UCS firmware version question

Hello guys!

 

I've seen from Cisco download for UCS B series firmware versions, there are 2 latest versions which 2.2.(1d) and 2.1.(3c), what are the different between these 2 versions? My current firmware is 2.1.(1b), should I update to 2.1(3c) or 2.2.(1d)? Thanks.

Hello,The difference is that

Hello,

The difference is that they belong to different chains (one is 2.1 and the other 2.2) where we made some improvements in the firmware.  UCS, unlike other Cisco devices, do not follow an specific order in the firmware versions released; so you may see, at anytime, how a 2.1x version may be newer than a 2.2x version; precisely cause that 2.1x will be the newest one for the 2.1 chain while the 2.2x will be the newest one for the 2.2 chain but release on a different day.

The other difference is the bugs we fixed on each release, which might not be included in the other one.

The UCS behavior can also change from version to version, and here is an example:          https://supportforums.cisco.com/discussion/11673921/default-zoning-users-heads-ucsm-21

If you want to see how one version differs from the other, what you can do is to check the release notes for each one:

I would migrate your

I would migrate your infrastructure (=UCS Manager, Fabric Interconnect and IOM) to the latest 2.2.1 release; you could keep your server

1) at the current 2.1.1b

2) the newest 2.1.1 release

3) upgrade to 2.2.1

See the attachment (from the 2.2.1 release notes) which shows that a Infrastructure release of 2.2.1 will interoperate with server at 2.1.X.

Hi Kenny,

If I were you, I would read the release notes to see how it helps/hurts my environment before making any decision, however 2.2 adds some new cool features.

Sorry for the late reply. I was out of town of last few weeks. Finally got back and read the documents and decided which version to go with. 

 

Have you guys done with 'Auto Install' feature on UCS manager to upgrade for the UCS? if you have, after the upgrade, can you still roll back/downgrade to the previous version? Thanks.

There is no limitation in

There is no limitation in regards to downgrading the firmware no matter the method you use to upgrade.
