VXRAIL node incompatible

So what you are encountering is a thing called KGS (Known Good State)
Basically its a mechanism added to prevent hardware to be added when it can cause a firmware mismatch in the cluster

I cant recall which way the message is but what I think its saying for example:
component bmc version 3.36.36.36 is incompatible with compatible version 3.34.34.34
The node has 3.36.36.36 as its idrac fw and your cluster is running an older version 3.34.34.34 (or it might be vice versa but I think I am right)

Basically if you node is at higher revision that the cluster supports then KGS will basically try and prevent a node add until you either upgrade the cluster to a supported level ( higher than the node is fine too) or there are other means around it (that would require a support engagement) if you do not wish to upgrade your cluster - but obviously considering all the security fixes etc gone into later code that would be the preferred option (all things being equal)

Thanks for reply

The firmware in old node is : 36.36.36.37 the new one is : 36.36.36.36.

Hmmm

Something isnt right there 

 component boss version 2.5.13.3022 is incompatible with compatible version 2.5.13.3020.

2.5.13.3022 shipped with 4.7.400+ 

2.5.13.3020 shipped with 4.7.30x 

But whats bugging me is I dont recall 3.36.36.36 shipping with VxRail

Have a look at https://dl.dell.com/content/docu97738_VxRail_4.7.x_Support_Matrix.pdf?language=en_US and compare the fw revisions and you will see what I mean

I would definitely recommend engaging support on this

I would definitely be engaging support to see whats going on

I will ask for Support

anyway I really appreciate your Help
