Enigma Protector

Hello,
What exactly means the following comment from Enigma Protector Help:
"(*6) Hard Disk Serial hardware lock failed to get the serial number if the operation system is installed on a RAID hard disk drive "?

1) Does 'failed' means, that the corresponding hash value of this serial will be always constant 'zero' value ?
2) Or this hash will change unpredictably and , as result, will invalidate registration key with no matter how much changes is allowed for this lock?

The first is not so bad, we just loose one lock, but the second is really bad!

Thanks!

OK,
I've got clarification by email from Enigma team.
If nobody is interesting in this issue, the post may be closed.
Thank you, Enigma
