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.
