VMware – Enabling SSD Option on SSD Disk or LUN with ESXCLi on VMware ESXi Host 6.x

Summary

Are you running a VMware ESXi 6.5 or 6.7 host without vCenter, and noticing that an SSD-based disk or LUN is incorrectly listed as “Non-SSD” in the web console?
The following steps show how to manually correct the Drive Type using ESXCLI.

Description

Some SSDs or SSD-backed LUNs are not automatically recognized as SSDs by ESXi. This guide explains how to manually enable the SSD flag for such drives using the ESXCLI command-line tool.

Configuration Steps Using ESXCLI

Get all storage devices:

esxcli storage nmp device list

Values needed from the preceding command:
– Device Name: naa.62cea7f074dddc0027486e5212048ad5
– Storage Array Type (SATP): VMW_SATP_LOCAL

Enable the SSD Option:

esxcli storage nmp satp rule add --satp VMW_SATP_LOCAL --device naa.62cea7f074dddc0027486e5212048ad5 --option "enable_ssd"
Restart the VMware host to apply the changes.

Result

The SSD Disk or LUN have now the correct SSD Option.
