Automate vSphere Tags on multiple VMs with VMware PowerCLI!!
Hi All,
I want to introduce Aman Sapra VMware TAM as a Guest blogger for this post. Aman has helped us to automate creation of Categories and tags for multiple virtual machines for one of the customers.
The ask was to associate VMs with multiple tags and later call the same tags in vROPs to create custom groups.
The script worked like a charm and we were able to meet all the customer requirements.
I want to use my blog as a platform to share this script created by Aman.
Thanks Aman. Appreciate your efforts in helping us with this powerful script.

Upgrade vRealize Operations Manager from 6.6.1 to 7.5
Hello,
We recently upgraded vRealize Operations Manager at one of my customers environment from 6.6.1 to 7.5.
There has been a 6.7 and 7.0 version released before but since allocation model was discontinued in both the versions we decided to hold on to the upgrade until allocation model is back.
The customer was using a lot of allocation based metrics to perform capacity planning in advance and just using the utilization metrics was not viable.
Once the 7.5 version was out and the allocation model was brought in after hearing feedback from lot of customers we decided to upgrade our vROPs version.
Before you start, it is important to perform an interoperability check of vROPs 7.5 version with all the other solutions integrated with vROPs.
It is very important to run the pre-assessment upgrade pak to know the dashboards, reports, MPs, metrics and super metrics which will be impacted and what are the alternate metrics available if there are any.
In our case listed below metrics were impacted and we managed to find out some alternate metrics against it to minimize the impact.
I was working with vROPs Engineering team to work on this and find out a metric which does not have a replacement metric available.
You may also have to create a super metric where there is no replacement metric against it.
| Metric Name | Metric Key | Replacement Metric Name | Replacement Metric Key |
| CPU|Allocation|Computed Demand | cpu|alloc|base.demand | vCPUs Allocated on all Powered On VMs | N/A |
| Memory|Total Capacity | mem|actual.capacity.normalized | Memory|Total Capacity | mem|guest_provisioned |

| CPU|Allocation|Usable Capacity | cpu|alloc|object.capacity | CPU|Allocation|UsableCapacity | This is the number of vCPUs multipled by overcommit ratio setting defined in policy, and MINUS vsphere HA |

Once you have this sorted the next step is to download the OS and the VA upgrade pak file from here
https://my.vmware.com/web/vmware/details?downloadGroup=VROPS-750&productId=875&rPId=32115
vRealize Operations Manager – Virtual Appliance Operating System upgrade
File size: 2.31 GB
File type: pak
vRealize Operations Manager – Virtual Appliance upgrade
File size: 1.82 GB
File type: pak
The first step is to peform a OS upgrade and then the VA upgrade.
Before you initiate the upgrade ensure you have necessary backup available to return to the original state in case it is required.
Logon to the management interface of vROps using https://<vrops>/admin URL:
The next step is to take the cluster offline.
Select Software update, Install a software update and first upload the OS update PAK file.
Upload the OS update PAK file.The upload will begin staging and then let the upload 100% complete.
Select I accept the terms of the agreement
Read the update and release information before you click on Next
To start the update click Next
The installation of the OS upgrade is now in progress.
The upgrade for vRealize Operations Manager Enterprise OS update is now complete. You can now see the new version 7.5.0 build number 13165947
Now the next step is to follow the same process for the vROPs 7.5 application PAK file.
Click on Install Software Update and then upload the vRealize Operations Manager – Virtual Appliance upgrade PAK file.
Let the PAK file 100% upload.
Once the PAK file is 100% uploaded, validate it and then click Next.
Accept the terms and conditions and click Next.
Review the update and release information and click Next.
Now click Install to start the update.
The application upgrade is now in progress and the vRealize Operations Manager admin UI becomes unavailable for a small moment.
Once the UI is back login to the admin portal again and check the current progress and monitor the upgrade to complete successfully.
Once the upgrade is completed successfully login to vROPs main UI and validate the current installed version.
Post the validation is successful do remember to delete the snapshots from all the nodes that you would have taken before initiating the upgrade.
Hope this helps!

From VMworld: Introducing Project Pacific!
Today VMware announced Project Pacific, what I believe to be the biggest evolution of vSphere in easily the last decade. Simply put, we are rearchitecting vSphere to deeply integrate and embed Kubernetes. Project Pacific evolves vSphere to be a native Kubernetes platform. What’s driving this shift? Fundamentally it goes to what constitutes a modern application. The post Introducing Project Pacific appeared first on VMware vSphere Blog.
