During an upgrade of a DELL PowerEdge R730/R830 server, we have increased the RAM from 24 GB to 88 GB and CPU from 1 to 2. After booting the system when we checked from the BIOS we found the system is showing 2 CPU but showing RAM only 72 GB, 2 RAM of 8 GB was not installed correctly. At that time we were not able to identify the slots for which RAM was detected.
Later I googled how to find system info, processor info, cache info, memory info, port connector details etc. and found the command smbiosDump through which we can get all the details related to the system hardware and the ESXi command-line interface (CLI) after login as root.
How to check System and Hardware Information on a Linux Server
HP-UX command to get Physical Memory Information
To log in to the ESXi shell as a root, the SSH service should be enabled and running on the ESXi host. To enable it you need to login to the ESXi host through vSphere Client and go to Configuration >> Software >> Security Profile >> Properties select SSH click on options and start the SSH service.
System Information
After login into the ESXi host run the smbiosDump command to get the system information.
