Weathervane, a benchmarking tool for…

Weathervane is a performance benchmarking tool developed at VMware. It lets you assess the performance of your virtualized or cloud environment by driving a load against a realistic application and capturing relevant performance metrics. You might use it to compare the performance characteristics of two different environments, or to understand the performance impact of some change in an existing environment.

ECC Errors On Nutanix

When logging into a Nutanix cluster I see that I have 2 critical alerts.

1

With a quick search I found KB KB 3357 I SSH into one of the CVM’s running on my cluster, and ran the following command as one line.

ncc health_checks hardware_checks ipmi_checks ipmi_sel_correctable_ecc_errors_check

Looking over the output I quickly found this line.

I forwared all the information to support, and will replace the faulty memory module when it arrives.  Luckly so far I have not seen and issues from this memory issue, and I really liked how quick and easy it was to resolve this issue using Nutanix.

vCenter Fails after Time Zone Change

We recently changed our NTP server, and I needed to update all or hosts and vCenters.  I have a handy powershell script to update the ESXi hosts, but that script does not work on the vCenter servers.  I log into the server using port 5480 to gain access to the vCenter Management. I login as root and notice that the time zone is UTC.  I am in the Central time zone so I wanted to change it from UTC.  Turns out if you do that it break everything.  I had to learn this the hard way, and once I changed the time zone I was not able to log into vCenter.  I had to then go back and change the time zone back to UTC to regain access. Capture.

After SQL Installation Drives Inaccessible

Recently I setup a VM using standard best practices.  Such as using PVSCSI for the Database drives, and formatting them GPT.  Everything checked out so I passed it on to the DBA to finish up with the SQL installation.  Soon later I received an email from him saying the drives were inaccessible.  I had no idea why because I had setup a lot of VM’s the same way without any issues.  I did a quick Google search for “drive inaccessible after SQL installation”.  It turns out a lot of people have the same issue as me.  It is the result of Microsoft locking down the security for the data on the drives.  They set it up so only SQL could have access to the files to prevent certain security issues.  You can read more about it here.

Nutanix .NEXT

I was honored this year to be chosen to be a part of the Nutanix Technology Champions.  I have only recently started using Nutanix, but I could clearly see what made it different.  In an age with the Public Clould all the rage.  I could see something like Nutanix really keeping the private data center alive.  The Public Cloud is so popular because it is such an easy way to consume resources as you need them.  I see what Nutanix is doing how it is really converging everything.  Not only are storage and compute converged, but so are the underlying software.  One software package to rule them all instead of a seperate piece of software for every feature you need.

That is why I am so excited about being a part of the NTC, and the free pass I received to go to the Nutanix .NEXT conference.  Conferences can be really expensive, and I would like to thank Nutanix for investing in its community and showing its appreciation.  I know at it I will meet a lot of new people and learn a lot of new things.  Conferences are really about networking with your peers, and sharing knowledge.  For that reason I see them as valuable as any training.  Hopefully I will meet everyone who reads this post, and if you have not registered yet you can at .NEXT

Updating Prism Central to 5.0

Nutanix recently released the 5.0 code, and it has a lot of new really nice features.  In a future post I plan on going over some of the features, and detail why they are so important.

Before you start upgrading all of your Nutanix host you should first upgrade Prism Central to 5.0  This server gives you an overview of all your Nutanix clusters and some management capabilities.  I am still fairly new to Nutanix so I was not sure how to upgrade Prism Central.  Usually you can upgrade from within the Nutanix console, but with this being a brand new release you had to download it directly from the website.  Sometime soon in the future it will be a part of the automatic upgrade within the Console.

At first I was a little confused about how to upgrade.  You would think there would be a separate upgrade for Prism Central since it was originally a  separate install.  Instead the update is included in the AOS 5 download.  Download the complete AOS 5.0 and also download the Upgrade Metadate File.
2017-01-17-08_43_02-nutanix-portalOnce you have that downloaded everything login to Prism Central. Next click the gear icon and then click upload the Prism Central Binary.  Now point  it to the AOS 5.0 download and the metadate file.  Click upgrade and soon you will be running Prism Central 5.0.  2017-01-17-08_46_42-nutanix-web-console
