Enabling Nutanix “Stargate” I/O statistics page access with allssh command, AOS 5.5 edition

Finally got my hands on AOS 5.5 and upgraded our lab Nutanix cluster to this version.

In my earlier post I described how to manipulate “iptables” rules to allow access to “Stargate” or “port 2009” pages. Stargate page contains lots of detailed information of I/O operations, more info in my earlier post. It seems that “iptables” configuration has changed in this version.

In versions prior AOS 5.5 “iptables” chain used was called “WORLDLIST”. In AOS 5.5 the name of the chain has changed to “MGMT_OPENFROMALL”. This requires changes in “iptables” commands used.

Nutanix AHV: removing corrupted images from catalog

For some reason I managed to upload images into Nutanix AHV image catalog that were corrupted. This might be a browser related issue, I have to do some digging in order to find root cause for the problem.

One symptom of image corruption was that all the controls for the image were missing from the Prism GUI. The image was there, but no controls and there was no way to remove the corrupted image.

Solution:

  • Login into one of the CVMs as nutanix user
  • Launch acropolis CLI: acli
  • List images: image.list
  • Delete images: image.delete

Visio by DPTPB: Rack Stencil (V2)

April 24, 2017 Visio by DPTPB release update notes

Shape placement and spacing with the original V1 DPTPB rack shapes has been a manual process. Fairly easy to do, but still required some effort. I’ve addressed placement / spacing issues with new dynamic rack shapes with automatic placing for both front and rear view rack shapes.

Visio by DPTPB: V2 stencils, finally done :)

April 24, 2017 Visio by DPTPB release update notes

Finished with updating remaining DPTPB stencils to follow “V2” design, where all data associated with the shape is now within top-level shape and rear view shapes have connection points to match rear view rack shape. Like with previously updated DPTPB stencils, new “Rack”, “NetApp Controller” and “NetApp Disk Shelf” shapes look pretty much the same as the old ones, but under the covers new shapes are using completely new design.

Fun part of learning new stuff and building new shapes is over, now only the more tedious part of documenting the changes remains 🙂 In this post I will cover the changes on high level, more in-depth info in upcoming posts.

Nutanix AHV + Brocade using native VLAN per port

Got one of our Nutanix demo boxes back from the field a while ago and set it up again in our demo lab.

Our lab network is VLAN segmented and the last time I did similar exercise, I had to set Acropolis Hypervisor (AHV) to send tagged frames also for management (CVM/Hypevisor) traffic. Instructions for this can be found from Virtual LANs for your Acropolis Hypervisor Virtual Machines. This includes modifying bridge “br0” on all AHV hosts , one AHV host at time. And setting each Controller Virtual Machine (CVM) to use VLAN tagging.

However in the post above Nutanix recommends CVM and Hypervisor traffic to use “untagged” (or native VLAN).

I was wondering whether you could use native VLAN setting for management traffic by modifying switch configuration and skip making changes to AHV hosts and CVMs. It would be much easier especially if you have many AHV hosts. Just log in to your switch and make changes in one place rather than logging into each and every AHV host / CVM separately.

Visio by DPTPB: Nutanix stencils (V2)

March 15, 2017 update notes for Visio by DPTPB stencil collection

Executive Summary

  • Completely rebuilt/redesigned DPTPB Nutanix Visio stencil
  • Bye-bye for original Nutanix rear view shapes
    • I was never a fan of the original raster image based Nutanix shapes
    • So I made my own modular vector image based Nutanix rear view shapes
  • All rear view Nutanix DPTPB Visio shapes come now with connection points for easier shape placement
  • Separate NIC shapes
  • Data is now within top-level shapes
    • Like with all new style DPTPB shapes
    • Easier to access “Shape Data” window by clicking top-level shape
      • Not really a problem with Nutanix shapes, but was a major source of frustration with switch shapes
      • Now both Nutanix and Switch shapes behave similarly
    • Both front and rear view shapes
