vSphere Compatibility Predictor – fling test

VMware has just released a new fling called vSphere Compatibility Predictoricon-icoIt is basically an upgrade checking tool. Validates if your currently running vSphere 5.5 / 6.0 infrastructure components will work with 6.5 or not.

This Fling scans all PSCs connected to a single
PSC. It will detect the versions of all the vCenter Servers connected to PSCs and all the Solutions connected to vCenter Servers. It will then depict the connectivity in pictorial form.

When you choose the Upgrade View in the Fling, it will show which Solutions are compatible with vCenter Server 6.5. This can help the administrator plan the upgrade in advance.


After accepting the Technical Preview License, the .zip can be downloaded. It contains the VMware-vSphere-Compatibility-Predictor-Setup-1.0.0-20170127.exe, install it on a Windows 2008R2/2012/8.1.



I have tested it with both existing vCenter versions: 5.5 and 6.0. Use the PSC/SSO credentials. (vsphere.local\Administrator). With the default settings you can login into a vCenter 6.0 only – that is using the LDAP port 636. So based on the versions you need the following LDAP ports:

  • vSphere 5.5 SSO: use the port 11712
  • vSphere 6.0 PSC: use the port 636

Otherwise you will get the following error:

Could not able to make the connection to PSC/SSO Ldap Server…


However the same will be displayed, even with wrong user/password, port, IP as well.


After a successful login Accept the thumbprint, then select the site (vCenters and PSCs will be displayed) and press Upgrade View. In our 5.5 example a couple of extensions are compatible with 6.5:

  • vCenter Intelligent Power Plug-in (EATON)
  • vShield Manager
  • VR Management
  • VDP 6.1

Do not forget to check the fling site!

DELL iDRAC Quick Sync NFC with PowerEdge R730

Recently we have received a couple of DELL PowerEdge R730 rack servers. Of course, each has already vSphere installed with the new HTML5 vSphere Web Client Appliance.


In our lab till now there were mainly IBM /Lenovo and Fujitsu servers, so the R730 was also new for me.


The 13th Gen server (of course it is great and fast) has a very special functionality, called iDRAC Quick Sync. This solution allows you to manage some of the 13th Gen Dell rack servers by touching your phone to the front bezel using the NFC technology. Sounds amazing, right?


The iDRAC Quick Sync is visible at back side of the front bezel

How to setup

  1. Power On the NFC capable 13th Gen Dell server
  2. Install the DELL OpenManage Mobile to your iOS /Android phone
  3. Enable the NFC on your phone
  4. Press the iDRAC Quick Sync button on the front bezel
  5. In the OpenManage app select the iDRAC Quick Sync Read option and touch the front bezel with your phone (can be password protected)
  6. After 1-2 sec a new iDRAC item will be listed in the app.

What is possible?

With this convenient mobile solution lots of information about the server can be polled.

  • Basic data, server components list
  • Server event logs
  • Firmware details (from all of the components, even from the PCIe cards)
  • Network (iDRAC) details: IPv4/6 and MAC addresses
  • Health (storage, battery, FAN, Power, Temp, Voltage..) status
  • Warranty info – based on the Service Tag the start/end date, order and customer numbers are displayed
  • Link to the components list.

This list can be refreshed whenever you want. The another great function is that e.g. the iDRAC network settings can be modified and applied on the server.

So if you have such DELL Rx30 server and NFC capable phone, it definitely worth a try!

vSphere (HTML5 Web) Client 6.6 – Fling Dashboard

Almost every week a new beta version of the vSphere HTML5 Web Client is released. As you already know the community loves this product: the site has more than 1400 comments, 63 bugs and a huge changelog with lot of improvements and bug fixes. The huge enthusiasm is understandable, because the HTML5 based client provides a modern, flat based much cleaner interface. Of course the most important advantage is the rocket speed response time.h5-icon

This year in March I also tested the first version. (For Hungarian readers: Zoli has also posts here and here) Since then, VMware has released the vSphere 6.5 VCSA including a “supported version” of the vSphere H5 Client. (bulid 4598948)


Unfortunately upgrading of this vSphere Client inside the VCSA is not possible currently. The only way to have the latest Fling (which is 2.19 – Build 4810256) is using the vSphere Web Client Appliance. The installation method is pretty much the same, as with the Bulid 3680819, but since the 1.17 – Build 4202128 a new way is available through the Fling Appliance Management Interface (FAMI). This web interface eliminates most of the CLI part – theoretically:)  Let’s check it.


  • Download the OVA, deploy it and boot it. You will get the following on the console:


  • On the VCSA6.5 the default shell must be changed to bash, this can be done via SSH.


  • Now we can use the Fling Appliance Management Interface (FAMI), which is available at https://H5_Appliance_IP_Address:5490 (On the port 5480 we can modify the IP, GW, DNS, hostname of the appliance). With the FAMI the VCSA registration can be done.
  • Looks great! Now we have two H5 Clients: the integrated one inside the VCSA and the latest one as an OVA appliance. Let’s check the latest H5 Client with opening the https://H5_Appliance_IP_Address/ui Unfortunately there is no UI, but an error message was waiting for me

A server error occurred.

[400] An error occured while sending an authentication request to the vCenter Single Sign-On server – An error occured when processing the metadate during vCenter Single Sign-On setup – null.

Check the vSphere Client server logs for details


Oookay. Look into the logs

root@vcsa65 [ ~ ]# /etc/init.d/vsphere-client show_log

At the end:

Recover Orphaned Virtual Machines

After several host network issues some of the VMs in the inventory were displayed as orphaned. No worries, this is an easy one 🙂


However in this state the VMs are not usable, but a few options are still available. To recover them there are the following possibilities:

  • simply migrate (cold vMotion) the orphaned VMs to another ESXi host. After the re-registration they will be active again.
  • remove (unregister) the VMs from the inventory, open the Datastore and add (register) the .vmx file to the vCenter server.

Usable KBs in this topic:

  1. Virtual machines appear as invalid or orphaned in vCenter Server (1003742)
  2. vSphere Docu Center

vSphere 6.5 is almost here – VMworld?

Everybody knows, that the vSphere 6.5 is in the tube and almost here. The public beta is running, we have seen a few breadcrumbs about the 6.5 (from vladan.fr, on reddit, etc.) The vSphere HTML5 Web Client fling is an awesome technical preview, I have also tried it. It can be the one of the biggest feature of the vSphere 6.5 from management point of view.
