Downgrade HBA firmware

I have installed latest firmware bundle to my Dell Poweredge R740 server but the HBA firmware is not compatible with ESX 7.0U2. So I have to downgrade it to older version of firmware. 

Is it safe for me to just install the older firmware in iDRAC? Will there be any issue if my HBA firmware it not same as other firmware version?

Hello, you can use the iDRAC and LCC both to update and roll back the firmware. This can sometimes correct any issues encountered with firmware updates, but it isn't a 100% guaranteed fix. But as I saw in this article you might need to put your host in maintenance mode whilst doing the process. https://dell.to/3SWGoLV


Hope that helps!
