Will this fix the Ghost vulnerability?

ndyer39

Hi Chuck,

That's correct - 2.2.5.0 includes fixes for Ghost (glibc). There will be similar fix releases for 1.4 and 2.1 coming down the line.

When would CS220 be available for update?

jrhall

Thanks for fixing the false positive hardware failures!! So far so good.

ndyer39

Should be available soon. You can check if your array is whitelisted or blacklisted in the Infosight->Assets tab, click your firmware on the array to load the Software Upgrade popup screen. In this instance, the firmware running is lower than 2.0.8.0, so needs to upgrade to 2.1.8.0 before getting to 2.2.5.0

thanks ....so if i was "blacklisted" it would show up here?

Capture1.JPG

even when i go to the downloads.. nothing to download https://infosight.nimblestorage.com/infosight/download to manually download to workstation then upload to nimble.

ndyer39

Whilst we're in the process of running a whitelist/blacklist process for firmware releases we don't allow customers to manually download the firmware as it invalidates the whole process we're trying to mitigate against - which is updating firmware which could cause a problem.

Click on your firmware where it says "2.1.5.0-122684-opt". You'll get a pop-up, what do you see? It'll tell you if you're blacklisted or not.

aaron_cirilo

ahh.. ok yea it's blacklisted... is there a reason usually for this? we have Premium support thru 2016

Time to give support a call - it's most likely picked something up from the autosupports which means an upgrade of some sort may run into a known issue.

Got to love data analytics for this sort of pro-activeness in fault finding!

There was a blog post written up on the weekend about a customer who upgraded their system to 2.2.5 and noticed a huge improvement in cache hits thanks to the new algorithms. We'll publish a blog or two on the new algorithms and the real-world measured benefits via Infosight in the future...

Hey Nick - Can I confirm we don't need any PSP/SRA updates for this ?

ndyer39

Hey James,

There is a 2.2.x VMware MPIO PSP & Site Recovery Manager SRA. If you're upgrading from 2.2.3 to 2.2.5 there is no action to take. If you're going from 2.0.x or 2.1.x then the SRA should be updated first. The MPIO PSP can be done at a later time - it's not mandatory to keep it lock-step. This also goes for the Windows Toolkit, too.

james_faulkner

Thanks Nick

We are going 2.2.3 – 2.2.5 and have VMWare MPIO PSP 2.1.0 installed, SRA 2.1.0 and Win Toolkit 2.1.4 so should be good to rock.

Do we need to upgrade the Toolkit on the servers for the snapshot to work? If so I still have to schedule to do it after hour as those servers will need to be restarted after update. We currently have toolkit 2.1.3.

ron_fisher

Still new to Nimble land. Do we typically need to upgrade our ESXi connection manager software with every release?

rugby0134

Not required unless it's noted in the release notes.  The 2.2.1 code release is have a couple feature, but 2.2 code will still wirk with the 2.1 interface.

ndyer39

Hi Jason,

There's no need to stay 100% lock-step with updating the host side Connection Manager software for Windows or VMware - it's only if you wish to take advantage of any new features that the software provides; otherwise the snapshot functionality (for example) functions the same.

I'm told from support that we QA and test the host side software to be 3 iterations out from the array firmware; if you're on 2.1.3 today then you are supported to go all the way up to 2.4. This can change at any moment so always check the release notes!

jliu79

Thanks Nick, that's good to know.
