Live upgrade UCS 2.0(5a) to 2.1(3a)

[Fred Weers]

Hi Guy's

Previously I have updated my UCS live from 1.3 to 1.4 to 2.0

However now I've read in a article (that I can't find anymore) that there is a issue running 2.1 I/O Modules with 2.0 CIMC Controlles and server BIOS.

Any reassuring thoughts regarding this ?

Fred,

I personally have never read that caveat, what is recommended is to always run the same version on components that use the same firmware bundle, in other words....  For a B series upgrade, you need the Infraestruture bundle (include firmware for Fabric Interconnects, IOMs and UCSM) and also need the Server bundle (which includes the firmware for the CIMC, BIOS and Adapter).

Bottom line, the recommendation is to run exactly the same version for components that use firmware that come from the same bundle BUT,  UCSM 2.1 introduces an enhancement: "Mixed version support (for infra and server bundles firmware) "  wich allows the combination of SOME infraestructure bundles with some server bundles.

"Operational enhancements"

These are the posible configurations I am aware of:

2.1(1f) infrastructure and 2.0(5a)+ server firmware

2.1(2a) infrastructure and 2.1(1f)+ server firmware

I hope that helps.

Kenny,

Thanks for your reply...

So does this mean that the upgrade form 2.0 to 2.1 is mostly the same as 1.4 to 2.0

By looking at this document, I see that 2.1(3a) bundle software is comatible with 2.0(5a) server firmware.

Hope I get this correct.

Fred,

Nice to see that table (I had not seen it), I wil free up some memory

According to the table, 2.0(5) server bundle is compatible with 2.1(3) Infrastructure bundle, if you understood it that way, you are 100% correct.  <<< Thanks for sharing the link with ALL the compatible mix possibles.
