Quick Tip - Using ESXCLI to upgrade ESXi 8.x throws MemoryError or Got no data from process

by // 28 Comments

Several users in the community have reported running into a memory error issue when attempting to upgrade their standalone ESXi hosts using this ESXCLI trick, which has been possible since ESXi 5.1 back in 2012.

[MemoryError]
Please refer to the log file for more details.


Initially, I was not able to reproduce in my lab environment at work, which was running ESXi 8.0 Update 2, but I still got an error message but it was different:

Got no data from process.
Command "LANG=en_US.UTF-8 /usr/lib/vmware/esxcli-software sources.profile.list -d "https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml" "
Π΅xited with error code: 1


After checking my homelab environment which was also running ESXi 8.0 Update 2, I did see the same MemoryError message as reported by the community when using ESXCLI to list the available ESXi Image Profiles from VMware's online patch repository.

Determining new VMware vSphere Foundation (VVF) & VMware Cloud Foundation (VCF) license usage in vSphere 8.0 Update 2b

by // 14 Comments

vSphere 8.0 Update 2b was just released last week and with this release, customers can now take advantage of the new included 100 GiB trial vSAN storage capacity for each deployed VMware vSphere Foundation (VVF) core for use with vSAN!

Note: If you would like to understand how much vSAN storage you are entitled to (100GiB for VVF and 1TiB for VMware Cloud Foundation (VCF)), check out the new inventory and calculator script in KB 95927 (brownfield) and KB 96426 (greenfield) for more details.

In addition to installing and/or updating your vCenter Server to vSphere 8.0 Update 2b, you will also need to login to Customer Connect to download your new VVF and/or VCF license keys that will activate your vSAN entitlement.

I have already received questions on how to determine whether an ESXi host has been licensed with the new VVF and/or VCF license keys and which you can do so by using the vSphere UI by navigating to Administration->Licensing->Licenses->Assets->Hosts or vSAN Clusters and using the various filters, but this can be time consuming when you have a large environment with various license editions.

This is where automation and vSphere API can help!

Quick Tip - ESXi 8.0 Update 2b resolves not detecting Apple NVMe

by // 26 Comments

There was an issue that was reported last November where ESXi 8.0 Update 2 was not detecting the onboard Apple NVMe device during an upgrade and I am happy to share the mentioned fix will be available as part of the pending release of ESXi 8.0 Update 2b release, which is schedule for today (02/29/24)!


When you boot into the ESXi 8.0 Update 2b installer, you should now see the Apple NVMe device, which may also contain your ESXi installation and you will be able to select it and upgrade!


Disclaimer: Support for ESXi on Apple Hardware (Mac Pro and Mac Mini) has officially concluded with ESXi 7.x, so this is purely for informational and/or for homelab use purposes.
