Part 29: HOW TO: FIX No coredump target has been configured. Host core dumps cannot be saved

Sunday, September 29th, 2024

This video builds on the last videos in this series of Hancock’s VMware Half Hour, where we continue to build our VMware vSphere 7.0 Lab, and in this video, we start to explore the Warning messages appearing on several of our hosts in the cluster.

In this video, I will show you HOW TO: FIX the No coredump target has been configured. Host core dumps cannot be saved. There have been some changes in ESXi 7.0, and the core dumps can now only be written to SSD, HDD, NVMe, not persistent storage such as USB flash drives or SD cards. I discuss some of the issues with ESXi 7.0 and the support of USB flash drives and SD cards. There has been some confusion over the last 18 months about the support of ESXi 7.0 on USB flash drives and SD cards, VMware, Dell and HPE state there were not supported, because 7.0.2 or later caused issues with corruption of the ESXi installation if installed on these devices, and later VMware stated this was deprecated,. and then more recently did an about turn and not it’s supported.

SD card/USB boot device revised guidance (85685)

I think the “writing is on the wall” and if you are in a production environment using USB flash drives and SD cards, now is the time to change to SSD, HDD, NVMe or SATADOM for ESXi installations.

Sunday, September 29th, 2024

In this video, I will show you how to HOW TO: Add a Synology NAS providing NFS Storge to VMware vSphere Hypervisor ESXi 7.0. I will show you the process of creating a storage pool followed by a btrfs volume, enabling NFS and Exporting the NFS volume and connecting to VMware vSphere Hypervisor ESXi 7.0, by creating a dedicated storage network using a VMkernel portgroup for NFS traffic.

I will show you how to troubleshoot and check using simple bash tools ping and vmkping, that NFS traffic can reach the NAS.

The syntax I’m using in this video to test network communications between VMkernel portgroups and NAS (NFS), and check for jumbo frames.

ping <IP address>

vmkping -I vmkX <IP address> -s 9000

where X is a number of your VMkernel portgroup

In this video, I make reference to the previous videos written articles

Part 19: HOW TO: Update VMware ESXi 7.0U1 to ESXi 7.0U2a using vSphere Lifecycle Manager (vLCM).

Thursday, September 19th, 2024

This video will show you how to update ESXi 7U1 to ESXi 7.0U2a using VMware vSphere Lifecycle Manager (vLCM) to get your system up to the latest release. In this tutorial, the version of ESXi 7.0 installed is ESXi 7.0U1, but this video can be followed to upgrade any version of ESXi 7.0. If you do not have vCenter Server 7.0,  and your ESXi host has access to the internet, there is a method shown in this video – HOW TO: Update VMware ESXi 7.0U2 to ESXi 7.0U2a direct from VMware.

VMware has removed many older legacy processors (CPUs) from ESXi 7.0U2, and also storage and network controllers. Please check the VMware Hardware Compatibility Lists (HCL) here.

It is not recommended to install ESXi 7.0 on USB or SD cards because of higher write I/O, and the SD cards are currently suffering because they are not higher endurance. Problems have been found in the wild.

It is technically still supported; eventually, this may filter down through the server vendors…

Some additional information regarding the use of USB and SD cards with VMware vSphere Hypervisor 7.0 (ESXi 7.0) and installations.
