i want to upgrade the UCS from 2.1 relase os to latest version, is there any harm to doing this ? will the upgrade needs some path prequsist(2.1 to 2.2 and then ..... to 3.x).
can i have any reference document for doing this.
Unless there is something in the release notes that will benefit you, stick with 2.1.
I agree in not upgrading unless you need to, but if you decide too, each release has a document going over what is updated, and one that includes the required upgrade path.
My chassis are all running 2.2 right now. As far as I know, 3.0 is only for UCS Mini at this point.
I can confirm 3.0 is for UCS Mini. I whent on the rather excellent UCS mini training day at Cisco in Feltham UK. If you look at the current Blueprint for the CCIE DC, its says UCS 2.x.
