vRealize Orchestrator : Add new port group to standard virtual switch to all hosts of ESX cluster

There are situations when one need to add a new port group to the existing standard vSwitch in vCenter. This is easily configurable in the vCenter in the host configuration. This can be done manually on the small number of hosts, however on bigger number it can be really annoying. What offers vRO as basis. In the built in workflow list under the “Library->vCenter->Networking->Standard Virtual Switch“, one can find a workflow “Add port group in the standard virtual switch“. It’s good for the start, so let’s see what it needs Continue reading

Powershell : A simple use of DSC

I’m a great PowerShell fan, I think it’s the second best (or maybe first one) thing Microsoft bring to IT world – for me still the one and best is MS Exchange.
Some time ago MS introduced a thing called Desired State Configuration, as I’m correct it was with PS 3.0, for sure with PS 4.0.
You can read a lot of DSC just to google it or go to MS site. I won’t explain how DSC works and what is the pull server, how to enforce configuration compliance, etc …

For my compliance I’m using SCCM, however I found Powershell DSC really useful for my initial server configuration, so I’d like to share how easy and handy is to build some initial server configurations – “Make it smart, make it simpe” – from this starting point one can go wherever … sky is the limit ๐Ÿ™‚ Continue reading

vRealize Orchestrator : Find network card by MAC

In this post I’ll focus mostly on code for creating simple vRO action to find a virtual machine network card by its MAC address. A use case for me was to set and IP address on VM with multiple network cards or delete a network card with specific MAC address. So instead of creating a new workflow I decided to create an action.

vRealize Orchestrator โ€“ Workflow to change DRS setting to default on single VM

In the post vRealize Orchestrator โ€“ Workflow to change DRS setting to default on single VM I presented the workflow to change DRS to manual on single VM. Now it’s the time to change this setting back to the default one, as it was. So to do this it’s quite easy to make a copy of previously create workflow.

And just edit the code of “Scriptable task”, because input parameter and attributes remain the same as in workflow described in previous post. Continue reading

vRealize Orchestrator – Workflow to change DRS setting to manual on single VM

Multiple times in multiple workflows, Iย needed to have VM not being migrated during the workflow run. Easiest way is to disable DRS on the VM. Well, it seems that DRS setting does not belong to VirtualMachine object, DRS settings is part of the ESX Cluster object. We’re still able to to set setting individually per VM, however it has to be set on ESX Cluster level not on the VM itself. I was pretty sure, that there built-in vRO workflows for such simple setting … However, it’s not. That’s what VMWare offers by default

  • Add DRS virtual machine
  • Add virtual machines to DRS group
  • Create cluster
  • Delete cluster
  • Disable DRS on cluster
  • Disable HA on cluster
  • Enable DRS on cluster
  • Enable HA on cluster
  • Remove virtual machine DRS group from cluster
  • Remove virtual machines from DRS group
  • Rename cluster

If there is a need and there is no solution – it has to be created.

VMware vCO โ€“ cloning VM, using cluster name instead of host and getting less used datastore of chosen host. โ€“ Part 2.

In the Part1 I have created a vCO workflow to get an ESX host from provided ESX Cluster name to pass it to the cloneVM action in vCO.
So now is time to get less used datastore of this host as another parameter for the cloneVM action. My workflow looks like this
GetLessUsedDatastoreOfHost

Powershell, not only Microsoft …

PowerCLII reckon, that Powershell is one of the best Mictosoft products. It came alive when Vista/Windows Server 2008 (codename Longhorn – who remembers this ๐Ÿ™‚ ) were released. I’m great Powershell fan, it allows to manage many Microsoft products, but not only. Once, I had to change few options in VMWare environment: “Memory/CPU Hotplug” and “Check and upgrade Tools during power cycling” as on screen below

I could do that manually, but changing manually settings in over 5 virtual machines is simply waste of time.ย  Continue reading
