OpenManage Enterprise extension not picking up all devices

Hi,

We've just put in a new installation of OME 3.3 and SupportAssist Enterprise 4 and purchased 12 new pieces of Dell equipment. OME has 12 devices, 10 servers and 2 switches and are green with no errors. SAE has the extension installed, the credential profiles and account credentials are setup correctly. When the extension runs it picks up 8 of the devices (4 servers and 2 switches) and are imported, but 4 servers aren't being imported through the connector.

I've tried: -

Removing the extension and re-adding it

Rebooting OME, SAE and the servers

Reviewing any differences on the iDRACs between the servers that are and aren't working

Adding the servers into SAE manually - this works successfully

 

Anybody have any ideas or logs that can be reviewed to determine where the fault exists?

 

Thanks in advance!
