I have a few B2000M3 servers that have firmware 2.0 (3c). I would like to upgrade to 3.1 (1e). Can I jump from firmware 2.0 (3c) straight to 3.1 (1e)? Or do I have to go to 2.1, 2.2, 3.0, then 3.1? Please advise. Thank you.
If you reference the guide below specifically Table 7 it will show you the Minimum Software Versions for Blade Servers. For the B200 M3 Server you can see which firmware versions you need for the specific Fabric Interconnect you are running. Under the link I uploaded a snippet of the section.
If these answered helped you please mark this post as a solution so others can find this information readily.
I assume your UCS infrastructure is currently on 2.0/2.1?
Upgrade from 2.0.3 to 3.1.1 would need a two step upgrade from 2.0.3 -> 2.2 and 2.2 ->3.1.1e
So the steps are
1) Upgrade UCS infra to 2.2.x release
2) Upgrade blades to 2.2.x release
3) Upgrade UCS infra to 3.1.1e
4) Upgrade blades to 3.1.1e or a suitable release
As mentioned in the link
"Before upgrading to Cisco UCS Manager Release 3.1, ensure that the existing infrastructure and server bundles are on a Cisco UCS Manager 2.2(x) release, or later releases.
Upgrading from infrastructure bundles earlier than Cisco UCS Manager Release 2.2(1a) is not supported."
Hope that helps
