Automation: Deploy multiple brand ESXi servers 7.0 using kickstart.

Nacer_Bell — Mon, 14 Jun 2021 13:00:59 GMT

Hi,

Need your help on this. We are starting a project to rebuild all unsupported ESXi 6.0 version to 7.0. We do have at least 200 servers and I need your help to direct me to the most productive way to automate this rebuild process. We need to install ESXi 7.0 using the same network configuration without any interaction and install multiple servers in parallel.

Thanks in advance!

Hi,

I'm having exactly the same issue in my VCSA 6.5, I did not find vumUtils.py so I'm not sure how can I apply this patch?

Appreciate your help !!

No we do not take this in a specific account, but we do run a periodic capacity report on our vmware infra.

Hi LucD,

What do you already have as a script?
Honestly, I’m just starting to think about building the script from scratch and I will be glade if someone did this kind and pre-check in his environment that I can re-use for mine.

Do you have overcommitment rules in place for CPU and memory?

For memory yes, all VMs should have their allocated memory reserved

Are you using Thick or Thin disks? Thick

If using Thin, what is your maximum overcommitment percentage?

Are you taking the order of VMs in the input file into account?

No, we are receiving the order of the VMs as a spreadsheat file, not sure what you mean by account.

When the 1st VM is created, the available resources change.

I’m not deploying any VM, just doing resources pre-check to make sure that we are covered

Hope this answers your questions

Hi,

Need your assistance to point me to some scripts portions which may help me to build a pre-check and validation script before I deploy some new VMs in my VMware environment. For your information I have no DRS, or HA set in my environment, let say it’s pretty static.

Usually I receive a xls file with the list of VMs to deploy which contain the ESXi hostname, Storage name (local or LUN) vCPUs, vRAM, vDisks, all the required VLANs. The goal of my script is to check all required resources for the new VMs vs what I have as a capacity resources on the hosts and the SAN as well. This script should build a csv file as an output report and should contain all the results.

Here is a sample of what we have as info in my xls file

ESXi_Host VM_Hostname Datastore vCPU vRAM (GB) vDisk #1 (GB) vDisk #2 (GB) vDisk #3 (GB) vDisk #4 (GB) vDisk #5 (GB) vDisk #6 (GB) vDisk #7 (GB) vDisk #8 (GB) Total (GB) NIC #1 VLAN Name NIC #2 VLAN Name

I may deploy multiple VMs on a single ESXi host, so I need to calculate on needed resources with what we really have on our ESXi host and on the storage side as well.

Thanks in advance!
