Unable To Connect To The MKS: The Operation Is Not Allowed In The Current State July 1, 2014

Today we are running a VMware Troubleshooting workshop and one of the delegates came across the following error when trying to open a VM console through the vSphere Client and also the Web Client. This was the case with all VMs.

UNABLE TO CONNECT TO THE MKS: THE OPERATION IS NOT ALLOWED IN THE CURRENT STATE

Here are our solutions to the issue

  1. We noted down the Datastore for the VM and then removed the VM from the Inventory in the vSphere Client. We then browsed to the datastore and added the VM back to the inventory by Right-Clicking on the .VMX file. However with quite a few VMs, this may take a while.
  2. We rebooted the ESXi host, all VMs then came back working (yes a bit extreme, but it did the job, thank you vMotion, if live environment possibly done with no downtime).

VMware web Client reports Empty Inventory May 6, 2014

Today I’ve been playing with a course build for the VMware Troubleshooting 5.5 workshop

I got to the 3rd lab, this lab involves me using the Web Client to connect to my vCenter and then make some changes to my environment and then use the log files to verify the changes.

The client reported Empty Inventory

Then I checked the services and found that the VMware vCenter Inventory Service was started, so I gave the VMware vCenter Inventory Service a restart and all was good with the world.

It’d be boring if everything worked first time.

Upgrading VM to hardare version 10 with vSphere webclient March 10, 2014

Today we’ve been looking at the web client in VMware vSphere 5.5.

One of the labs today was creating a VM in the traditional VMware vSphere client, the issue with this way of creating a VM, is that the vSphere client will only allow us to create the VM up to hardware version 8, but vSphere 5.5 supports up to Hardware version 10.

We now have a VM that is hardware version 8, in order to upgrade to hardware version 10, we use the vSphere 5.5 web client.

The process is as follows.

  1. Power down the VM to be upgraded.
  2. Right click the VM and click Edit Settings
  3. Click the arrow next to Upgrade to expand the upgrade properties.
  4. Select Schedule VM Compatibility Upgrade
  5. Ensure that compatible reads ESXi 5.5 and later
  6. Click OK
  7. Power on VM.

Also note that the above can be scheduled to upgrade during VM Power cycle if you don’t want to power down the VM at this point.

I’ve also produced a little demo video on my Youtube channel

Setting DNS and Routing IP settings in the vSphere 5.5 webclient March 9, 2014

I’ve just connected my two ESXi hosts to my VMware vCenter Server, I then accessed the webclient and setup my DNS and Routing settings.

I expected the setting to be accessed as follows.

Hosts and Clusters > Highlight Host > select Settings

This however is not the case.

Instead

Hosts and Clusters > Highlight Host > Select Networking > Highlight TCP/IP Configuration > Edit

I suppose ‘yes’ that’s where it should be.

vCenter Server Appliance 5.5 root account locked out after password expiration March 9, 2014

I’m teaching a vSphere 5.5 Install, Configure and Manage course next week and as part of my prep I just like to make sure that all is ready to go for Monday morning.

One of the snags I came up against was the inability to login to the vCenter appliance, I checked my passwords, but still no successful login.

‘Hang on.’ I thought. ‘SSO has a 90 limit for passwords.’ That was indeed the case.

I found this really handy KB document and following the steps have fixed the issue.

On the VMware 5.5 courses we talk about the new VMware Virtual SAN technology, generally this topic proves to be quite popular and I get asked where delegates can get more information.

A really good resource is VMware’s Hands on Labs site. This site allows you to play with VMware technologies via some pretty decent Labs.

http://labs.hol.vmware.com and select the vSAN lab.

Also check out VMware’s Storage Blog.

http://blogs.vmware.com/vsphere/storage

Finally and most relevant to me as a VMware Certified Instructor, VMware have released a 2 day VMware Virtual SAN: Deploy and Manage course.

The course covers the following.

Course Objectives

 

By the end of the course, you should be able to meet the following objectives:

Define the key components of a software-defined data center

 

  • Identify benefits of software-defined storage solutions
  • Compare and contrast disk types and storage technologies
  • Explain file, block, and object-oriented storage
  • Identify Virtual SAN requirements, use cases, and architecture components
  • Plan and design a Virtual SAN deployment
  • Configure Virtual SAN clusters
  • Identify benefits of storage policy-based management
  • Scale a Virtual SAN deployment based on storage needs
  • Monitor Virtual SAN
  • Troubleshoot Virtual SAN
  • Identify the integration of Virtual SAN with the VMware product portfolio
