Update Dell 740XD FW for SAS,iDRAC, network, etc in vCenter cluster
Hello Everyone. We currently have 10 Dell 740XD servers in a vCenter cluster. 3 of those servers were just added a week ago and have all firmware, bios, SAS, network, iDRAC, etc all updated. The other 7 have been in production for a few years and the only updates we have done recently is the iDRAC (although it is now behind as well).
I am always very cautious when doing these firmware updates just in case the ESXi host/vCenter has issues with it. Since the 3 new servers are working I would suspect it should be fine, however I wanted to double check to see if there is anything i should be aware of. The three new servers, while part of the vSAN, do not have their disks claimed yet. Not sure if that makes a difference.
I was going to update one of the older servers over the weekend, let it sit for a day or two to make sure the updates were fine. Hoping that even if it is fine, its not causing some issue in the background that we dont see for a while.
Thank you.

My plan was to do like Andrew suggested, do one a week (as long as the servers being on different firmware versions is ok). If I did two servers over a week or two with no issues, then I would feel pretty confident that I could take a weekend and do the rest.

and are these vSAN Ready Nodes, or just Dell R740XD because the two are different.

These three new servers should have been firmware updated before installation, but as they are not running vSAN at present pose little risk, but do check firmware's against vSAN HCL.
If you update a ESXi host, the vSAN Health check does verify hardware against the online HCL.

I wasn't sure if that would pose an issue with the 7 servers so I was thinking I should probably update them as soon as I can.

Which is why we do ESXi build updates and firmware updates at the same time.
