNs on a ClearPath OS 2200 Release 10.0 and higher system?
Yes, each licensed software group has its own SCN and it is registered on a system.
There can be multiple SCNs registered on a single MCN, depending on how many
licensed software groups the system is authorized to run. Each licensed software group
has a unique SCN, and a unique Exec Image Enabler key.
