Leela, Would you private message me the svc tag for the server? Also, would you verify if the firmware inventory exists in the device pane, if not then you may need to delete and reinventory.  After that if the issue reoccurs then you may want to run a TSR and upload it to upload. dell. com Let me know what you see.
We are not able to update firmware from Dell OME on this server, where as other Dell servers are able to update with out any issues, please assist
The device Service Tag could not be verified in Dell OME
