Hakoni,   The issue is likely due to it losing rights to the functions needed when it reverted to Express. So what I would suggest is that you try loading the trial version of the iDrac 7 license, then after you do that then Import your license via the vflash.   You can find the trial version here.     Let me know if this helps, or if you have any other questions.    
Hi, We have two old PowerEdge R620 servers  where the support has expired, both have Enterprise license idrac 7, but on one of them, the license suddenly disappeared after a power recycle, and is now of type "Express". Unfortunately I don't have any information in my digital locker for these servers, so I'm unable to recover the license from there. I have setup a recurring backup of the server profile to vflash on both. But on the host that has lost the license, it is not possible to select vflash to import back the profile, because the license probably doesn't anymore include the vflash operations..? Is the license actually backed up to vflash, and is it possible to recover the license from it somehow? Kind regards, Håkon    
Recover idrac 7 license from vflash?
