In this video we will cover how to import your existing vSphere environment to a VMware Cloud Foundation (VCF) deployment. With the SDDC Manager already deployed, we will see how we can import our environment into a new Workload domain. After the deployment we will see what changes […]
In this video we will cover how to add a New vSphere Cluster to a VMware Cloud Foundation workload domain. We will cover how to commission hosts and more importantly examine the various network settings that are available to us during this process.
Parsing complex HTML is definitely challenging, even with PowerShell. I had hoped to use the free tier of ChatGPT and their latest 4o model to help build a PowerShell function for HTML parsing, but I kept running into system limits and the AI often misunderstood what I was asking for. I finally […]

vCenter Server requires a Key Management Service (KMS) for enabling VM Encryption, vTPM, or vSAN Encryption. Users have the choice of configuring the embedded Native Key Provider (NKP) built into vCenter Server and/or use an external KMS with the Standard Key Provider (SKP) option. […]
The lsdoctor utility is a critical tool for diagnosing and resolving issues related to VMware Lookup Service (LS) problems. However, when running this script on VMware vCenter Server 8.0.3.00000, administrators may encounter a specific error if the system’s login banner has been customized.
🚨 Common Issue: Script Fails Due to Custom Login Banner
If you’ve modified the /etc/issue file—often used to display a custom login message—you might face an error when attempting to run the lsdoctor.py script:
❌ Example Error Output
[ ~/lsdoctor-240201 ]# ./lsdoctor.py -l
Traceback (most recent call last):
File "/root/lsdoctor-240201/./lsdoctor.py", line 547, in <module>
main()
File "/root/lsdoctor-240201/./lsdoctor.py", line 458, in main
params = parameters()
File "/root/lsdoctor-240201/./lsdoctor.py", line 136, in parameters
params = get_params()
File "/root/lsdoctor-240201/lib/utils.py", line 1349, in __init__
version, build = _getVersion()
File "/root/lsdoctor-240201/lib/utils.py", line 145, in _getVersion
version = version.rsplit(' ',1)[1]
IndexError: list index out of range📌 Root Cause
The script parses the /etc/issue file to extract the vCenter version. A custom banner or any deviation from the expected format can break this parsing logic, leading to the IndexError.
✅ Resolution
To resolve this issue:
This simple adjustment will allow the script to read the version correctly and execute without error.
🛡️ Impact/Risks
📝 Summary
The lsdoctor tool remains a powerful utility for vCenter troubleshooting—but like many scripts, it relies on predictable system configurations. When customizing system files like /etc/issue, remember that such changes may impact automated tools that parse system info.
If you’re running into this error, follow the steps above to restore the default login banner temporarily, run the tool, and then revert back. A little precaution can go a long way in avoiding unnecessary troubleshooting headaches.
